SEA BISCUITS: THEY REALLY DO CONTAIN DOVES – AND MORE!

SEA BISCUITS: THEY REALLY DO CONTAIN DOVES – AND MORE!

Recently I posed the question whether sea biscuits, like sand dollars contain ‘doves’. I had one in my hand, it rattled, I took a photograph through its ‘mouth hole’ and the question was answered. Biscuits do indeed contain doves – see HERE for details and comparisons with dollar doves.

However, I spinelessly* failed to break open the biscuit to check out the contents more closely. I theorised that, because of the 5-way symmetry of these creatures, there would be 5 doves (which are in fact segmented mouth parts) in a biscuit exactly as with a dollar, and amiably challenged anyone to disprove it. [* biscuits and dollars are types of sea urchin – see what I did there?]

Melissa Ann Guinness from Hope Town has a far more robust attitude to these things and, taking up the challenge, she heartlessly smashed open a sea biscuit from her collection to investigate further. I said I’d publish a correction if my theory was wrong. This is it – though in one arguable sense the theory holds good. It just didn’t go far enough…

In the above picture you can see (a) 4 quarters of a sea biscuit skeleton (b) 10 demi-doves (rather than 5 whole doves) and (c) a small mummified 5-limbed brittle star that was presumably in the creature’s digestive system when it died.

SEA BISCUITS: DO THEY REALLY CONTAIN DOVES?

SEA BISCUITS: DO THEY REALLY CONTAIN DOVES?

A couple of years ago I wrote a post called ECHINODERMS, DOLLAR DOVES & PETRIFIED BISCUITS. It dealt with the… fact? rumour? old wive’s tale?… that within each sand dollar test (i.e. the white skeleton) are hidden 5 ‘doves’. You can hear them rattling inside if you shake the dollar… 

Sand Dollar Doves (Keith Salvesen) 6

Sand Dollar from Abaco containing 5 miniature white doves…

I investigated the theory with senior granddaughter, and we broke a sand dollar in half. And as you can see, the answer was undoubtedly yes – there were 5 tiny white doves, thus fulfilling the prediction of the famous ‘Sand Dollar’ poem that contains the lines  “Now break the centre open And here you will release The five white doves awaiting To spread good will and peace”.

Five white doves (in fact, the separated parts of the creature’s feeding apparatus)Sand Dollar Doves (Keith Salvesen) 1

A single dove, a picture of dovelinessSand Dollar Doves (Keith Salvesen) 3

I never thought to extend the experiment to sea biscuits, another object prized by beachcombers. All that changed last month when I picked up a sea biscuit and found that it, too, rattled.

A rattling good sea biscuit

So I turned it over to take a closer look at the underside. And there, unmistakably, was the source of the rattle – some kind of internal arrangement inside the feeding  hole (let us not pause overlong to consider the purpose of the other hole). But it wasn’t conclusively a dove.

So I shook it around a bit (sorry, doves) and zoomed in. And there was a small white columbine-type contraption remarkably similar to those found in the dollar dove. And no, I did not smash open the sea biscuit (it wasn’t actually mine). And no, I didn’t doubt any longer that sea biscuits also contain doves.

SO WILL THERE BE 5 DOVES, LIKE WITH THE DOLLARS?

I predict there will also be five. Both dollars and biscuits have ‘five-way symmetry’ (look on the topside of a biscuit or dollar to see how); and so the mouth (from which the ‘doves’ derive) will have a single part for each of the five sectors, all linked. 

If anyone would like to smash up one of their precious beach finds and test the theory, please feel free. Prove me wrong… and I’ll publish a correction! [Photo please…]

SEA GLASS TREASURES & TWO ISLAND CHICKS…

SEA GLASS TREASURES & TWO ISLAND CHICKS…

It’s time to shine the Rolling Harbour spotlight on sea glass, a neglected (by me) topic recently . Everyone loves it (don’t they?), and there’s always a bit of excitement in finding a pretty piece of cloudy glass gleaming in the sand on the beach. Just look at that colour. Might it be rare? How old could it be? Should I pick it up or leave it for someone else to enjoy? 

Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

Collecting sea glass is one of the pleasures of a walk on the beach. Or maybe it’s the motivation for the walk. For some, it is an opportunity to turn what the sea throws onto the beach into something decorative. Abaco is home to some excellent jewellery** makers who specialise in using locally found materials to make beautiful things. These sometimes incorporate a mix of sea glass, pebbles, and small shells.

Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

In Hopetown on Elbow Cay, Hilary Thompson and Erika Feszt Russell do just that. Trading under the name ‘Two Island Chicks’, they use sea glass in many of their creations, some examples of which are displayed here. As you’ll see, they also apply their creativity to showing their jewellery attractively. 

Sea Glass & Jewellery, Abaco, Bahamas (Two Island Chicks)

The collected glass has to be sorted into the various colours. Most are quite common (white, green, brown), some are uncommon (eg cobalt blue), and just a few that are very rare – and possibly valuable (red, orange) – see charts below.

The charts below give a general overview of the comparative rarity of various sea glass colours, their sources, and the chances of making a rare find. Of course, these are mainstream colours; there are many other in-between hues and shades.

“THE ADMIRABLE CHITON” (A DELPHI BEACH MYSTERY)


Fuzzy Chiton, Delphi, Abaco (Kasia Reid)

“THE ADMIRABLE CHITON” (A DELPHI BEACH MYSTERY)

The beach at Delphi is good for combing. Most of Abaco’s beaches are too, for that matter. You can find Kasia’s beachcombing page HERE. Last month 2 guests, Linda and Jan, went exploring on the beach and returned with a handful of mystery items they had found under the clumps of seaweed. These were clearly neither complete nor broken shells, and even after some research in books and online I remained baffled. They were obviously parts of some water-based species… but what parts, anatomically speaking? And what species?

Fuzzy Chiton valves (segments), Delphi Beach, Abaco, Bahamas

So I contacted Colin Redfern, Bahamian sea shell expert and author of a magisterial tome on the subject. His response was typically swift and definitive: 

The ladies have found some beach-worn valves from the common Fuzzy chiton, which was so nicely photographed by Kasia on your April 12, 2012 entry – (the one that included fecal pellets) [See Header]. As you know, the meat from this species is eaten by Bahamians, who discard the unwanted shell. The individual plates then become separated by wave action and normal deterioration. Abaco has a pretty good selection of chiton species, and individual valves from some of the other species are sometimes found on beaches.
Fuzzy Chiton, wiki

Chitons (pron. kytens) are marine molluscs with a great many species worldwide, from very small to quite large. Their shell comprises 8 interlocking and overlapping curved plates known as ‘valves’ that provide a flexible protection, and articulate as the creature moves. Chitons – at least some species – can even curl up into a protective ball. The plates are held together by a ‘girdle’ surrounding the animal.

Acanthopleura_granulata_(West_Indian_fuzzy_chitons)_(San_Salvador_Island,_Bahamas) James St. John

Fossil records show that these primitive-looking animals derive from the Devonian period – or even Ordovician. They remind me of trilobites, even older creatures from the Cambrian period that used to fascinate me at school when I was small and paying attention. The name chiton derives from Latin word for mollusc, which itself comes from an older Greek word meaning a tunic. Which they in no way resemble.

Fuzzy Chiton, Abaco (Kasia Reid)

After a chiton dies, the valves which make up the eight-part shell come apart because the girdle no longer holds them together and these the plates may wash up in beach drift, to be found by Linda and Jan. The individual shell plates are sometimes known as “butterfly shells” due to their shape.

A DOZEN CHITON FACT TO AMAZE YOUR FRIENDS WITH

  • Chitons are also known as ‘sea cradles’ or ‘coat-of-mail shells
  • Their shell consists of 8 plates / valves so flexible that they can even curl into a ball
  • They move with a muscular ‘foot’, and use it to cling onto rocks like a limpet
  • They have no definable head, no tail and no eyes, onlyphotoreceptor cell clusters’
  • The mouth on on the underside of the chiton
  • It contains a sort of tongue – a radula – with rows of teeth, each with 17 (why 17?)
  • They use the radula to scrape the rock substrate for algae and similar
  • A chiton’s digestive system produces neat little fecal packages like white pills
  • Its anus is next to its foot, a design mercifully not found in humans
  • I learn that chitons “lack a cerebral ganglion”. I think this means, no brain as such
  • However they do have a primitive ‘homing’ ability too complex to summarise…
  • Chitons are eaten by people mainly in the West Indies and the Philippines

Chiton, Abaco 2 (Kasia Reid)

WHAT? YOU CAN EAT THEM?**

If you are asking that question, you perhaps read right through the 12 facts to the very last one. If so, you deserve an answer and indeed a recipe for Chitons aka ‘Sea Cockroaches’. And who better to provide it than the brilliantly-named PSYKDELIASMITH Click the link to find out more.

**CAUTION As a couple of people have rightly pointed out (thanks Liann and Julias) since I posted this, not all chitons are edible. Some are poisonous. So before you think of a culinary chiton caper, best check that you have got an edible one

Colin Redfern kindly sent me a pdf of the chiton section of his book. Of the fuzzy chiton he writes: “Occurrence: Very common intertidally on rocky shorelines. Known locally as a Curb, with the meaty foot used as an alternative to conch in salads. Gutted specimens or disarticulated valves consequently common along shorelines.” Which is just where this post began.

POST SCRIPT This post has generated quite a lot of comment on Facebook. Here are a few, plus an amazing discovery in Hope Town
  • “Commonly know as a curb, they are edible (raw) you make a salad like you do with conch , delicious !!!” (Rosalie Pyfrom)
  • True some are poisonous, but your have to know which ones!! I was showed as a child which were good from bad!!” (Janice Carey Hall) 
  •  “Very delicious” (Cantrell Walker)
  • “Lets not forget the poisonous ones!” (Julias Sawyer)
  •  “Don’t mess wit my curbs, nom nom”  + “Definitely do NOT eat the very large ones with the bumpy rim”.(Liann Key Kaighin)
  • “Curb stew is a Bahamian food that has since the loyalist arrived” (Steve Roessler)
 Gary Richardson Jr.'s photo.

Then Gary Richardson Jr added a photo of what must be a pearl, found in a curb in Hope Town. 

 To which I replied “Well that’s a surprise! Interesting find. Did a bit of research. Apparently all shelled molluscs are capable of producing ‘pearls’ – though they have no value. So this must be a chiton pearl…”

ROLLING HARBOUR, ABACO: LIFE’S A BEACH & THEN SOME…

Rolling Harbour (the geographical feature) is a gently curving one-mile white sand bay presided over by the Delphi Club, which sits on a 50 foot cliff behind the beach. There are rocks at either end, fish in the sea (including bonefish and, in the right conditions, permit), birds on the shore and shells on the sand. And that’s it…

The shell species below (also in the header picture) is an olive. It turns out to have potential to star in a small maritime horror movie. Capt Rick Guest, who kindly keeps an eye on my shell and other sea-related posts, writes “Interestingly, the previous occupant of the first and last shell pictured here is a major predator of the other Bivalve shells shown. The Olive shell hides under the sand by day, then emerges at night to feast upon small Bivalves, and any other available prey. One can often trace the nocturnal trails of this Olive shell in sand on calm mornings with mask and snorkel, and thrust a hand under a trails end for this fellow. When kept in an aquarium, they will consume any meat offered.” “Olive and Let Die”, maybe?Abaco Shell 3aAbaco Shell 7

SHORE THINGS: BEACHCOMBING ON A PRISTINE ABACO BEACH

SHORE THINGS: BEACHCOMBING ON A PRISTINE ABACO BEACH

The Abaco bay known as Rolling Harbour is a 3/4 mile curve of white sand beach, protected by an off-shore reef. The beach is pristine. Or it would be but for two factors. One is the seaweed that arrives when the wind is from the east – natural and biodegradable detritus. It provides food and camouflage for many species of shorebird – plover and sandpipers of all varieties from large to least. The second – far less easily dealt with – is the inevitable plastic junk washed up on every tide. This has to be collected up and ‘binned’, a never-ending cycle of plastic trash disposal. Except for the ATLAS V SPACE-ROCKET FAIRING found on the beach, that came from the Mars ‘Curiosity’ launch. Sandy's Mystery Object

We kept is as a… curiosity, until it was eventually removed by the men in black…

Shore Things 14I’d intended to have a ‘plastic beach trash’, Atlantic-gyre-rage rant, with angry / sad photos to match. Instead, I decided to illustrate a more positive side to beach life – things you may discover when you take a closer look at the sand under your feet. Like the coconut above. Many of these photos were taken by our friend Clare Latimer (to whom thanks for use permission); some by me.

Thanks to Capt Rick Guest, who has contributed an interesting comment regarding the sea biscuit with a hole in it. He writes “the (Meoma) Sea Biscuit w/ the hole in it was dined upon by a Helmet Conch. The Cassis madagascariensis, or C.tuberosa drills the hole w/ its conveyer-belt-like radula teeth w/ some help from its acidic, saliva. Probably 98% of all symetrical holes in marine invertebrates are of this nature. Murex, Naticas, Helmets, and many Cephalapods (via a Stylet), are the usual B&E suspects. The Cone shells utilize a modified radula in the form of a harpoon which is attached to a venom tube.” For more on the vicious cone shell, and other creatures to avoid, click HERE

BEACHCOMBING: AN INVASION OF BEADS AT ROLLING HARBOUR

BEACHCOMBING: A BEAD INVASION AT ROLLING HARBOUR

The Delphi Club beach at Rolling Harbour is an undeniably beautiful 3/4 mile curve of white-sand bay, shelving gently into pale blue water. Many interesting things get washed up on the shore, besides shells, sea glass, and vast quantities of seaweed (with a fair amount of junk) that must be regularly cleared. It’s a good place for desultory beachcombing, and some of the finds have featured in earlier posts, with the help of KASIA

Delphi Club, Rolling Harbour, Abaco

Of course that is not in the least unusual in these parts, though Delphi can claim the unique distinction of a 12 foot booster rocket fairing from the Mars ‘Curiosity’ launch, washed up early in 2012 (see short posts on the developing story at ONE & TWO & THREE)

Sandy's Mystery Object

There are large glass and wooden floats. Things that might be car parts. Wooden pallets. Not, as yet, any of the yellow plastic ducks so often written about (see book review of MOBY DUCK). Now, we have an invasion of coloured beads. 2012 has been a prime year for bead beachcombing, a specialist field. At times, guests have had a field day (if you can have one of those on a beach?) collecting these small beads. One large flagon has already been filled and, as Peter Mantle observes, “our cup runneth over”.

An important Christmas task – and not a difficult one, I envisage – will be to empty another suitably large vessel. Drinking is likely to be involved. Meanwhile, an explanation for this beach bead influx over many months would be good to find. A container of children’s toys sadly washed overboard? Evidence of some arcane fishing method? An explosion in a necklace factory? Beads deemed unsuitable for rosaries? Rejects from the World Marbles Convention? Has anyone else experienced finding these multicoloured beads on their local beaches? I know that a few beachcombers follow this blog (thanks!) from other parts of the world. Any beads? All contributions by way of the COMMENT link, or an email to rolling harbour.delphi[at]gmail.com, welcome.

FLAMINGO TONGUE SNAILS & SHELLS: COLOURFUL GASTROPODS OF THE CARIBBEAN


FLAMINGO TONGUE SNAILS & SHELLS: COLOURFUL GASTROPODS OF THE CARIBBEAN

AN UPDATED VERSION OF THIS POST WITH NEW IMAGES AND MATERIAL (AS WELL AS A RETREAD OF SOME OF THIS POST) WAS POSTED IN NOVEMBER 2014 AND CAN BE FOUND HERE

The FLAMINGO TONGUE SNAIL Cyphoma gibbosum is a small sea snail (marine gastropod mollusc), related to cowries. The live animal is brightly coloured and strikingly patterned, but that colour is only in the ‘live’ parts – the shell itself is pale and characterised by  a thick ridge round the middle. These snails live in the tropical waters of the Caribbean and wider western Atlantic. Whether alive or dead, they are easy to identify.

This snail on the left (thanks, Wiki) is snacking on a coral stem, leaving a feeding track behind it. The structural shell ridge is clearly visible beneath the distinctively marked live tissue.

The flamingo tongue feeds by browsing on soft corals. Adult females attach eggs to coral which they have recently fed upon. About 10 days later, the larvae hatch. They eventually settle onto other gorgonian corals such as Sea Fans. Juveniles tend to live on the underside of coral branches, while adults are far more visible and mobile. Where the snail leaves a feeding scar, the corals can regrow the polyps, and therefore predation by C. gibbosum is generally not harmful to the coral.

The principal purpose of the mantle of  tissue over the shell is as the creature’s breathing apparatus.  The tissue absorbs oxygen and releases carbon dioxide. As I have seen it described (unkindly?) “it’s basically their lungs, stretched out over their rather boring-looking shell”. 

This species was once common but is becoming rarer. One significant threat comes from snorkelers and divers who mistakenly think that the colour is the shell of the animal, collect up a whole bunch, and in due course are left with… (see photos below)

These photos are of flamingo tongue shells from the Delphi Club Collection. Until I read the ‘boring-looking shell’ comment, I thought everyone thought they were rather lovely… you decide!

Finally, a couple of videos. The first is rather charmingly titled ‘FLAMINGO TONGUES DOING…. SOMETHING’. Any (printable but amusing) suggestions via the Comment box are welcome (Hi Trish!). The second punchily summarises this post. Maybe that’s all that was needed!

CURIOSITY landed on Mars today. This is the best chance yet of answering Ziggy Stardust’s rhetorical question “Is there life on Mars?”, and doffing an astronaut’s helmet to space pioneer Major Tom along the way… Assiduous readers of the blog will both recall that a while ago, the Delphi Club was privileged to be involved in a small part of the ‘Curiosity’ Mars Rover project. It’s a prime example of what one might call “extreme beachcombing…”

“One small part for a space program, one giant chunk of junk for the Delphi beach…” (S Walker)

The episode had a slightly bathetic ending. Initial lack of official interest in the cone, which I personally hoped could then be planted deep in the coppice or pine forest for future generations to discover and wonder about, suddenly changed. In due course a team of astro-science persons (in a large black truck and white protective suits, I’d like to believe) came and took it away. This forestalled my other idea: cutting it up into hundreds – or thousands –  of small pieces and selling them on eBay (possible in aid of the Abaco Parrots). A 12 foot cone of gleaming heat-resistant secret Abaconite space material. 5000 tiny pieces @ $100 each… Hmmmmmmmmm

1ST ANNIVERSARY “ESSENTIAL ABACO WILDLIFE FACTS” COLLECTION


Today is the 1st birthday of this blog, on the very day that the hit count passes 37,000. I started out last April, with faltering steps, into the mysterious world of the blog – setting it up, getting ‘stuff’ posted, finding out about birds, creatures, shells and much else from scratch. The learning curve has modified slightly and has a less vertiginous ascent. We are now mostly under control here at Rolling Harbour HQ… It’s been a year of Parrots, Whales, Hurricanes, Mars Probe Booster Rockets and other beachcombing mysteries. As year 2 begins, huge thanks to the many who have contributed so far, or generously given advice and (mainly) constructive criticism along the way, or simply taken the time to have a look. Especially if you came back for more…

Here to celebrate the day is the Official Rolling Harbour Collection of  some of the “Essential Facts” that have appeared in various posts over the previous year. It is, needless to say, essential reading. Amaze or alienate your friends with your esoteric knowledge of the length of an adult male manatee’s intestines…

ESSENTIAL HUMMINBIRD FACTS

  • The colourful throat of a (male) bird is known as a ‘gorget’
  • Hummingbirds are the only birds that can fly backwards
  • There are 320 species of hummingbird worldwide
  • The smallest is the bee hummingbird of Cuba, at 2″ for an adult
  • John Gould, the c19 ornithologist and artist, invented many of the names to reflect the varied and iridescent colours of the birds.
  • Hummingbird wings beat as much as 75 times per second
  • Hummingbirds have the highest metabolic rate of any warm-blooded creature; also the largest hearts (proportionately, obviously…)
  • There are many collective nouns, including a “bouquet”, “glittering”, “hover”, “shimmer”, and “tune” of hummingbirds
  • On the TCI, the Bahama Woodstar is known as ‘The God Bird’ 

10 MEMORABLE MORSELS OF MANATEE MINUTIAE

  • The 4 species of Sirenia are the West Indian, Amazonian and West African manatee; and the Asian / Pacific dugong. 
  • Fossil remains of Florida manatees date back 45 million years; their closest living relative is the elephant
  • Manatees are also known as Sea Cows. Some say sailors who’d been at sea for too long took them to be mermaids, a mistake I doubt they made twice…
  • They can weigh up to 1,300 lb and measure up to 13 feet. Females are larger than males. Baby manatees may weigh 65 lb. Adult intestines can reach 45 meters which would take Usain Bolt 4.31 seconds to run past (if straightened out, obviously)
  • Accurate population estimates seem to be impossible to obtain, varying by season and by year for no apparent reason. Overall,  the picture is of a declining population, with extinction likely without further protection
  • West Indian Manatees can move freely between extremes of salinity, and may be found in warm shallow coastal waters, in estuaries, or migrated into rivers to freshwater springs (as in Florida). They cannot survive below 15°C (60°F). They have a propensity to hang around the warm-water outflows of power stations
  • Manatees have some intelligence and demonstrate discrimination and task-learning similar to dolphins.Their eyelids close “in a circular manner”, though I can’t quite picture this. They have only 6 teeth in each jaw, which are replaced throughout their lives
  • They breed every other year. Gestation lasts 12 months, and it takes a further 12 to 18 months to wean the calf. A single calf is born. Apart from mothers with a calf or males showing off to females, manatees tend to be solitary creatures
  • They are herbivores, eating many plant species, such as mangrove leaves, turtle grass, and types of algae. An adult manatee can eat up to 10% of its body weight per day. They have been known to eat small amounts of fish from nets
  • Half a manatee’s day is spent sleeping in the water. The rest of the time they graze in shallow waters. They swim at 3 to 5 mph, faster in short bursts. They may live up to 60 years (surprisingly, given their punishing daily schedule)
  • The oldest manatee in captivity is Snooty, at the South Florida Museum. He was born at the Miami Seaquarium on July 21, 1948 and came to the South Florida Museum in Bradenton, Florida in 1949

10 ESSENTIAL YET GRISLY MUREX FACTS

  • Murex are highly carnivorous with rasping teeth, and drilling equipment for boring into the shells of their prey
  • A determined Murex may take up to 5 days to drill into its prey
  • Murex also use their foot to smother prey, or to crush it by using suction power
  • They eat clams by hoovering them up with their foot and smashing them on rocks to get at the occupant
  • They happily eat sea-floor carrion and sea-kill
  • Murex act in packs to carry out raids on unsuspecting beds of clams, which they feast on avidly
  • They are sexually wanton. Females store sperm from different males for many months, eventually producing embryos with different dads (I’m not making this up. I would like to have done so)
  • Cannibalism occurs. The kids are equally prone to extreme delinquency and are happy to eat each other when peckish
  • Some species of murex secrete a fluid that is believed to be used to drug their prey into paralysis
  • That same fluid (Murex / Mucus) is also used as a dye, ‘Tyrian’ or ‘Royal’ Purple, which can be ‘milked’ from a living murex (the Aztecs & Phoenicians did this). I’ll pass on that…
POTCAKE POT POURRI
  • Potcakes are a mixed-breed dog of the Bahamas & TCI, named after the layer of dried rice and peas in  the bottom of cooking pots, traditionally fed to stray dogs
  • Appearance and colouring varies considerably from island to island. Mostly commonly they are (mainly) brown, have smooth coats, cocked ears, and long faces. Adults typically weigh from 45 to 50 pounds (20 to 23 kg)
  • Potcakes have a wandering tendency. There are many strays on every island – often considered a nuisance. Volunteer organizations re-home strays,  and offer free spaying and neutering
  • Potcakes are often used for hunting hogs. Some are trained to locate fish through  scent on the water and the cries of feeding sea birds
  • Potcakes may originate from 3 canine types: (1) dogs brought by the Arawak  to the Bahamas; (2) terriers protecting supplies from rodents on ships to the Bahamas; (3) Dogs that arrived with Loyalists during the Revolutionary War
  • In the 1970s the potcake dog was officially recognized in The Bahamas as the “Royal Bahamian Potcake”. In February 2011, they were accepted by the Bahamas Kennel Club in the category ‘Group 9 Non-Registered’
  • A potcake dog named Amigo has been the mascot of the Humane Society of Grand Bahama. He ‘served as an Ambassador of Hope for homeless animals’ until his death in 2007, and appeared on TV
  • Potcakes have featured in a set of special-issue Bahamas stamps (as have Bahama Swallows)

10 MEMORABLE FACTS ABOUT LIGNUM VITAE

  • Traditionally, it was used for making British Police Truncheons (now made of soft fluffy pink fabric to reflect new caring policing methods)
  • Its physical qualities made it widely used in shipbuilding (though presumably not the whole ship, which would sink instantly)
  • Cabinet-makers, stone-carvers and gem-cutters all use the wood in their crafts
  • LV has many engineering uses. The wood is self-lubricating and is ideal for bearings. The 1st nuclear submarine had some of these
  • The world-renowned  UK fishing rod maker Hardy’s made a famous ‘Greenheart’ rod
  • LV has medical uses, including for arthritis; and its bark / shavings allegedly make a nice cup of “tea”… (Any evidence of this?)
  • A 1920’s calypso song “LignumVitae” was sensationally saucy for its allusions to the bark tea’s prophylactic quality in addition to exploiting the phallic connotations
  • Gabriel Garcia Márquez incorporates uses for the wood in two of his novels (neither of which I have read. Oh dear. The guilt)
  • Pete Seeger, singer / songwriter, made the neck of his banjo from LV
  • The wood is also connected to mauve tiling, vitamin glue, anti-evil gum and the ‘vigilant emu’ by anagrammatic chance

SCOTCH BONNET FACTS

  • It takes approximately six years for a Scotch bonnet to mature
  • The shells grows 2 – 4 ins long (5 – 10 cm), showing distinct growth stages
  • Scotch bonnets live on sand, usually in fairly shallow water (but see below)
  • The more a Scotch bonnet eats the more elaborate its shell, the glossier its sheen & the brighter its colours (research suggests this doesn’t work for humans)
  • Divers frequently find Scotch bonnets at depths of 50 – 150 feet (15 to 46 m). Specimens have been found in depths up to 308 ft (94 m)
  • Shipwrecks provide a good habitat for this species
  • Crabs are its main predators, crushing the shell to get at the occupant. Since the snails’ main defence mechanism is to withdraw into their shells, they urgently need to evolve a new tactic
  • The empty shell of this sea species is often used by hermit crabs
  • In 1965 the state of North Carolina made the Scotch bonnet its official state shell, in honor of the Scottish settlers who founded the state

SHELLS OF THE ATLANTIC COASTS & WEST INDIES: PETERSON FIELD GUIDE


SHELLS OF THE ATLANTIC COASTS & WEST INDIES 

PETERSON FIELD GUIDE    Abbott / Morris   350pp

An excellent and comprehensive field guide which covers the area as thoroughly as one could wish. It’s not exactly a pocket book, and at 350 pages it’s quite a chubby paperback – but the sort of size you’d happily throw into a day-bag or backpack. This authoritative shell guide dates from 1947, with frequent reprints. Mine is a fourth edition (1995) – there may be a 2002 one.

Currently £18 from Amazon UK,  or new / used for around £7 (a bargain); and a great deal cheaper on Amazon US. Overall 4* reviews

Rolling Harbour rating *****

THE BOOK IN A CONCH SHELL

  • Numerous clear illustrative line drawings throughout (115, in fact)
  • 74 colour plates grouped together at the heart of the book, showing living creatures and a huge variety of shells – 780 in all
  • Introductory articles on collecting, preparing, arranging and naming shells; also classifications and measurements
  • The text comprises 800 brief but helpful family / species descriptions, with notes on habitat and other remarks
  • Bi-valves cover 120 pages; Gastropods a stonking 150 pages
  • The substantial illustrated core of the book has shell groups on the right-hand page, with ID and text references on the left. The system works very well, especially with the many shell types that are very similar
  • At the back there’s a useful ‘Conchological Glossary’ to help sort out the crenulates from the reticulates
  • A huge 30-page index that is both thorough and user-friendly
I personally found the illustration section very helpful as a first stop; then a trip to the text to confirm the description. I had no idea what a shell we recently found in a drawer might be, but it didn’t take long to nail the ID as a STOCKY CERITH a shell I’d never even heard of. First I found a very clear illustration of it, then turned to the text description which matched what I had in my hand. Overall, as a complete amateur, I found this book the best practical guide I have yet tried for shell identification – and I suspect more sophisticated shell-seekers will get a great deal out of it too.

STOCKY CERITH – A RANDOM ABACO SHELL FROM THE BACK OF A DRAWER


A RANDOM ABACO SHELL FROM THE BACK OF A DRAWER 

We recently discovered this shell loitering at the back of a drawer. It may well have been there for a couple of years… I had no idea what species of gastropod it might be, so I turned to a book I recently bought (and am about to review), the Peterson Field Guide on Shells. It is extremely thorough and well-illustrated, and almost at once I was able to pick the shell out as a STOCKY CERITH Cerithium Litteratum (Colin – are you still keeping an eye on the shell ID errors in this blog, I wonder? Later: yes… and he confirms the ID. Many thanks). It’s a couple of inches long and has 7 spirals before the tip part, with pronounced nobbles on the lowest 4. There’s a neat hole in it, but I don’t know whether caused by sea / beach damage or a predator. These creatures live in shallow water and are common throughout the Caribbean. So this one is nothing unusual, but I am pleased that it has eventually turned up…

BOOKCOMBING: AN OCCASIONAL THEMED SERIES (2) SEA GLASS


2. SEA GLASS

Note 1 I give Amazon.uk pricing as a simple standard for new / used prices. Obviously Amazon.com is also worth comparing, as is Abe UK or US. With Abe watch out for the shipping costs. An apparently ‘bargain’ book may have a loading on the shipping, which (unlike Amazon) are not standard.

Note 2 You will see that I have included books that have had bad reviews as well as good – compare books 1 and 2 below – so that you are forewarned…

PURE SEA GLASS

RICHARD LAMOTTE

Amazon UK £22; new / used from £14

Amazon UK Reviews 1 x 5*           

Pure Beauty “I loved this book… Sea glass is fantastic and this book shows you how to recognise each colour, although in reality there are thousands of hues! I loved the photographs in this book and it made me surf the Internet for sea glass collectors, sites etc.

Amazon.com reviews: 70,  average rating 4.9 out of 5*. Here are a few nibbles

Discovering Nature’s Vanishing Gems  “This is an excellent volume, especially for beginners… A major attraction is that there are over 150 exquisite and elegant photographs… presenting some of the beat specimens ever collected, along with a vast array of classical glassware from around the world that is often its source. The book is a comprehensive guide, chock full of information on finding and identifying these gems, the bits of aged glass, enhanced by years beneath the sea or caught in the tides that wash our coasts. There are 224 pages with chapters on the history of sea glass and the history of sand, (fascinating), different types of glass, (bottles, containers, tableware, utility and flat glass, like window glass – plain and stained, marbles, insulators and bonfire glass – from ship and shore, etc) & appraising rarity, along with many other interesting topics”

Simply Exquisite  “…a must have for all the beachcombers who wander the strands of the world, bending to pick up those gorgeous fragments of glass. It offers history & facts about the globs of glass washed up by the waves, as well as page after page of exhilerating colors & shapes the glass comes in, & images of the seashore”

SEA GLASS HUNTER’S BOOK

C.S.LAMBERT

Amazon UK £8.54, new/used from £5.07

This book has divided readers. It’s worth bearing in mind that it costs a lot less than most, so it can’t be expected to be as lavish. but still… here’s a flavour. I rather enjoyed the two snidey reviews, I’m sorry to say

Amazon.com reviews: 9, average rating 3.7*

The Good Review “It’s exactly what I hoped — SGHH is a celebration of sea glass hunting. Simply put: the book is stunning. As a previous reviewer noted, this is not a “how to” book nor a map (although it does list exceptional locations around the world); rather, it is like a piece of sea glass itself: beautiful, tangible, a treasure. Chapter 1 the world of sea glass; 2, origins; 3, methods for hunting; 4, lexicon; 5, etiquette & laws; 6, destinations. It’s digest size, hard bound & first class… I strongly recommend it for anyone who truly loves sea glass or who would like to share the passion with others

The Model Sniffy Review Intended for total novices, not for a true sea glass hunter… mostly a very broad overview of the sea glass experience, basically nice small pictures in color of perfect pieces of sea glass etc. The book is very small, the type of thing you find in a hallmark gift shop in the mall, designed obviously for gifting to a hospital patient or homebound person, a little birthday type gift, would be nice to give to someone at christmas time that has no idea what seaglass is, or for a pre-teenager to early teens in reading level perhaps. I had too high expectations for this book… it’s just a little puff piece. If you seriously collect sea glass and actively pursue this with any passion, you won’t find anything in this tiny volume of importance that you don’t already know”

The Serious Panning “Ho Hum. The most remarkable thing about this book is how undistinguished it is. A book on sea glass should either be beautifully designed or loaded with useful information, or both. This one is neither. The visual appearance is not unlike what one might expect in a high school project. In particular, the extensive grab bag of colorful and unrelated fonts is amateurish to the extreme. There’s a dearth of information for something purporting to be a “handbook”. The author has thrown together a variety of snippets seemingly without the benefit of an organizing thought process or theme. You can skim this skimpy volume or better yet you can simply skip it – I wish I had. Read Pure Sea Glass by Richard LaMotte instead (see review above. rh)

SEA GLASS CHRONICLES

REVIEW CLIPPINGS

1. The Overwrought (Suspected Publisher’s Puff)  “Hunting for sea glass treasures and safeguarding the hiding places where these precious images of the past wash ashore, are passions among the beach-faithful… This hunger for sea glass is a natural progression… blah…ageless hobby of beachcombing as an anthropological art…blah…this lovely book is a terrific and meaningful gift… blah..those dazzling little pieces of glistening remnants leftover after the sea has abused them as a worthwhile hobby and aesthetic pastime…blah…before being rescued by the beachcombing enthusiast. Holiday gifts, coffee table conversation table toppers or inspirational reading…blah…a book to treasure just like the mysterious particles described between the book jacket covers”

2. The Enthusiast “I love this book. It has a unique perspective – the history of objects from another time – which have washed up on our shores. It is remarkable that a history could be written about a shard of glass. The author manages to trace back through infinitesimal clues the origin and use of what to most is just colorful detrius. The text is very brief and poetic but also informative. The photographs beautifully enhance the found objects. They are insightful and clever, and the quality and sharpness is always first rate”

3. The Pragmatist “I am delighted with this book. Large clear artistic photographs illustrate the research. I have learned a lot about the origins of the beach found objects. To my suprise one of my prized found objects is featured – a Lea & Perrins glass bottle stopper, and I now know it dates from 1876 onwards. I shall be looking out for some purple glass – the rarest colour of all! The text explains why it is so rare. Not a craft book, but a book of answers and interesting facts to inspire the collector”

4. The To-the-Point “Useful purchase beautifully illustrated with creative thought provoking ideas of what can be found on the sea shore and what can be made from what is essentially waste”

And for those that have found glass and want to know what they can do with it, the later companion volume to Sea Glass Chronicles…

A PASSION FOR SEA GLASS

C. S. LAMBERT AMY WILTON

Amazon UK £19.99 new/used about £15

REVIEW CLIPPINGS

“Heaven is sea glass shaped What a wondeful book that transports the reader to a heaven of sea glass images. I thought I was the only weird person, searching the shore line like an oyster catcher, looking for elusive pieces of wave-worn glass and pottery shards. This book shows me there are other like-minded persons who have taken their search to a whole new creative level by fashioning the most beautiful and imaginative pieces of art from their finds”

“Beautiful images  A treasure for any sea glass lover. The images are beautiful and the ideas are creative and inspiring. A wonderfully readable picture book.”

“A fine guide for any art or photography collection Amy A. Wilton provides the stunning photos for A PASSION FOR SEA GLASS, a survey of major sea glass collectors and the workshops of artisans who use the glass to provide everything from sea-glass windows to mosaics, ornaments and more. It complements Lambert’s 2001 SEA GLASS CHRONICLES, which covered collection and identification of sea glass, and adds a new dimension of usage and conversion making this a fine guide for any art or photography collection”

“A worthy sequel to “Sea Glass Chronicles” Author C.S. Lambert and photographer Pat Hanbery showed us the beauty of those colorful beachside finds in “Sea Glass Chronicles: Whispers from the Past.” Now Lambert has gone one step farther by documenting what avid sea glass collectors do with all of their treasures. The people we meet on these pages make jewelry or wind chimes or mobiles. They assemble mosaics on tabletops or walls. One artist crafts panels that look much like stained glass windows, until you examine them more closely. And those are just some of the projects featured in this book. While a few of the profiles include directions for making your own artwork, the focus here is on beauty and art and imagination.”

A must for Sea Glass Lovers I received this book as a gift, and absolutely loved it. I found it interesting to see what other “seaglunkers” did with their collections to display them, where they found their pieces, and enjoyed the beautiful pictures and narrations throughout the book. It is beautifully photographed with great text from the contributing artisans. Terrific craft ideas and suggestions, much more than a tabletop book and well worth the investment”


BOOKCOMBING: AN OCCASIONAL THEMED SERIES (1) OCEAN DEBRIS


BOOKCOMBING

A MISCELLANY OF BOOKS MORE OR LESS RELEVANT TO ABACO LIFE

These are not books I have read myself. They are books that may be of interest to readers of this sort of blog. Islandy. Beachy. Mariney. A whiff of wildlife. They will be collected together under the BOOKS ETC menu as the series expands. If one of them catches your eye, then check online for reviews, reader ratings and prices. If I get round to one or more of them I will add my own views, but I am still gradually working through wildlife books that I have already paid for…

1. FLOTSAM, JETSAM & OCEAN DEBRIS

Flotsametrics and and the Floating World: How One Man’s Obsession With Runaway Sneakers and Rubber Ducks Revolutionized Ocean Science

by Curtis Ebbesmeyer & Eric Scigliano

“Curtis Ebbesmeyer has made important discoveries about everything from currents to the huge floating garbage patches in the ocean to how life was first spread on earth and how the Vikings settled Iceland. In the tradition of John McPhee’s bestselling books on scientists who both study and try to protect the natural world, The Floating World offers a fascinating look at the creativity and energy of a most unusual man—as well as offering an amazing look at what currents have meant for the world and especially mankind through the centuries.  Hardcover; PP: 288; Illustration: 10-15 images throughout” Smithsonian Store

Washed Up: The Curious Journeys of Flotsam and Jetsam

by Skye Moody

“The ocean gives up many prizes, just setting them on our beaches for us to find. From rubber ducks that started out somewhere in Indonesia to land Venice Beach, to an intact refrigerator makes it way to the Jersey Shore. Chunks of beeswax found on the Oregon coast are the packing remnants of 18th century Spanish gold. Author Skye Moody walks the coast, dons her wet suit, and heads out to sea to understand the excellent debris that accrues along the tideline. There she finds advanced military technology applied to locating buried Rolexes, hardcore competitive beachcombing conventions, and isolated beach communities whose residents are like flotsam congregated at the slightest obstacle on the coastline. This book confirms that the world is a mysterious place and that treasure is out there to be found” (Publisher’s Fluff)

Tracking Trash: Flotsam, Jetsam and the Science of Ocean Motion

by Lorree Griffen Burns

“Tracking Trash is the story of Dr. Curtis Ebbesmeyer, an oceanographer who studies the movement of ocean currents. Dr. Ebbesmeyer’s work has attracted attention because he has received much of his information from studying trash. It all began when his mother heard about sneakers that were washing up on a beach after a cargo ship lost one of its containers. Since then, he has tracked sneakers, Lego’s, and even rubber duckies that have been accidentally spilled at sea and made their way to shore. By understanding how ocean currents move, scientists hope to solve many problems such as fish shortages and animals being caught in fishing nets. This book was very enjoyable to read and easy to understand. The pictures were large and engaging. The author did a great job at making it feel like a story while at the same time giving a lot of scientific information” (Satisfied Amazon Punter)

Moby-Duck: The True Story of 28,800 Bath Toys Lost at Sea and of the Beachcombers, Oceanographers, Environmentalists, and Fools who wen in search of them…

Donovan Hohn

I have just spotted that this book is about to be reprinted and, I imagine, updated at the end of February, so I am adding it to the collection. I note in passing that it is published by Penguin…

One 5* review on Amazon UK sets the scene: “This is a book that follows the journey of plastic ducks, turtles, frogs and beavers after the container they are in falls overboard and breaks open on impact with the sea. Moby Duck is fact that reads as good as fiction. The Author doesn’t only traverse the world of escapee plastic toys but meanders his way through a factory in China that makes bath toys, gets on a ship that is on research mission even though he has a fear of open water and even ends in Alaska where the first plastic duck was found. This is a great read, for anyone who likes a quirky book that tells a true story with wit, charm and gentle humour. Moby Dick is never far away in this book, only he has been transformed into Moby Duck…”

Amazon.com has 42 reviews, averaging a disappoining 3.5*. Some are ecstatic, some lukewarm, few can resist the golden opportunity proffered by the author to be “puntastic”. I like the one titled “An Eclectic Tale, but Caught in Its Own Eddy in the End”. Maybe that is the most astute summary of all.

KING VENUS CLAMS & CRAB SHELLS (NO SPACE DEBRIS): ABACO BEACHCOMBING WITH KASIA


ANOTHER STROLL ALONG THE SHORE WITH KASIA

After all the recent excitement – well I was excited, anyway – involving Mars Mission space rocket debris washed up on the Delphi Club Beach CLICK MARS ROVER it’s a gentle touchdown back onto a sandy beach for some more of Kasia’s finds. First, a shell which I believe (tempting fate) I have correctly ID’d for once. Then a half crab shell, at a guess a spider crab’s roof. 

KING VENUS CLAM Verenidae – Chione Paphia

These bivalve molluscs seem to be inoffensive, and to lead rather dull lives: so far all I have discovered is that “they live buried in sand at depths of 1 – 20 fathoms” I shall investigate further & report back – there must be some small creature they molest or upset in some way…

CRAB SHELL, FORMER HOME TO A SPIDER CRAB

BEACHCOMBING ‘CURIOSITY’ ON ABACO: OUT OF THIS WORLD TO THE RED PLANET


Sandy's Mystery Object

More news about the the space rocket debris washed up on the Delphi Club beach, Abaco. The booster rocket fairing found by Sandy fortunately had a serial number on it. Various inquiries have been made and a definitive explanation of the item has now been given by the NTSB. It turns out that the fairing was not, after all, from the Ariane 5 launch in French Guyana. More exciting than that – it comes from a Mars Program launch to put the Space Rover Curiosity on Mars. There’s an excellent Wikipedia article on the mission to be found at WIKIMARS

NTSB - An Independent Federal AgencyBob Swaim at the NTSB has emailed Sandy to say   “The serial number of the fairing fragment is from a part that was on a Delta V [sic – it was in fact an Atlas V, see comments] rocket launch of November 26, 2011. In August, a new car-sized rover will touch down on Mars and you’ll have something from the mission!”  He has kindly provided a link to the launch – see image below and direct link HERE  He has also given a direct link to the NASA MARS PROGRAM site from which I have taken the screen clip below. You will see an image of the Mars Rover Curiosity, and the time countdown until touch-down at the exact moment I took the shot…

I contacted Bill Ailor, Principal Scientist/Engineer, Center for Orbital and Reentry Debris Studies, The Aerospace Corporation AERO CORP thinking a booster fairing might be of interest for their rocket debris database. He writes

Thanks for the notification (and for your excellent web page – looks like a wonderful spot). On the website, we catalog debris that has reentered from orbit and don’t include payload fairings, solid and first stage rocket boosters, and other “range” debris, since these are suborbital and the launch is designed so that the debris impacts is in known safe areas.  That debris can sometimes float outside of the safe area and wash ashore.I should mention that we recently reentered a small device that might one day float to your beach.  I’ve attached a description.  Let us know if you see that one

Although the device he mentions may have in fact have landed a long distance away (the South Pacific even), best keep an eye out for this…REBR Fact Sheet   By a strange coincidence in a huge world, the Aerospace Database shows that in 1965 reentry debris was recovered from a beach on Abaco:

In early 1965 an object having the appearance of a space fragment was reported washed ashore on Abaco Island in the Bahamas Possibly from the Atlas-Mariner I booster which was destroyed by the range safety officer shortly after launch on 22 July 1962, and landed in the designated ocean impact area

Apologies if I have got sidetracked from normal beachcombing duties – shells and stuff – but wildlife blogging doesn’t get more exciting than this – well, unless they find a colony of Abaco parrots on Mars…

‘SO LONG, ARIANE’: FROM ROCKS TO ROCKETS ON THE DELPHI CLUB BEACH, ABACO


STOP PRESS Rocket part now positively ID’d by serial number – and it’s not from Ariane 5. More exciting – it’s from the Mars Program launch of the the Mars Rover ‘Curiosity’. See latest post at  CLICK IMAGE

‘SO LONG, ARIANE’

52 meters / 170 feet, to be precise. The space rocket Ariane 5 is most likely source of Sandy’s mystery object washed up on the Delphi Club beach. See recent post ===>>> SANDY’S MYSTERY OBJECT  for a full explanation. And  here are 2 useful comparative pictures (plus apologies to Leonard Cohen for a feeble pun)

 

ABACO BEACHCOMBING: KASIA IS BACK… WITH ANOTHER MYSTERY OBJECT


Kasia has returned to grace the blog with treasures from her Abaco beach-combing from the Delphi Club and further afield. Expect more shells, more sea glass… and more mystery objects. We have already had part of a RAY’S PALATE and a PACIFIC ANGARIA SHELL  that had somehow arrived on the shores of Abaco. There’s a long thin WHITE BONE, as yet unidentified (no suggestions yet). And now this extraordinary item… 

To which my answer is “not the faintest idea”. My guesses are (1) a fossilised vertebra of some medium-sized creature (2) a fossilised ‘soft’ rock that worms have been at (but why only on one side?) (3) a bread roll that went disastrously wrong in the baking…

All suggestions welcome, preferably via the COMMENT box (so others can view them); or to rollingharbour.delphiATgmail.com (spam guard: convert AT to @)

STOP PRESS Mystery quickly solved, thanks to Colin Redfern who says “This is part of the remains of a colony of Petaloconchus worm-shells (molluscs). They attach to rock or coral, and the colonies can be quite large.”  Colin’s website includes some examples from his archive, one chunk being very similar to Kasia’s
