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.

FLORAL CORAL: REEF GARDENS IN THE BAHAMAS

FLORAL CORAL: REEF GARDENS IN THE BAHAMAS

Like many of the blues musicians who covered Robert Johnson’s originals, we got ramblin’ on our minds. Specifically to ‘Delphi East’ in Ireland, thus stupidly exchanging 82F sunshine in southern UK for 46F rain in the Emerald Isle. Good for the fishing, if nothing else… So (always remembering that corals are actually creatures and not plants) here’s a bouquet of coral to be going on with until we next meet with wifi!

OPTIONAL MUSICAL RAMBLING

Robert Johnson’s output – a meagre 29 songs in all – formed the bedrock for later bluesmen and the blues / rock crossovers that followed. They mined Johnson’s talent and formed their own new material from it. Here’s the original – you’ve probably heard it or variations of it with different names, a thousand times – some good, some bad, most so-so.

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

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

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.

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.

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.

CHEROKEE SHELL MUSEUM, ABACO: “GIFTS FROM THE SEA”

CHEROKEE SHELL MUSEUM, ABACO: “GIFTS FROM THE SEA”

One of the smallest museums in the world has just opened on April 15 in the picturesque settlement of Cherokee on Abaco, Bahamas. Other contenders for the title include the MmuseumM in New York, housed in an elevator shaft (look through glass window + audio guide); a converted red telephone kiosk in Warley, Yorkshire UK dedicated to local history (one visitor at a time); and a tiny shed of 134 sq ft in Arizona featuring what might broadly be called ‘ephemera’, including a Beatles poster…

Whatever the size comparisons, the new shell museum is beyond doubt the very best one in the Bahamas, not least because it is the only one. “Gifts from the Sea” is housed in the former 1950s telegraph office that ceased to operate in 1987 and had fallen into disrepair. Leased from BTC for a nominal rent, the little building was restored, and given a smart new roof and a complete makeover. The new museum provides the perfect space for displaying a selection of the wonderful shells to be found in Abaco waters.

The whole community has got behind this project, which is the vision and creation of Curator Lee Pinder. Derek Weatherford fitted cabinets for the exhibits, and artist Jo-Ann Bradley has painted a fabulous interior Cherokee-themed mural as a fitting backdrop to the displays.

The exhibition shows more than 200 shells, each catalogued with its Latin and common name, and clearly labelled in the display. Most were found locally; a few are from further afield. Some specimens are very rare. It is hoped to expand the collection as people make shell donations to the museum.

The building has a door at each end to give natural light and provide a ‘walk-through’ arrangement, which will make viewing in the confined space easier. Entry is free but there’s a glass jar for donations towards the upkeep of the museum. I’m guessing here, but I reckon donations that are made ‘outside the jar’ (so to speak) are very welcome too…

The opening ceremony took place on Easter Saturday, when Cherokee resident Rev. Bateman Sands performed the official ribbon cutting ceremony preceded by a prayer at precisely 12 noon. As Jennifer Hudson in an Abaconian article points out, he was the ideal person for the task, having been “the first telegraph operator in Cherokee Sound, working in the little building using Morse code and in charge of the one and only telephone in the settlement until 1987 when the new BTC building was opened”.

The shell museum is not left open all the time, but visitors are welcomed and private tours can be arranged by calling 475-7868.

FLORAL CORAL: BEAUTIFUL BAHAMIAN REEF LIFE

This post needs no commentary from me, nor my larky intrusions. These wonderful images from Melinda Riger speak for themselves. You’ll see a wide variety of soft and hard corals in the images below (prize** for the full list). If these superb photos don’t want to make you want to grab a snorkel, mask and flippers, then… well, that would be a very great shame.

SPONGES ON THE REEF: A COLOURFUL MISCELLANY

It’s time to take an up-close look at some of the sponges you may find as you snorkel or scuba round the reefs of the Bahamas. I am always amazed by how bright and colourful they are, and by their many different shapes and sizes. Even the unpromising sounding (slightly medical, even?) BROWN TUBE SPONGE turns out to be fascinating to examine closely. Here are some more sponge species.

The above sponges represent a fraction of the sponge varieties found on Bahamas reefs. I’ll post some more quite soon. All this has made me want to go for a snorkel. But right now I am 30 miles from the sea. And I have no gear…

HANG ON A MOMENT! WHAT IS A SPONGE WHEN IT’S AT HOME?

It’s really very simple: if you are ever asked the question, just reply “a sponge is a primitive sedentary aquatic invertebrate with a soft porous body that is typically supported by a framework of fibres or calcareous or glassy spicules. Sponges draw in a current of water to extract nutrients and oxygen”.

AND WHAT, PRAY, IS A SPICULE?

You’re having a laugh… if you seriously want to know, read the abbreviated version about them HERE. And admire this microscopic collage of ‘demospongiae spicule diversity’ made available by the wonders of Wiki and the research of about 20 credited scientists.
