AN OCTOPUS’S GARDEN, BAHAMAS

AN OCTOPUS’S GARDEN, BAHAMAS

Many of us, from time to time, might like to be under the sea, warm below the storm, swimming about the coral that lies beneath the ocean waves. Though possibly not resting their heads on the seabed. This undeniably idyllic experience would be perfected by the presence of an octopus and the notional garden he lives in. Enough to make any person shout and swim about – and quite excessively at that.

The extra ingredient here is that these photographs were taken on the reef off the southern coast of Grand Bahama last week, less than 2 months after the island (along with Abaco) was smashed up by Hurricane Dorian. Thankfully, Grand Bahama Scuba has been able to return to relative normality and run diving trips again. Moreover, fears for the reefs have proved relatively unfounded. These images suggest little damage from the massive storm. The Abaco reefs have not yet been able to be assessed in any detail.

The feature creature here was observed and photographed as it took it a octopodic wander round the reef. The vivid small fishes are out and about. The reef and its static (technically ‘sessile’) life forms – corals, anemones and sponges – look in good order. The octopus takes a pause to assess its surroundings before moving on to another part of the reef.

THE PLURAL(S) OF OCTOPUS REVISITED

A long time ago I wrote a quasi-learned disquisition on the correct plural for the octopus. There were at least 3 possibilities derived from Greek and Latin, all arguable but none so sensible or normal-sounding as ‘octopuses‘. The other 2 are octopi and octopodes. If you want the bother with the details check out THE PLURAL OF OCTOPUS.

There’s an aspect I missed then, through rank ignorance I’d say: I didn’t check the details of the Scientific Classification. Now that I am more ‘Linnaeus-woke’, I have two further plural candidates with impeccable credentials. Octopuses are cephalpods (‘headfeet’) of the Order Octopoda and the Family Octopodidae. These names have existed since naturalist GEORGES CUVIER (he of the beaked whale found in Bahamas waters) classified them thus in 1797.

RH ADVICE stick with ‘octopuses’ and (a) you won’t be wrong (b) you won’t get into an un-winnable argument with a pedant and (3) you won’t sound pretentious

OPTIONAL MUSICAL DIGRESSION

Whether you are 9 or 90, you can never have too much of this one. If you are somewhere in the middle – or having Ringo Starr free-styling vocals doesn’t appeal – you can. Step back from the vid.

‘SLOW BLUES IN SEA’: BAHAMAS REEF FISH (10)

‘SLOW BLUES IN SEA’: BAHAMAS REEF FISH (10)

Albert King, Lead Belly and Mike Bloomfield are prime examples of foremost bluesmen guitar-slingers who, in their own distinctive styles, favoured the key of… I’m sorry, what did you say? Oh yes, quite right. My misunderstanding. Apologies, I’ll take it from the top…

Deep blue sea. Deep blue fish. *Deep breath*. All better now. The fish below may all readily be found nosing around the coral reefs of the Bahamas in a leisurely manner. Mostly, they are feeding. Fowl Cay Marine Preserve, Abaco, is a great place for watching them. No need to have all the gear – a simple snorkel, mask and flippers, and an ability to float a bit, would be sufficient.

BLUE CHROMIS Chromis cyanea

These dazzling little blue fish will be one of the first you’ll meet (along with the omnipresent yellow and black striped sergeant majors, so friendly they will come right up to your mask). You can’t miss them. Though very small, their electric blue colouring cuts through the water even on the dullest of days up-top. They can reach 5 inches in length, but most that you see will be tiddlers. They are frequently seen in the company of larger fish.

BLUE PARROTFISH Scarus coeruleus

Parrotfish play a vital part in the ecology and health of the coral reef. They graze on algae, cleaning the coral and grinding the surface with their teeth. They take the nutrients and excrete the rest as… sand. This helps to form your beach! To find out more about their uses and habits, click PARROTFISH. You’ll find a great deal of interesting info about the species, conveniently compressed into factual bullet points.

BLUE TANG Acanthurus coeruleus

The blue tang is a type of surgeonfish, all-blue except for a yellow spot near the tail. The blueness can vary considerably, from very pale to dark. They tend to swim elegantly around in large groups.

Here are some images of schools of blue tang that I took with a cheapo underwater camera at Fowl Cay. They are a lovely sight as they drift slowly past alongside the reef. The top one also has a sergeant major (see above).

CREOLE WRASSE Clepticus parrae

This wrasse can grow up to a foot long, and may be found at considerable depths on deep-water reefs – 300 feet or more. They are active by day, and hide in rock clefts at night. This species is sociable, moving around in shoals. They develop yellow markings with age.

QUEEN TRIGGERFISH Balistes vetula

There are several species of triggerfish. The queen is capable of changing colour to match its surroundings, or (it is said) if subjected to stress. I think we have all been there. It is an aggressive and territorial fish, and its favourite prey is the sea urchin, a testament to its courage…

QUEEN ANGELFISH (JUVENILE)

I have featured this species before HERE, and strictly it as much yellow as blue. But the blue earns double points, surely, for its startling vividness. Anyway, I like the way it hangs casually upside down, and the bubbles in this photo.

From time to time I end a post with something musical. Just for fun (toxic concept). So here is a real “Slow Blues in C” from the fantastic guitarist Stefan Grossman off his eclectic ‘Yazoo Basin Boogie’ album. 22 quality tracks. Buy from Am*z*n – much cheaper than iT*nes.

WEST INDIAN MANATEES AND THE BAHAMAS: THE FACTS

January 27, 2012 by Rolling Harbour

WEST INDIAN MANATEES IN THE BAHAMAS

The appearance of a mother and calf manatee off the Berry Islands in December 2011 – see BMMRO SIGHTINGS post – led me to investigate these creatures a bit more. I added some more info and a couple of photos to that post, but really they deserve a post in their own right. So, with a wave of a flipper in the direction of Wiki and other open sources, here’s some more about these most strange-looking mammals, just in case you ever happen to come across one…

I will expand the post when I have read the latest “What Manatee?”, “Total Manatee” and “Manatee Monthly” magazines

MANATEES Trichechidae “Large, fully aquatic, mostly herbivorous marine mammals. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia. The name manatí comes from the Taíno, a pre-Columbian people of the Caribbean, meaning breast”

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 (see below for the THREATS to the species)

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

PREDATION, THREATS AND CONSERVATION – A SUMMARY The manatee is yet another creature whose worst enemy is mankind. The generalisations below apply to the West Indian manatee – elsewhere there may be different problems

Natural predators Manatees have few natural predators except, occasionally, sharks and crocodiles. Predation is not a significant survival threat. The main causes of death are human-related, such as habitat destruction and human marine objects; and natural causes such as low water temperature and disease

Hunting Historically, manatees were hunted for meat. They were easy to tempt to a canoe and then stun with a pole. Manatee hides were used – and traded – for canoes and shoes; their bones were used for ‘medicine’. Museums used to pay for hides or bones. Hunting was banned in 1893, though some poaching still occurs

Manatee Group Young Manatee

Ship-strike Manatees move slowly and are curious… Coastal development has led to many violent collisions with propeller-driven boats and ships, causing maiming, disfigurement, and death. Manatees are cut in half by large vessels like ships and tugs. Many others have propeller scars and they can often be identified by their scar patterns – some bear 50 scars and disfigurements from vessel strikes. Breeding ability may be affected. Infected injuries can prove fatal. Internal injuries also come from being trapped between hulls and docks. Studies of the attrition rate from “boat mortality” alone is causing much concern for the survival of the species. In 2009, of 429 Florida manatees recorded dead, 97 (23%) were killed by commercial and recreational vessels

Red tide Another cause of manatee deaths is “red tide”, blooms of the microscopic marine algae Karenia Brevis. This produces toxins that affect the central nervous systems of sea creatures. In 1996 an outbreak off the Florida coast killed 151 manatees

Other threats (1) Fishing gear: hooks, metal weights, and especially mono-filament line clogging a manatee’s digestive system; entanglement in fishing lines (2) water-control structures such as navigation locks and floodgates (3) drowning in pipes and culverts (4) bizarrely, there have been numerous reports people, when allowed to swim with manatees in Florida, harassing them

CONSERVATION All three species of manatee are listed by the World Conservation Union as vulnerable to extinction. It is illegal under US federal and Florida law to injure or harm a manatee. They are classified as endangered by both the US state and the federal governments. Some vessels are now adapted to help prevent harm to manatees where they operate

EXPLORING CORAL REEFS: FOWL CAY MARINE PRESERVE, ABACO

January 19, 2012 by Rolling Harbour

EXPLORING THE CORAL REEF AT FOWL CAY MARINE PRESERVE, ABACO

First, a warning for anyone arriving new to this blog (hi! welcome) either on purpose or accidentally: I can’t swim very well, I hadn’t snorkelled for decades until last year, and I’d never before used a camera underwater.

That said, there is probably enough in this 2:40 min video to warrant a quick view. As with other videos from this expedition to Fowl Cay Marine Preserve (STINGRAY / BLUE TANG), best viewed small to avoid queasiness and disorientation. You can always Pause for a breather. There are some nice fish obligingly in view from time to time, and the coral is very diverse. And I’ll know what to do this year to get better results, besides trying harder with the swimming… (Music: East Wes by Eric Johnson, off Ah Via Musicom)

STINGRAY AT FOWL CAY MARINE PRESERVE ABACO

October 8, 2011 by Rolling Harbour

A while ago, I posted stills from a reef-snorkelling video – my first ever underwater video attempt, and indeed my first snorkel for about 40 years CLICK===>>> REEF FISH I started with a stingray, producing some rather… ok, very… modest results, but it was at least identifiable if you looked carefully and felt benign.

I’ve learned a few tricks since then. Here is the whole clip, still hopeless in most respects but there’s something quite cute about the creature. Mercifully it is only 37 seconds long. I reserve the right to delete this post when I realise no one has actually watched it! [LATER: Oh! I find a few hardy souls have done so. It’s a democratic vote for the ray to stay, as I see it]

[Belated credit to the fairly litigious Joe Satriani (see JS v Coldplay 2009) for borrowing the intro to one of his songs. It’s a non-commercial tribute, Joe]

REEF FISH & PREDATORY PARROT FISH – MORE FROM FOWL CAY ABACO

Here are some more stills of reef fish taken from the video of our reef-snorkelling trip to Fowl Key with Abaco Above and Below. I’ll add the fish IDs gradually. The first batch are images of individual fish; the second batch is a sequence showing a queen parrot fish feeding on small fish (?gobies) – images that I’d expect David Attenborough to describe in his quiet and breathy way as “really quite extraordinary”, especially if he has seen the general standard of pics in this blog…

REEF SNORKELLING AT FOWL CAY MARINE PRESERVE, ABACO

June 8, 2011 by Rolling Harbour

You will need: swimming kit; sweatshirt (it can be cold on the boat after snorkelling); stuff for Island Hopping later on, inc. camera, money etc; snorkel practice in the pool if you haven’t used one for (say) 20+ years – use the Club gear; Ian Took’s slim ‘Fishes of the Caribbean Reefs’. NB there is limited room on the boat, so you’ll need a bit of a nifty towel work to preserve modesty when changing…

Kay Politano of Abaco Above and Below in Marsh Harbour pencils in an unspecified number of places for a day’s island-hopping and reef-snorkelling while I find out how many non-fishing-that-day Delphi guests might be interested. Seven sign up, and one morning we all set off to Marsh Harbour. In Kay’s shop we try on our flippers, marvel at the scuba possibilities (a completely implausible proposition for most of us…), then we troop off to the marina and Kay’s reassuringly powerful and safe-looking catamaran. It takes 12 passengers; the other 5 are already aboard. We set off towards a threatening-looking weather front; rain later is a certainty…

Kay and rh at the controls

Passing by several Cays, we arrive at Fowl Cay Marine Preserve and drop anchor. We don our flippers, wrestle with our masks and snorkels, and in turn drop off the back of the boat (ok, stern, is it?) into warmish water, under thick grey cloud. My practice in the Delphi pool has paid off, and soon I am wheezing and gurgling my way towards the reef with my head (mostly) under water, a situation I generally avoid.

I am completely unprepared for what I find when I get to the reef. David Attenborough’s favourite production team has kindly arranged for a wide variety of bright fish, some electrically charged, to come up close and inspect me, an intruder in their world. I’ll spare you the colour-supp superlatives and graphic intensifiers – you’re probably blasé and have seen it all before – but I am totally gobsmacked, even with my mouthpiece in place. It’s all real! It’s even better than TV! And don’t get me started on the coral…

Parrot Fish

Blue Tang / Ocean Surgeonfish

Blue Chromis

Sting Ray

While I gasp and bubble my way around, I keep a small waterproof video camera running (see GADGETS review). My swimming is feeble at the best of times, but somehow it all seems to be coming together – my flailing limbs, the laboured breathing, the reef, the fish and the footage. We circle round the reef – occasional pale figures appear in my lateral vision – for about 25 minutes, then return to the boat and the struggle to remove our flippers…
Everyone is excited about what they have seen (some saw barracudas). Who cares that it’s started drizzling… we are wet already and it’s off to Lubbers Cay for lunch; see forthcoming Island-Hopping Post. And see MARINE LIFE page for more reef fish photos taken on this expedition.

ADDITION April 2012 I notice there have been a few specific searches ‘what is the plural of Sergeant Major?’ Good question. The strict grammatically correct answer is, I suspect (as with the military rank), ‘sergeants major’ because it’s the sergeants who are plural and the ‘major’ is a qualifier to distinguish from other degrees of sergeant (were there sergeants minor, for example). It’s the same with courts martial – not ‘court martials’. BUT it sounds all wrong and pernickety. I reckon the whole fish is a sergeant major. If there are 2 or more, you’ve got some sergeant majors to play with.
