LAURA JESSON “Do you know, I believe we should all behave quite differently if we lived in a warm, sunny climate all the time. We shouldn’t be so withdrawn and shy and difficult…” (Brief Encounter 1945)
The quote is there both because it is particularly apposite for any withdrawn etc Brit with a toehold in Abaco, and because it explains or excuses the somewhat clumsy title pun… March has been dominated by (a) a trip to Abaco and (b) publication of “The Birds of Abaco”. Time for some cheerful finny fotos to end the month with, courtesy of diving belle Melinda Riger of Grand Bahama Scuba and her top-class camera work.
BAHAMAS REEF FISH (14): HAMLETS (NOT GLOOMY DANES)
“Oh, that this too too solid flesh would melt, thaw and…” Ah! Sorry. I’m soliloquising again. Must be Thursday. And the merest mention of Hamlet is enough to set anyone off. But I speak not of noble yet gloomy Danes of Elsinore and of discernibly introspective aspect. These ones are pretty reef fish of the Caribbean seas, mainly in the Bahamas and along the Florida coast. There are a number of different types of hamlet, of which the 4 featured below in Melinda’s amazing underwater images were were encountered in one dive.
SHY (OR GOLDEN) HAMLET
Hamlets have outstandingly interesting reproductive skills, being ‘synchronous hermaphrodites’. They have the unusual benefit of having both male and female sexual organs as adults, permitting imaginative combinations of pairings (though not including self-fertilization). When they find a mate, “the pair takes turns between which one acts as the male and which acts as the female through multiple matings, usually over the course of several nights”.I don’t dare check whether there are websites that cater for this sort of energetic coupling. The wonder is that Hamlets preferentially mate with individuals of their same colour pattern, and that they are not more wanton with their attentions and sexual flexibility.
OPTIONAL CULTURAL, HISTORICAL & MUSICAL DIVERSION INSPIRED BY HAMLET
The other notable Hamlet is, of course, the mild cigar equated in the famed commercials with happiness, accompanied by an excerpt from a jazzy version of Bach’s ‘Air on the G String’. Here is one of the best – and possibly the only advert to my knowledge to feature not one, but two excellent Sir Walter Raleigh jokes.
Bach’s well-known descending chord sequence of was of course shamelessly ripped off by ingeniously adapted by Procol Harum for ‘A Whiter Shade of Pale’, their first single in 1967. Relive the Summer of Love right here and now. Is this the music that might even put those versatile hamlets in the mood…
Any fret-tweakers might like to see the sheet music of the Air for guitar – you could even play it on air guitar – which is relatively easy, being in C major.Credits: All fish pics Melinda Riger of Grand Bahama Scuba, except wiki-header; open-source online material; my mp3, dammit – I can’t get the wretched tune out of my mind…
UNDERWATER REEF GARDENS IN THE BAHAMAS (2): CORALS
This is part 2 of a series that started out HEREwith a selection of anemones, basket stars and Christmas tree worms. The images below show a wide variety of corals. In among them are also sponges and anemones. These photos are evidence of a healthy reef environment in the waters of the northern Bahamas. Abaco’s coral reef is the third largest barrier reef in the world (yes, I hear you – the Great Barrier… And the second is???), providing wonderful and accessible diving / snorkelling opportunities. However, monitoring shows that the incidence of coral bleaching and disease is increasing in the Bahamas, as elsewhere in the world. It’s a sobering thought that your grandchildren may never swim in an environment with any of the living corals shown below…
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.
GRAY ANGELFISH (Pomacanthus arcuatus) BAHAMAS REEF FISH (3)
I recently posted about the highly colouredQUEEN ANGELFISH, a striking coral reef resident glowing with fluorescent blues and yellows. It’s the Angelfish that went into showbiz and succeeded. Its close cousin the Gray Angelfish is a more sedate creature, with the appearance of a professional – law, possibly, or medicine. That thin blue fin-edging suggests a flamboyant streak. Slightly mean mouth? Lawyer.**
This species is found in the warm waters of Florida, and south through the Bahamas and Caribbean as far as Brazil. They are found at depths from 2 m. down to 30 m. You are most likely to encounter one on a coral reef feeding on sponges, its main diet. The fish below with the bluer face is a teenager, in transition between juvenile and adult.
SPOTTED DRUM FISH Equetus punctatusBAHAMAS REEF FISH(1)
This post is the first of a planned series on Bahamian reef fish. Those who follow this blog (I thank you both) may recall with horror (or worse, pity) my own efforts with reef fish, using a tiny cellphone-sized video camera. Misty stills culled from video footage. Enthusiastically wobbly movies as I struggle to swim and breathe simultaneously in an alien element. I am more underwater CLOUSEAU thanCOUSTEAU. However, thanks to Melinda Riger, who with husband Fred runsGRAND BAHAMA SCUBA, I have kind permission to borrow and display images from her stock of wonderful reef fish photographs.
The spotted drum fish (related to two other Caribbean drumfish, the High-Hat and the Jack-knife fish) belongs to a large worldwide family, the Sciaenidae. Besides other drum varieties, the family includes ‘croakers’. These species are all named for the repetitive throbbing or drumming sounds they make. This involves the fish beating its abdominal muscles against its swim bladder. If I find out the reason for this (Species communication? Food call? Alarm? Warning? A piscine ‘advance’? Happiness?) I will add it here in due course. Here an example of an atlantic croaker from the excellent DOSITS site (Discovery of Sounds in the Sea)
The spotted drum is one of the few fish of the species to inhabit coral reefs – most are bottom-dwellers (often in estuaries), avoiding clear water. These fish tend to be nocturnal feeders, feeding on small crabs, shrimp and small invertebrates. As far as I can make out they are solely (or primarily) carnivore, and do not graze on algae of other reef plant life.
The photos above are of adult spotted drums. The ones below are of juveniles, and show the remarkable growth-pattern of these fish, from the fragile slender creature in the top image, through the intermediate phase of the one below it (with the amazing brain coral), to the striking adult versions above. People like to keep these pretty fish in aquariums; fine, I’m sure there are plenty to go round, but these ones look pretty happy to me in their natural reef environment…

Finally, I’ve just come across this short video from a “Florida Aquarium”, showing how these fish swim. It rather looks as though it has been fin-clipped for some reason… or just damaged, maybe
