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.

“THE PRINCE OF WHALES”: BLAINVILLE’S BEAKED WHALE

“THE PRINCE OF WHALES”: BLAINVILLE’S BEAKED WHALE

This post results from a recent Technological Breakdown at Rolling Harbour Towers, and is to be viewed as post-trauma therapy. Smart New Mac ordered, to replace 5 year-old warhorse loosely held together with duct tape and prayer. After lengthy (overnight) data migration, Smart New Mac turns out to be faulty. SNM returned to store: a seething hotbed of stress and distress (the shop too). While replacement is eagerly awaited, fry motherboard of old computer with shorted charger. A week of wailing and gnashing of teeth. Smart New Newest Mac brings you this offering.

I like whales. Everyone likes whales. Even whalers, though for very different reasons. Here are some calming pics of one of Abaco’s largest yet best kept secrets – Blainville’s beaked whales. Adults grow to more than 15 feet long and weigh about 2000 pounds, yet they can behave like huge dolphins in slow motion – circling a boat, diving under it, drifting away, swimming back. They have no motherboard and require no data migration.

MANATEE AWARENESS MONTH (& BABY TALK)

MANATEE AWARENESS MONTH (& BABY TALK)

Are you aware of the Bahamas manatees? Just a few years ago your answer might well have been “Bahamas what? No, why? Where?” But suddenly they arrived. And their numbers are increasing. Alternatively, of course, they have always been there, mooching around peacefully and unnoticed in the seagrass.

The Bahamas Marine Mammal Research Organisation BMMRO has been keeping tabs on occasional sightings of manatees in Bahamian waters for some years. But until around 2012 – when I first learned of them and wrote about them – they appeared to be few and far between. They seemed to be unrecorded for Abaco, or anyway unphotographed.** Then the sightings began. Names were given to individuals, identified primarily by distinctive marks or cuts on their ‘paddles’ (tails). Gina. Rita. Georgie. Randy. JJ. Sightings in Hope Town, Little Harbour, Cherokee and the Casuarina canal. Manatees had arrived and were being paid attention. The ease of digital photography and the rapidly increasing use of social media resulted in more reports, wider interest and – yes – greater awareness both on Abaco and elsewhere in the wider Bahamas

**so much for being factually assertive! Many thanks to Mary for her account of one on Green Turtle Cay ‘seen by everyone’; and Kelley for her 2008 one in Galleon Bay canal… of which she actually got a photo…

To give you an idea of the rapid spread of the West-Indian Manatee population, here is a great infographic made recently by Felice Leanne Knowles of the BMMRO, mapping 2016 sightings of both known and unidentified manatees in the Bahamas. An amazing 15 in all, in an area where the natural fresh water these creatures need for survival is in short supply.

You’ll see that in July both Gina and Rita had nosed their way down to Andros. At this time, Gina was known to be heavily pregnant. She gave birth in Kamalame Cay, and the photos of her above with her new calf were taken there.

The baby manatee is known to be a female and there is currently a competition to name her. A spreadsheet-worth of names was submitted to the BMMRO, and they have been whittled down to 3 for a final poll-off between Andie (Andros), Kaman (Kam[alame] An[dros]) and Morgan (Arrrrrrrr in Piratese).

PREHENSILE TALES FROM THE REEF (2): HIPPOCAMPI

PREHENSILE TALES FROM THE REEF (2): HIPPOCAMPI

It is a statistical fact that no one in the world – not even the meanest despot or cruellest tyrant – fails to love seahorses. It would be fair to add that in certain parts of the world, some people love them too much. In more than 65 countries. To the tune of an estimated 150 million a year that are used in the ‘traditional medicine’ trade. An attrition rate that is unsustainable in the long or even the medium term – with the bleak consequence that it won’t be long before people must look elsewhere for their source for Genital Tonic Pills. 

Seahorse (Adam Rees / Scuba Works)Seahorse (Adam Rees / Scuba Works)

Medicinal use – of empirically vague benefit to its enthusiasts – is joined by the aquarium trade in accounting for the removal of very large numbers of seahorses from their accustomed surroundings. At least these creatures live on (rather than being dried out alive), though research suggests that the survival rate of seahorses in captivity is low. 

Seahorse (Adam Rees / Scuba Works)

Do you sometimes hanker for a plastic brooch or paperweight with a tiny seahorse embalmed inside it? It would be good to resist the temptation to buy such things in seaside shops or online. Your little specimen will be one of a million or so souvenir seahorses sold each year, alongside seashells, starfish, sponges and (protected) corals. 

Seahorse (Adam Rees / Scuba Works)

As you contemplate your purchase, you may be reassured to find that the product is labelled ‘environmentally friendly’, ‘responsibly sourced’ or ‘from a sustainable source’. You can make up your own: ‘lovingly harvested from the bluest oceans’, maybe. In the words of the SEAHORSE TRUST: 

“Nothing could be further from the truth; there is nothing sustainable about this exploitation of the seas. You can make change by not buying them. If there was no market there would be no trade.”

FAIRY BASSLET (‘MIND YOUR GRAMMA’): BAHAMAS REEF FISH (33)

FAIRY BASSLET (‘MIND YOUR GRAMMA’): BAHAMAS REEF FISH (33)

The Fairy Basslet is a tiny brightly-coloured fish with a pretentious alternative name. It is otherwise known as the Royal Gramma (Gramma loreto). These fish are found  in the coral reefs of the (sub)tropical western Atlantic. They are also found in aquariums anywhere you like, being small, bright, placid and generally good-natured.

fairy-basslet-melinda-riger-gb-scuba

Conveniently, the basslet is unlikely to be confused with any other species. Its striking two-tone colour scheme of purple and yellow is hard to miss. The purple front half (which is presumably where the ‘royal’ comes from, being a regal or imperial colour) may also be violet or even blue in some fish and / or in some light conditions. Another identification pointer is a black spot on the dorsal fin. 

fairy-basslet-melinda-riger-grand-bahama-scuba

You’ll notice that the basslet above appears to be upside down. Which is because it is – this isn’t an inadvertent photo-flip. These little fish tend to orientate themselves to be parallel with the closest surface. This leads to them happily swimming upside down, or aligning vertically. As one article I read says severely, “this behaviour is not to be mistaken for illness”.

fairy-basslet-melinda-riger-g-b-scuba

Fairy basslets / royal grammas are also CLEANER FISH. They pick parasites and dead skin off larger fish that visit so-called cleaning stations to be attended to by tiny fish and cleaner shrimps, and in some instances to have their gills and even their teeth cleaned. The deal is that, in return, the large fish do not eat the cleaners. Even snack-sized ones rootling around inside their mouths.

fairy-basslet-melinda-riger-gb-scuba

 WHAT ABOUT BREEDING?
I really can’t improve on this rather touching description from Wiki: “The male will build the nest among rocks using pieces of algae. The male will then lead the female to the nest, where she will deposit 20-100 eggs in the nest. During the breeding period, this behaviour is repeated almost every day for a month or longer (my italics). The eggs are equipped with small protuberances over the surface with tiny threads extending from them which hold onto the algae of the nest and keep the eggs in place. The eggs will hatch in five to seven days, normally in the evening…”

HOW COME THE NAME ‘GRAMMA LORETO’?

This official name became a brainworm with me after I started this post. I had to check it out. The ‘Gramma’ part is unrelated to the fond name for a grandmother; rather, it simple denotes a member of the genus of fishes in the family Grammatidae.

The Loreto part is more mysterious. It is an an ancient town in Italy; and the name of several British schools, including – almost too good to be true – a school called Loreto Grammar. In a nutshell, the link between the town and places of education is that the Sisters of Loreto, founded in the c17 and named for a shrine in the Italian village, are dedicated to education in their Ministry.

How that ties in with a tiny Caribbean reef fish, I have yet to find out. I probably never will… Here’s a short video to alleviate the disappointment.

I failed to be able to resist finding out whether any country of the world has a purple and yellow flag. The answer is, no. However I am delighted to be able to report that the flag of the Independent Party of Uruguay is basslet-coloured.

SILVERSIDES: BAHAMAS REEF FISH (32)


silversides-school-melinda-riger-g-b-scuba

SILVERSIDES: BAHAMAS REEF FISH (32)

I have no idea if there is a collective noun for a large group of silversides. ‘Frenzy’ would cover it, but that is reminiscent of ‘feeding freezing’ which has a specialist meaning – and anyway, silversides are crazy even when they aren’t feeding. 24/7/12/365 as far as I can make out. I think ‘a panic of silversides’ might be the answer. They are just… all over the place at high speed. Sometimes swirling around pointlessly, other times moving in unison and suddenly all changing direction simultaneously, like a single creature made of tiny shards of silver.

silversides-school-melinda-riger-g-b-scuba-copyfish-frenzy-melinda-riger-gbs

There are quite a few silverside species around the world. The ones in the Bahamas are Atlantic silversides (Menidia menidia), also known in the north east of the United States as ‘spearing’. They seem to exist for two purposes. The main one is to be breakfast, lunch or dinner for larger fish, sea birds and shore birds. The other is for their usefulness in scientific research because of their sensitivity to environmental changes. 

silversides-melinda-riger-g-b-scuba-copy-2silversides-school-melinda-riger-gb-scuba

In one sense they are easy prey for predators. A determined fish will always manage a snack by swimming into the middle of a panic and (probably) simply by opening its mouth wide. On the other hand, their sheer numbers coupled with the speed and randomness of movement mean that a single may find a degree of safety in numbers. It’s hard for a predator to target any individual fish in the general melee and confusion. Silversides also favour seagrass beds, which give some shelter and protection – and a reasonably safe place to spawn. Or, as some of these photos show, they will hang around wrecks or squeeze into rocky spaces in the reef.

WHAT DOES A STATIONARY ATLANTIC SILVERSIDE LOOK LIKE?

meber_u0

Some time ago we used to go to the reef at Fowl Cay Marine Preserve with Kay Politano, and I would snorkel with a small and very basic lo-res underwater camera. I was hampered by being a disgracefully feeble swimmer; by not having snorkelled for a length of time calculable in decades; and by being a complete novice at underwater photography.  Despite these not inconsiderable disadvantages I managed to cobble together a few short movies on my computer (I was new to that too). Here’s one that nearly works, in that it gives an idea of what happens if you ‘swim with silversides’. I know you scuba guys all swim with sharks, but cut me some slack here please…

HAMMERHEAD SHARKS: UP CLOSE AND PERSONAL…


Great Hammerhead Shark, Bimini (Grant Johnson / 60 Pound Bullet)

HAMMERHEAD SHARKS: UP CLOSE AND PERSONAL…

Of all the words that have been devalued and diminished by overuse over the last decade, ‘AWESOME!!!’ must rank high in the top 10. Maybe it’s even made it to number 1. Awesome! Even in the wildest reaches of hyperbole, the offer of a Kalik can never truly be awesome. Nor can a kind and delightful gift. There’s no need to add more examples, because the photos that follow show something that really is awesome in it’s true meaning: the giant hammerhead shark at close – and very close – quarters. Grant Johnson takes astounding wildlife photos in Bimini and far beyond. Take the time to have a look at his page ’60 POUND BULLET’. Now let’s move on to ‘awesomely awesome…’

And yes, there are Hammerheads in Abaco waters. I have occasionally seen small- to medium-sized ones while fishing out on the Marls. In several of the images above, you can see those strange creatures, Remoras, that attach themselves to sharks by suction and hitch a ride. You can read more about them and learn why they do such a foolish thing HERE
