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.”

GETTING THE MEASURE OF TURTLES ON ABACO

GETTING THE MEASURE OF TURTLES ON ABACO

A recent summer course on Abaco was held in partnership between Elizabeth Whitman (Florida International University) and Friends of the Environment/Frank Kenyon Centre. Participants learned about sea turtle biology and ecology, and discussed potential threats to the vulnerable population. After a classroom session, the team headed out to Snake Cay Creek to carry out a field survey. The turtles caught were measured, weighed, tagged (if not already), and given a general health assessment. Each turtle was then released.

The data captured by such courses is invaluable in the continuing assessment of the health of the local turtle population. In addition, such projects provide a valuable opportunity for people to become involved in a fascinating and rewarding local conservation project – with a literally hands-on experience.

HAWKSBILL TURTLES: A RARE FIND & SWIMMING WITH ANGELS

HAWKSBILL TURTLES: A RARE FIND & SWIMMING WITH ANGELS

There is something unusual about this juvenile hawksbill turtle peacefully noodling round some impressive elkhorn coral with the grunts and sergeant majors. He’s a rarity. He was found at West End, Grand Bahama (just 67 miles swim from West Palm Beach Fl.), a place where hawksbills are very scarce. Loggerheads, they have. And there are plenty of hawksbills elsewhere in Grand Bahama waters. But not at the western tip. So finding this little guy and getting some good photos was a particular pleasure for Linda Cooper. And maybe the presence of a juvenile is a sign that hawksbills may begin to populate the reefs of West End, as perhaps they did historically.Hawksbill turtle (juv), West End Grand Bahama

Linda and her husband Keith run West End Ecology Tours. They have a comprehensive website HERE and a Facebook page HERE. Check it out to see how much there is to explore at West End. The birds, the corals and reef life, the starfish – and a speciality, swimming with rays. To which can now be added the chance of seeing a hawksbill turtle…Hawksbill turtle (juv), West End Grand Bahama

A DOZEN HAWKSBILL FACTS TO CHEW OVER

  • All sea turtles are classed as reptiles (something that always surprises me, somehow)
  • The top shell (carapace) consists of scales that overlap like roof shingles
  • The yellowish bottom shell is called the plastron
  • Adult hawksbills weigh around 100 pounds
  • Sea turtles sleep at night, and can stay underwater for a hours without breathing
  • Hawksbills are omnivorous, eating algae and seagrass but also sponges, urchins and small fish
  • Females lay about 100 eggs like ping-pong balls, and then at once return to the sea for good
  • The sex of baby turtles is determined by relative nest warmth – females from the top eggs
  • Baby turtles hatch almost simultaneously: all must work to dig their way out.
  • They tend to hatch at night and head straight for the sea’s phosphorescence…
  • …except that artificial lights confuse them & lead them away from the sea to likely death
  • Threats: predation, coastal development & habitat destruction, pollution, & illegal collection

SWIMMING WITH ANGELS

As I was writing this, another fact about hawksbills popped into my head. I checked through my archive – mainly Melinda Riger’s wonderful shots from elsewhere on GB – and yes, it is true. There seems to be some sort of symbiotic relationship between the turtles and angelfish. They are often found feeding together. A bit of research confirms this general observation, without giving a clear cause for it. Maybe it is simply that they eat some of the same food; and that there is plenty of it on healthy reefs so there is no cause for aggression on either side. It’s fine for a hawksbill to share with an angel.

NOTE The Hawksbill is listed as Critically Endangered by the IUCN red list of Threatened species as its populations have declined dramatically throughout the world and especially in the Caribbean region. It is listed in Appendix I of the Convention on the InternatIonal Trade of Endangered SpecIes (CITES) meaning that Hawksbills are near extinction or very endangered. All marine turtles are now protected under Bahamian law, as is the taking of eggs.

THE BAHAMAS: A STAMPING GROUND FOR DOLPHINS

THE BAHAMAS: A STAMPING GROUND FOR DOLPHINS

I have commented before on the excellent wildlife stamps produced by the Bahamas Philatelic Bureau, and there is a fairly comprehensive page featuring many of the special issues HERE. Recently, dolphins were treated to their own set of stamps, in conjunction with the BMMRO (Bahamas Marine Mammal Research Organisation).  Four dolphin species are showcased, with a fifth species (Risso’s Dolphin) shown on the commemorative Official First Day Cover (replete with the BMMRO logo). The release date was 31 March 2016.

Bahamas Dolphin Stamps 2016

l_bmmro 25th ann_20160304134635-1

The stamps are available as sets of 4 or of course individually. In a newsletter earlier this year, the BMMRO included some fascinating information about their valuable work – in particular with whales – and about the individual dolphin species featured in this very special philatelic issue. This was also published by the stamp producers, Pobjoy Mint Stamp Division.

BMMRO is a Bahamian non-profit organisation whose mission is to promote the conservation of marine mammals in The Bahamas through scientific research and educational outreach. Since 1991, BMMRO has been conducting small vessel surveys primarily around Abaco Island to document the occurrence, distribution and abundance of marine mammals in The Bahamas.

BOTTLENOSE DOLPHINS Tursiops truncatus

These are the most common marine mammals seen on the Bahama banks. It should be noted, however, that there are at least two distinct “breeding populations” or “ecotypes” of this species: coastal bottlenose dolphins that inhabit the shallow waters of the banks; and oceanic bottlenose dolphins found in pelagic waters. These populations diverged genetically several hundred thousand years ago and have since developed different physiological adaptations to their respective marine environments. The coastal ecotype is smaller in length reaching just over 8 feet and has a relatively larger dorsal fin and pectoral fins which helps them to maneuver more readily around rocks and reefs to catch fish, and to regulate their internal body temperature (the temperature of the shallow Bank waters fluctuates much more than the deeper Atlantic Ocean). The coastal dolphins do not travel much beyond the bank edge and live in small resident communities. The deeper diving oceanic ecotype can reach 10 feet or more in length, are usually seen in larger groups and appear to have a more extensive range with movements documented between Abaco, Bimini and Exuma Sound.

imgres-4

ATLANTIC SPOTTED DOLPHINS Stenella frontalis

These dolphins are not born with spots, but actually accumulate them as they mature, becoming quite mottled-looking as adults. Hence, young spotted dolphins are often confused with bottlenose dolphins, and sometimes the two species will interact, which adds to the confusion. Although they can reach almost the same length as bottlenose dolphins, they have a smaller girth and thus body weight. Atlantic spotted dolphins are a year-round resident species in The Bahamas. Individuals photo-identified 20 years ago in Abaco can still be seen in the same areas today. They are commonly seen in groups of 20-50 dolphins in the oceanic waters where they feed on flying fish and squid, and rarely venture on to the bank. However, along the western edges of Little and Great Bahama Banks this species can regularly be found on the bank during the daytime where they come to rest and socialise.

imgres-5

PANTROPICAL SPOTTED DOLPHINS Stenella attenuata

This species is more slender in body shape than Atlantic spotted dolphins, and also have a distinctive dark dorsal cape, which sweeps from their rostrum to behind their dorsal fin. Like Atlantic spotted dolphins, they accumulate their spots with age, which allows researchers to readily document age-classes within groups. This species is strictly oceanic in its distribution. Pantropical spotted dolphins are not as frequently sighted as Atlantic spotted dolphins in The Bahamas. They occur in groups of 50-100 dolphins and are often seen engaging in acrobatics, such as making high leaps out of the water, and bow-riding.

imgres-6

ROUGH-TOOTHED DOLPHINS Steno bredanensis

These dolphins are dark grey in colour with a long beak and prominent white lips. Their lower jaw and belly can sometimes be a pinkish colour. They reach just over 8 feet in length. They are an oceanic species and although appear to be rare in some parts of The Bahamas, can be regularly seen in the Tongue of the Ocean where they occur year round. Some individuals have been re-sighted in this area over the past ten years. They are typically found in groups of about 20 animals, but are sometimes in larger mixed-species aggregations of several hundred dolphins.

Risso's Dolphin - BMMRONot on a stamp but shown on the First Day Cover

RISSO’S DOLPHIN Grampus griseus

These are large light grey dolphins that can reach over 13 feet in length, and have a relatively tall, dark dorsal fin. Adults are typically covered with overlapping white scars caused by the teeth of their con-specifics making them look quite battered. They have a rounded head, lacking a beak, but have a deep vertical crease down the center of the forehead. As they mature, their forehead becomes prominently white, and as such they are one of the easiest species to recognize at sea. Risso’s dolphins are commonly seen in oceanic waters in the northern Bahamas each winter and spring, primarily on the Atlantic side of the islands. It is unknown where these groups range the rest of the year, but some individuals have been seen off Abaco repeatedly over the years.
