‘ELEGANTLY WEIRD’ – SPOTTED DRUMFISH JUVENILES: BAHAMAS REEF FISH 20


‘ELEGANTLY WEIRD’ – SPOTTED DRUMFISH JUVENILES: BAHAMAS REEF FISH 20

I’ve posted before about the rather extraordinary SPOTTED DRUMFISH, one of those reef fish which in juvenile form is very different from the adult. This species was first up in the Bahamas Reef Fish series – click above link. Here are a few recent images, courtesy of Melinda Riger. The first three show the juvenile form (note the piscine photobomb in the first one). The last shows a group of adults hanging out on the reef with (I think) some soldierfish. You can see how the juvenile drumfish becomes the adult, but those little stripy bullet-heads with their two long elegantly trailing appendages differ considerably from the rather solid-looking spotty / stripy adults with their dramatic punko-rockabilly quiffs.

CETACEAN SENSATION: SPERM WHALES & DOLPHINS ON ABACO

July has been ‘Whale Camp’ month for the BMMRO, when a small group of lucky youngsters get to spend time out at sea searching for whales and dolphins, and learning the intricacies of data recording and research. One target was the sperm whale, a species that may be found off the coasts of South Abaco. This is a favoured place because the deep trench of the Great Bahama Canyon throws up the food these whales need (see map below).

After some time spent searching, the BMMRO reported  “the sperm whales are back! We found a single animal yesterday, and finally in the evening found the rest of the group, 10+ animals including 3 mother-calf pairs, and dolphins at Rocky Point!” Here are some of the photos from the trip.

This map of the northern Bahamas shows the V-shaped tails of the Great Bahama Canyon, and explains why the east coast and (in particular) the shallower south-west coast between Hole-in-the-Wall and Rocky Point is so attractive to feeding whale species.

The dolphins were quite prolific in July, in particular bottlenose and spotted dolphins. These photos were mostly taken while the search for sperm whales was going on: the BMMRO posted “lots of dolphins up at Gorda Cay yesterday… still not hearing any sperm whales in the area, has been a couple of weeks without sign of them so they should be showing up again soon…” As they obligingly did!

Today is the first day of the crawfish season and Facebook Abaco has been crawling with crawfish for a couple of days in feverish anticipation. So I decided to stick with whales and dolphins instead because there are enough crawfish images out there to keep anyone happy. However I did particularly like this offering today from Albury’s Ferry Services, always a byword for tastefulness and decorum. I’ve borrowed their picture (they borrow mine sometimes) – I wondered if it need a little more exposure, then decided there was probably quite enough already….

Few people know that, by international law, it is unlawful to fail to be fascinated by Octopuses… Octopi… Octopodes… Octopotomi… Whatever. For a learned dissertation on the correct plural form for these creatures – bear with me, there are strict rules that apply here – you’ll find out the right way at THE PLURAL OF OCTOPUS I won’t go into it all now, because it’s time to showcase some more wonderful underwater photography by Melinda Riger of Grand Bahama Scuba. Strictly, these are not Abacos Octos, but they share the same reef system and are therefore close cousins. Of such tenuous links are blog posts formed.

The Rare Scottish Tartan Octopus

Bagpipe

SAD POST SCRIPT:  As a Scot out of Norway (did you ever?) my father learnt to play the bagpipes. Indeed had a set. They lived in a cellar I wasn’t allowed into. The bag was allegedly preserved in treacle (don’t ask). I still have the ‘Chanter’ (a single pipe practice instrument), the sound of which is akin to trying to strangle one cat with another cat. I was fobbed off with that. Then one day as a treat the cellar was unlocked and a large wooden box was dragged out. The bagpipes! The lid was opened and… OMG! the bag had rotted away completely, the pipes looked pathetic and very disappointing, and the whole thing stank of nameless dead creatures… I can’t hear the sound of the pipes to this day without finding it (a) stirring yet (b) enough after a short time and (c ) a reminder of a broken dream… The end.

‘TAKEN TO THE CLEANERS': REEF FISH & CLEANING STATIONS

A cleaning station is a place where fish and and other aquatic life congregate to be cleaned. This involves the removal of parasites both externally and internally, and is be performed by various creatures including, on the coral reefs of the Bahamas, cleaner shrimps and various species of cleaning fish such as wrasses and gobies. The process conveniently benefits both the cleaned and the cleaner.

When a fish approaches a cleaning station it will open its mouth wide or position its body in such a way as to signal that it needs cleaning. The cleaner fish will then remove and eat the parasites from the skin, even swimming into the mouth and gills of the fish being cleaned.

AMAZING WHALE, DOLPHIN & MANATEE PHOTOS FROM ABACO


Whale Fluke (BMMRO Abaco Bahamas)AMAZING WHALE, DOLPHIN & MANATEE PHOTOS FROM ABACO

The BMMRO (Bahamas Marine Mammal Research Organisation) had a great June for sightings of cetaceans and sirenians. Here is a sample of their wonderful photos from recent research expeditions (with thanks as ever for use permission).

RANDY THE WEST INDIAN MANATEE

After the recent excitement of Abaco’s manatee GEORGIE having returned to Cherokee after another of her epic journeys, another West Indian manatee has arrived at Sandy Point (conveniently the location of the BMMRO HQ). Sirenians and cetaceans are generally recognised from particular patterns to flukes or fins. The second image shows the notch in Randy’s tail that confirms ID.

“TOOTHY CRITTERS”: BARRACUDA ON ABACO

We’ve had some sharks swimming around the blog, for example HERE. But not a great deal about barracudas. Time to put that right. Melinda Riger’s excellent photographs tell you the basics of what you need to know – they are lean, mean biting machines with wicked teeth. In fact, ‘cuda bites are quite rare (unless you you very stupid or very unlucky) and many of the common sense rules that apply to fraternising with sharks in their own element apply equally with ‘cudas.

Lobbing a brightly-coloured lure from a skiff using a spinning rod into the general vicinity of a barracuda can result in a heart-stopping few seconds as the fish plunges towards the lure at astonishing speed. If it takes it, there’s even more fun to be had bringing it in. ‘Cuda steaks are delicious, but some care needs to be taken. These fish are known carriers of CIGUATERA fish-poisoning. Click the link to find out about the unpleasantness of the toxin involved. On Abaco, ‘cudas from one side of the island are OK, and from the other side may be suspect… just make sure you know which is which before you cook your supper…

DOLPHINS OF ABACO: WONDERFUL PHOTOS FROM THE BMMRO

The BMMRO (Bahamas Marine Research Organisation) is based at Sandy Point, Abaco. It is dedicated to researching, monitoring, and protecting the marine mammals of a very large area. Not just cetaceans – the dolphins and whales. Recently, a small number of West Indian manatees (sirenians) have been making the northern Bahamas their home. I’ve written plenty about Georgie the adventurous manatee in the past – and in April she returned to her favourite place, Cherokee, after a bit of time away from Abaco.

Recently, photographer Shane Gross spent some time with the BMMRO and took stunning photos of dolphins. It’s impossible to say, or think, anything unpleasant about these lovely, intelligent, playful creatures. Say you ‘don’t much care for dolphins’, and you’d be more than halfway to having a down on kittens. Here are some magnificent images that deserve a wide audience.

ABACO’S ASTOUNDING UNDERGROUND CAVES (2)


ABACO’S ASTOUNDING UNDERGROUND CAVES (2)

This is the second of a series of photos taken by diver Hitoshi Miho in the underground cave systems of Abaco in conjunction with the  Bahamas Caves Research Foundation. This series forms part of a wider project for the blog in due course. With Hitoshi’s kind permission, here are a few more examples of his wonderful images of the silent and mysterious world that lies beneath Abaco. I’ve recently been lightly involved with marine pollution and the environmental effects of ill-considered development. One dreads to imagine the adverse effects on these caves and the blues holes that might result from a massive dredging project of the sort currently being contentiously and litigiously carried out in the pristine waters of Bimini. Thousands of years of crystal development could be lost in a comparative blink of an eye.

PUFFER FISH: BAHAMAS REEF FISH (19)

PUFFER FISH: BAHAMAS REEF FISH (19)

10 PUFFER FISH FACTS TO ASTONISH YOUR FAMILY & FRIENDS

1. Puffers can inflate their bodies in an instant by ingesting huge amounts of water and becoming water-filled balloons.

2. They need a startling form of defence like this (or ‘piscatorial superpower’) because they can’t swim very well.

3. However, a persistent predator will find that they contain a toxin (tetrodotoxin TTX) that is a hundred times stronger than cyanide. One puffer fish has enough toxin to kill quite a few humans.  Agatha Christie was unaware of this – had she been, we might have had a classic  multiple murder mystery based on the contents of a fish tank… “Poirot and a Fishy Tale of the Caribbean”

4. Selected parts of a puffer fish are a delicacy in some cultures (‘fugu’, in Japan). Trained chefs are used to avoid mass deaths among diners.

5. Sharks are the only species immune to the puffer fish and are not much bothered by a small fish that can blow itself up.

6. Puffers have skin, not scales; most have toxic spines of some sort. Bright coloured ones are probably more toxic than their duller cousins.

7. It’s worth knowing what an uninflated puffer looks like before you try to pet a passing fish and have a toxic encounter.

8. There are more than a hundred puffer species in the world, found where there are warm shallow waters.

9. No all puffers are toxic; and some are more toxic than others.

10. I have no idea of the relative toxicity of the 2 puffer species featured here. Sorry about that. Take care!

CHECKERED PUFFER FISH

I photographed some Checkered Puffers at Sandy Point, Abaco last summer. None was puffed up, and I wasn’t about to upset them. The following photos of a small group of puffers were taken from above and not underwater (“no fear”).

I don’t know what species of puffer the one below may be, but I do know I don’t want it in the palm of my hand. I include it from an ‘info for kids’ site to illustrate what the full balloon looks like. I’m wondering if all one needs to deal with them is a pin on the end of a long stick…

A BONEFISHING CHALLENGE ON ABACO: THE ‘WHICH?’ REPORT


_MG_4668_1280x853_

A BONEFISHING CHALLENGE ON ABACO

In January I posted an article called BONEFISHING ON ABACO: A CHALLENGE IS ACCEPTED. This stemmed from contact online with fisherman and fly tyer Mark Minshull, who kindly tied some flies for me to try on the Marls. In the post I showed pictures of my manky flybox and his immaculate flies. We agreed to see how things turned out while I was on Abaco in March, and  that I would report back…   

image24

Mark 1 Specimen Bonefish Flies

THE ‘WHICH?’ REPORT ON MARK 1 BONEFISHING FLIES

We set out to test the efficacy of  prototype ‘Mark 1′ bonefishing flies in the waters of the Abaco Marls. Our testers came from the US (TC & AH), Northern Ireland (AB), and England (RH). All are proficient fly fishermen with experience of several prime bonefishing destinations between them, except for the Englishman RH who was included to add balance to the trials by adding the element of incompetence. His fly box remained an object of ridicule throughout the tests, until he resorted to using a more carefully chosen small fly box containing his most successful flies, some ‘Delphi Club Approved’ flies and the test flies. 

QUALITY All our testers agreed that the Mark 1 flies were beautifully designed and tied. As flies, their quality was rated ‘superb'; ‘bloody good'; and ‘very impressive’. As potential winners for the waters of Abaco, however, there was considerable doubt about the suitability of the pattern for colouring, shape and size.

THE TEST AREA We used the huge area of prime bonefishing territory of the mangrove swamps and sand banks on the west side of Abaco known as the Marls. Our testers were familiar with the waters and all had fished them numerous times. The sea depth, depending on tide, is a few feet at most. The consistency of the bottom is of lightweight, pale coloured mud.

Bonefishing, Abaco Marls Abaco  1

It is usually easier to look out for the shadows of the fish on the light bottom than for the fish themselves, which are often difficult to see in the water. Half-close your eyes and look at this image – the fish almost disappears, but the shadow is clearly visible. It is hard to believe the wonderful colouring of the fish until it is out of the water.Bonefish, Abaco Marls Abaco 2

THE TESTS The initial reservations of the testers unfortunately proved justified in the field. The testers all found that the fish tended not to follow the flies at all, and mostly behaved as if they had not seen them, even with the most accurate casts. The few ‘follows’ observed produced refusals of the fly at the end. Disappointingly, no fly was taken by a single fish throughout the trials.

OBSERVATIONS Our testers had some useful comments. Above all, the Mark 1 flies were undoubtedly of excellent quality and design. They simply were not suited to the waters – or the bonefish – of Abaco. TC thought they might work in Belize. It was thought that larger versions might attract permit. Overall, the Mark 1s were so radically different from the tried and tested fly patterns used successfully on Abaco that the 3 competent fishermen soon forsook the experiment and caught fish using more familiar flies. The 4th tester, lacking any finesse, might have fluked a take against the odds , but even he drew a blank.

THE PROFESSIONALS The Guides in each case had been fishing the Marls since they could walk and hold a rod. They each examined the flies, shook their heads and kept their thoughts to themselves. We interpret this as indicating a tendency for the local guides to doubt the effectiveness of the Mark 1 flies.

IMG_1169

RH’s ‘Selected Specimen’ Fly Box

RESULTS ANALYSIS  The flies above show (front row) the 3 versions of the Mark 1 fly; (middle row) the highly effective Delphi Daddy and Delphi Diva patterns, with one random silver concoction of unknown origin; (back row) ; 2 browny / pale patterns plus a shocking pink one that the guides wisely forbade and, below, 3 roughly matching flies that brought great success even for RH this year (including 12 boated and 5 lost in one day), sourced from renowned tackle specialist E. Bay.

CONCLUSION The flies that catch the bones on Abaco tend to be pale and to have ‘streamer’ tails and / or a fair amount of sparkle. A touch of pink seems to be good. Too much pink, not so. Rubbery legs can be very effective (except in the fisherman after lunch). But lovely lifelike dark shrimp imitations are of no interest to the fish of the Marls.

THE CONCH QUEST OF ABACO…


Conch ©Melinda Riger @G B Scuba

THE CONCH QUEST OF ABACO…

Conchs are gastropods. They are food. They are decoration (anyway, the shells are). For some, they are a living. And on Abaco they are everywhere – alive in the waters, and as shells scattered on  beaches or piled up outside restaurants. So the quest for conch is an easy one. There are fears of overfishing, however, and an active organisation The Bahamas National Conchservation Campaign exists to protect them. Another similar Bahamas organisation is Community Conch.conchs-at-sandy-point-1 We found a nice half-buried conch shell at Sandy Point. It was full of sand grains and tiny shells – mini gastropods and bivalves – that took some time to wash out of the spiralling internal structure. Here are some studies of the shell. IMG_2438IMG_2442IMG_2444IMG_2445IMG_2448IMG_5279IMG_5278 The damage to the shell above is the place where it has been bashed in to enable removal of the occupant. In order to do so, it is necessary to break the strong vacuum that would prevent extraction if you tried by the conventional route. Effectively the conch anchors itself to its shell and must be cut out. The best way to make the hole is with the spiral tip of another conch. This breaks the suction and enables you to prise out the occupant…

RAYS OF SUNSHINE ON THE ABACO MARLS


Stingrays Abaco Marls 1

RAYS OF SUNSHINE ON THE ABACO MARLS

The Marls of Abaco are prime bonefishing grounds, a vast area of labyrinthine mangrove swamps, sandy islets, channels and shallow flats on the west side of the main island. The fish are wily and powerful, the fly hooks are barbless, and each one caught, retained, boated and swiftly released is a prize. There’s plenty of other wildlife to be seen. Heron and egrets, ospreys, belted kingfishers, wading birds and many other bird species make the Marls their home. In the water, there are snappers, jacks, barracuda, and sharks of various kinds and sizes. These latter range from small black tip, lemon and hammerhead sharks to more substantial contenders, with the occasional massive bull shark to add a frisson for those on a suddenly fragile-seeming skiff… 

There are also rays. I have posted before about the SOUTHERN STINGRAY and the YELLOW STINGRAY Out on the Marls I have mainly seen Southerns as they move serenely and unhurriedly through the warm shallow water. A couple of weeks ago, we were out with the rods when we had a completely new Ray experience. I’m not overly given to anthropomorphism and getting too emotional about encounters, but we all found this one quite moving – even our very experienced guide.

Then they slowly drifted away across the sand…Stingrays Abaco Marls 7

According to our guide, this gently protective behaviour is not uncommon. They may well have been completely unrelated, the large ray tolerating the smaller one accompanying it through the waters and offering a kindly wing in the presence of danger or suspicious objects like us.

Stranding Response to Support Conservation of Marine Mammals in the Bahamas 

Increasing capacity and available funds to respond rapidly to strandings in The Bahamas will increase our ability to determine cause of death and/or successful rehabilitation of marine mammals. At the first stranding workshop held in the Bahamas in 2008, the Honourable Lawrence Cartwright, Minister of Agriculture and Marine Resources officially opened the workshop stating “I believe the establishment of a Marine Mammal Stranding Network in The Bahamas will serve to promote the conservation of marine mammal species and their habitat by improving the rescue and humane care of stranded marine mammals, advancing stranding science, and increasing public awareness through education.” This funding will provide the resources to train veterinarians on how to work with stranded marine mammals as well as provide the resources to respond to strandings.

Field Research & Outreach to Support Conservation of Bahamas Marine Mammals

Cetaceans are long-lived, highly specialised animals with delayed reproduction and low fecundity, which makes them incapable of rapid adaptation and thus particularly vulnerable to anthropogenic impacts. BMMRO has compiled an unprecedented long-term dataset for the region, which has become increasingly valuable to inform about the baseline ecology of some odontocete species. This research will ensure that this important work continues to fill key gaps in our knowledge about the ecology of marine mammals. Additionally, we will increase awareness and build capacity amongst Bahamians, both of which will contribute to local conservation needs.

JANUARY SIGHTINGS

For Abaco, the excitement is the sperm whale seen just off the Rocky Point area. More generally for the northern Bahamas, in addition to the manatee Georgie (former temporary resident of Abaco) and others, there was a manatee reported on Eleuthera. It looks as though these gently creatures continue to find the area to their liking.

SPOTTED & SMOOTH TRUNKFISH: BAHAMAS REEF FISH (16)

THE SPOTTED TRUNKFISH is a reef fish distinctive for its dark spots on a silvery-white background. It’s very wrong of me to comment, I know, but arguably its appearance is amusing. It probably feels the same about divers with all their gear…Trunkfish ©Melinda Riger @GBS copyTrunkfish © Melinda Riger @ Grand Bahama Scuba copy 2

However the trunkfish deserves to be treated with due respect. When touched, they secrete a colourless toxin from glands on their skin. The toxin is only dangerous when ingested, so divers are unlikely to be harmed by the it.  Predators however are at risk, and creatures as large as nurse sharks are known to have died as a result of eating a trunkfish.

THE SMOOTH TRUNKFISH is almost a negative of the spotted trunkfish, with white spots on a dark background rather than vice versa. Adults develop hexagonal patterning on their sides. They also secrete toxins and are best left untouched. Their ability to pucker up is impressive…Trunkfish (Wiki)Trunkfish © Melinda Riger @ Grand Bahama ScubaLactophrys triqueter (Smooth Trunkfish) juvenile Wiki

JUVENILE FRENCH ANGELFISH – BLACK WITH YELLOW BANDSFrench Angelfish (juv)

The French angelfish Pomacanthus paru is found in the western Atlantic  and in parts of the eastern Atlantic. They are mainly seen around shallow reefs, often in pairs. They feed on sponges, algae, soft corals and small invertebrates.

Juveniles are extremely useful members of the reef fish community, providing cleaning stations. They service many species including jacks, snappers, morays, grunts, surgeonfishes, and wrasses, removing parasites.French Angelfish ©Melinda Riger @ GBS

Angelfish are monogamous, and defend their territory robustly.  They swim around the reef during the day but at night they shelter in so-called ‘hiding spots’, which they return to each evening.wikiFrench Angelfish 2 ©Melinda Riger @ GBS

MARINE DEBRIS? NO THANKS! 10 FACTS FROM NOAA


Ten Things You Should Know About Marine Debris

monksealMonkseal being rescued from marine debris

Entangled-harbor-seal NOAA Marine Debris
Our waterways are littered with stuff that doesn’t belong in them. Plastic bags, cigarette butts, fishing nets, sunken vessels, glass bottles, abandoned crab traps…the list is endless. Some of this marine debris comes from human activity at sea, and some of it makes its way into our waterways from land.
While we know that marine debris is bad for the environment, harms wildlife, and threatens human health and navigation, there is much we don’t know. How much marine debris is in our environment? How long does it last? How harmful is it to natural resources or human health and safety? How long does it take to break down in the water? The NOAA Marine Debris Program is finding answers to these questions.

1. It doesn’t stay put

While a lot of debris sinks, much also floats. Once this marine debris enters the ocean, it moves via oceanic currents and atmospheric winds. Factors that affect currents and winds (for example, El Niño and seasonal changes) also affect the movement of marine debris in the ocean. Debris is often carried far from its origin, which makes it difficult to determine exactly where an item came from.

2. It comes in many forms

Marine debris comes in many forms, ranging from small plastic cigarette butts to 4,000-pound derelict fishing nets. Plastic bags, glass, metal, Styrofoam, tires, derelict fishing gear, and abandoned vessels are all examples of debris that often ends up in our waterways.img_0510_ss-1

3. It’s your problem, too

Marine debris is a problem for all of us. It affects everything from the environment to the economy; from fishing and navigation to human health and safety; from the tiniest coral polyps to giant blue whales.

4. NOAA is fighting this problem

The NOAA Marine Debris Program works in the U.S. and around the world to research, reduce, and prevent debris in our oceans and coastal waterways. Much of this work is done in partnership with other agencies, non-governmental organizations, academia, industry, and private businesses.The Marine Debris Research, Prevention, and Reduction Act, signed into law in 2006, formally created the Marine Debris Program. The Act directs NOAA to map, identify, measure impacts of, remove, and prevent marine debris.

5. Some debris is being turned into energy

Abandoned and lost fishing gear is a big problem. It entangles and kills marine life and is a hazard to navigation. Based on a model program in Hawaii, the Fishing for Energy program was formed in 2008 to tackle this problem with creative new ideas. The program is a partnership between NOAA, Covanta Energy Corporation, National Fish and Wildlife Foundation, and Schnitzer Steel.This program offers the fishing community a no-cost way to dispose of old or derelict fishing gear. Once removed from the environment, the gear is transported to the nearest Covanta Energy-from-Waste facility. About one ton of derelict nets creates enough electricity to power one home for 25 days!

6. Marine debris can hurt or kill animals

Marine debris may be mistaken by some animals for food or eaten accidently. Often, larger items like nets, fishing line, and abandoned crab pots snare or trap animals. Entanglement can lead to injury, illness, suffocation, starvation, and even death. NOAA is working with many partners to tackle this problem by reducing and preventing marine debris in our oceans and waterways.

7. There’s a lot to learn about this problem

We know that marine debris is a big problem, but there’s much we need to learn. NOAA funds projects across the country and works with scientists and experts around the globe to better understand how marine debris moves, where it comes from, and how it affects the environment. This knowledge will help us find better ways to tackle the problem.

8. You can help us get the word out!

The NOAA Marine Debris Program offers a heap of creative products to get the word out about marine debris. Looking for brochures, posters, fact sheets, or guidebooks? We’ve got those. Like videos? We’ve got those, too. We even have a blog! You’ll find it all online.

9. This is a global problem.

Marine debris is a global problem that requires global solutions. NOAA experts work with scientists and organizations around the world to share lessons learned, discover what programs work best, and map out future strategies to fight this problem.

10. Small steps lead to big results

Fighting the marine debris problem begins at home.

  • - Try to cut back on the amount of trash you produce.
  • - Opt for reusable items instead of single-use products.
  • - Recycle as much of your trash as you can.
  • - Join local efforts to pick up trash.
  • - Keep streets, sidewalks, parking lots, and storm drains free of trash—they can empty into our oceans and waterways.

WTF? (WHAT’S THAT FISH?) REMORAS: WEIRD SUCKERS

WTF? (WHAT’S THAT FISH?) REMORAS: WEIRD SUCKERS

WHAT ON EARTH ARE REMORAS?

Remoras (Echeneidae), also known as Sharksuckers, Whalesuckers or Suckerfishes, are  ray-finned fish that grow up to 3 feet long. Remora ©Melinda Riger @ G B Scuba copy

You may have noticed them in pictures of sharks and wondered briefly why they hang out with such dangerous creatures. There is filmed evidence that remoras do occasionally get eaten by their hosts…383586_510314062323321_1002533913_n

WHAT DO THEY DO?

Remoras have remarkable dorsal fins that form a sucker-like organ with a ribbed structure. It looks a bit like the sole of a trainer or beach shoe.Remora (head( ©Melinda Riger @ G B ScubaThis bizarre organ can open and close to create or release suction, enabling it can latch onto larger marine creatures. The remora can increase suction by sliding backward, or it can release itself by swimming forward – the ‘slats’ are smooth in one direction, and rough the other way. They have been known to attach themselves to boats. And scuba divers. Even with hairy legs…

WHAT KIND OF CREATURES DO THEY GET ATTACHED TO?

Remoras  associate with specific host species. They commonly attach themselves to sharks, manta rays, whales, turtles, and manatees / dugongs. Smaller remoras may latch onto fish such as tuna and swordfish, and some travel in the mouths or gills of large manta rays, ocean sunfish, swordfish, and sailfish.File:Manta-ray australia.jpgFile:Sea turtle and remora.JPGFile:Mother and baby sperm whale.jpg

WHY WOULD THEY WANT TO DO THAT?

The relationship between a remora and its host is known as  Commensalismspecifically ‘Phoresy‘. The host to which it attaches for transport gains nothing from the relationship, but also loses little. The remora benefits by using the host as transport and protection, and also feeds on morsels dropped by the host. Controversy surrounds whether a remora’s diet is primarily leftover fragments, or the feces of the host. Maybe it’s a healthy  mix of both.

WHERE CAN I FIND ONE?

Remoras are found in tropical, sub-tropical and temperate waters, including the mediterranean. You will definitely find them in the Bahamas. Melinda’s photos were all taken in the waters south of Grand Bahama.

ARE THEY USEFUL TO MANKIND IN ANY WAY?

Yes, but not in a good way, some may think. Some cultures use remoras to catch turtles. A cord or rope is fastened to the remora’s tail, and when a turtle is sighted, the fish is released from the boat; it usually heads directly for the turtle and fastens itself to the turtle’s shell, and then both remora and turtle are hauled in. Smaller turtles can be pulled completely into the boat by this method, while larger ones are hauled within harpooning range. This practice has been reported throughout the Indian Ocean, especially from eastern Africa near Zanzibar and Mozambique,  from northern Australia, Japan and even the Americas.

Because of the shape of the jaws, appearance of the sucker, and coloration of the remora, it sometimes appears to be swimming upside down (see above). This probably led to an older name reversus, although this might also derive from the fact that the remora frequently attaches itself to the tops of manta rays or other fish, so that the remora is upside down while attached.

THANKS FOR THAT. BUT WHERE CAN I GET MORE INFO ON THESE SUCKERS?

RIGHT HERE – AN EXCELLENT VIDEO WITH PLENTY OF LIVE REMORA ACTION

OH! FINAL QUESTION. ARE REMORAS EDIBLE?

I though someone might ask that, so I’ve checked it out. Here is the best recipe I have found, expanded slightly from a blokey Australian chat thread:

Recipe for cooking Remora

  • put a 12 ltr pot on to boil
  • when the pot is bubbling violently, add 2 whole remora, 2 garden rocks, 1 carrot & a large turnip
  • add grandfather’s boots to taste, and turn heat down after 3 hours
  • simmer for a further 6 hours
  • turn off heat and drain carefully
  • remove and discard remora, and serve the rest on a bed of tin tacks
