HIP! HIP! HIPPOCAMPUS: LET’S CELEBRATE SEAHORSES

Melinda Riger, doyenne of the deep and photographer to the stars (brittle stars, basket stars, starfish etc), undertook her 5000th dive a few days ago. She swims with sharks almost daily, and points her lens at the varied reef life she encounters along the way. Her gold prize for the dive turned out to be one of the smallest creatures she encountered: the seahorse. Hippocampus (Ancient Greek: Ἵππος, horse and Κάμπος, sea monster) is a unique fish, deriving from the pipefish, with more than 50 species known worldwide. I can feel a Rolling Harbour fact list coming on…

10 SEAHORSE FACTS TO DAZZLE YOUR FRIENDS WITH

  • Only seahorses and razorfish swim upright / vertically all the time
  • Their tails are prehensile and enable them to moor on coral, seagrass etc
  • They have no scales, but skin stretched over bony plates arranged in rings
  • The ‘coronet’ on a seahorse’s head is unique to the individual
  • Seahorses are pathetic swimmers: the slowest have a top speed of 5′ per hour
  • They feed by ambush, rotating the head and sucking prey in with their snout
  • A seahorse’s eyes can move independently of each other, like a chameleon 
  • The Bahamas is home to H. erectus and the dwarf seahorse H. zosterae
  • Despite rumours, they don’t mate for life. Some may stay together for a season
  • The smallest seahorse in the world – the pygmy – is a maximum of 15mm long

MAKING BABY SEAHORSES: A MOST UNUSUAL ARRANGEMENT

There’s no getting round it: seahorse courtship and reproduction is highly unusual. Here is a summary of how it goes (there’s a lot more to it, but life is short):

  1. COURTING This may last for many days. They may change colour; they swim together; they entwine tails; they attach themselves to the same strand of coral or seagrass and turn slowly round it in unison (a so-called ‘pre-dawn’ dance). The final courtship dance may last several hours while the male & female prepare for the next stage.
  2. EGG TRANSFER When the time is right the female transfers her eggs – hundreds of them – via her ovipositor  to the male, in the process of which they are fertilised. Handily, he has inflated a special egg pouch located on his abdomen. She then buggers off.
  3. GESTATION The fertilised eggs grow inside the egg pouch of the male and develop into baby seahorses. This process may take from 10 days to a few weeks. During this time, the female will visit for a short ‘morning greeting’ and some intertwining action.
  4. ‘BIRTH’ In due course the male ejects the baby seahorses from his pouch using muscular contractions. These may number from five to (get this!) 2,500 at a time; on average 100–1000. Job done. Then the tiny seahorse babies are on on their own…

THREATS TO SEAHORSES

The attrition rate of baby seahorses through predation is high (as for most fish species), but the prolific breeding rate reduces the effect on the overall populations.  As so often, there are human-related threats, not least habitat destruction, overfishing and pollution. There’s a less expected problem: the importance of seahorses in Chinese medicine.  Their presumed healing qualities are used to treat impotence, wheezing, enuresis, pain and to assist labour. For these purposes, some 20 million seahorses a year are caught and sold. Increasingly they are reduced to pill or capsule form. 

Seahorse values depend on the species, but weight for weight dried seahorses retail for *unbelieving face* more than the price of silver and almost that of gold in Asia, from US$600 to $3000 per kilogram. Ours not to reason why.

USELESS SEAHORSE FACTS

  • Seahorse is an anagram of seashore
  • The Seahorses were an English rock band, formed in 1996 by guitarist John  Squire following his departure from The Stone Roses. They split in 1999
  • Devendra Banhart’s song ‘Seahorse’ contains these inspiring lyrics:
    I wanna be a little seahorse
    I wanna be a little seahorse
    A little seahorse
    I wanna be a little seahorse
    I wanna be a little seahorse
    I wanna be a little seahorse
    I wanna be a little seahorse
  • I’m losing the will to live. Let’s meet Otis.

MANGROVE DIE-BACK IN THE ABACO MARLS: THE FACTS


Mangroves, The Marls, Abaco, Bahamas (Keith Salvesen, Rolling Harbour)

MANGROVE DIE-BACK IN THE ABACO MARLS: THE FACTS

For some time now, there has been understandable concern about the increasing evidence of mangrove die-back in the Abaco Marls and elsewhere in Abaco waters. Scientific investigations are ongoing and you will find some of the survey results so far on the excellent Abaco Scientist interactive map HERE. You’ll find other relevant and authoritative mangrove material if you check out the BLOG menu of the website.
Abaco - The Marls

The ‘200 sq. miles’ in my map is debatable, depending what one includes. Other estimates are of 300 or even 400 sq. miles. Whichever, the Marls cover a massive area of mangroves, islets, flats, channels and wonderfully diverse wildlife. A large proportion of the many species – fish, birds, turtles etc – depend on the complex ecology of the mangroves for food, shelter and breeding. Depletion of the mangroves from whatever cause will have a direct effect on the creatures of the Marls.

Stingrays Abaco Marls 6

Ryann Rossi, a PhD student with North Carolina State University, has been researching the worrying phenomenon of mangrove die-back in the Marls this summer. She has written an interesting and informative  account (conveniently in the RH ‘Facts about…’ style) that was published in Abaco Scientist last week. The blue links will take you to the ABSCI site for further information on each topic. I’m grateful to Ryann and ABSCI for permission to use the material.

Five Things to Know About the Mangrove Die-back in The Marls (at this point, anyway)

1. This die-back appears to be the result of multiple stressors acting together. Think of it in the sense of our own body – when our immune system is down, we are often more susceptible to getting sick. The same thing is likely happening to the mangroves.Mangrove Die-back 1 (Abaco Scientist : Ryann Rossi)

2. It appears as though a fungal disease may be taking advantage of already stressed mangroves and causing die-back. We did preliminary surveys across Abaco and found fungal lesions nearly everywhere. However, the fungus was present in different densities in different areas. In the die-back area nearly all the leaves remaining on trees have lesions. We think that this pathogen capitalized on the mangroves being weakened by other stressors such as hurricanes, which cause extensive leaf drop, change in the movement of water, change in sedimentation and erosion.

3. We are still working on identifying the pathogen associated with the lesions we’ve found. We are confident that it is a fungus and are currently growing fungal cultures in the lab to examine defining morphological characteristics in addition to using DNA sequencing to identify the culprit.

4. We have documented the presence of the Robust Bush Cricket (Tafalisca eleuthera) in the die-back areas as well as other areas with high densities of lesions. These crickets are documented to consume Red and White mangrove leaves. As such, we were concerned about their potential role in die-back. We set out a caging experiment to exclude the crickets from certain dwarf Red mangrove trees to see just how much grazing they may be doing in the die-back area. This experiment is ongoing.

Mangrove Die-back 3 (Abaco Scientist : Ryann Rossi) jpg

5. The take home: there is likely more than one causal agent of the die-back in The Marls. Many factors govern mangrove productivity and functioning: nutrient availability, salinity, sedimentation rate, herbivory, and disease are just a few of the factors that contribute to overall mangrove function making it very difficult to pin point which factors may be driving the die-off. On the bright side, we are confident that we have a lead on the causes and we are working hard in the field and laboratory to fully understand what is going on in The Marls.

Mangrove Die Off on Abaco by Ryann Rossi, NCSU

This summer Stephanie Archer and I continued research efforts focused on determining the cause of the mangrove die-off in The Marls (work funded by the National Science Foundation). Our efforts were predominantly focused on the fungal pathogen we found associated with the die-off site. We created a small citizen science and outreach project to document the presence or absence of the pathogen across Abaco. This project consisted of short surveys and leaf collections. In total, 92 areas were surveyed including locations from Abaco and San Salvador. We also took this outreach project to the annual Bahamas Reef Environment Education Foundation (BREEF) teacher training conference.  There we disseminated survey packets to teachers from islands throughout The Bahamas who will help us collect more data on the presence (or absence) of this pathogen on other Islands.

On Abaco, we constructed an experiment to investigate the role of grazing and the presence of fungal lesions on Red mangroves. We simulated grazing using crafting scissors to cut small sections on 600 leaves in 4 different mangrove creeks. We observed the leaves for 28 days to determine if cutting leaves predisposed leaves to fungal infection. At these sites we also trapped for insects to gain an idea of what kind of grazers may be chewing on the leaves. We also did a series of disease incidence surveys that will be routinely monitored for disease progress over the next 2 years. These surveys will allow us to systematically track the progress of the disease. In addition to our field work, we spent many hours in the laboratory isolating fungi from leaves to grow in culture. These cultures were brought back to North Carolina State University and will be sequenced in order to help us identify the fungal pathogen responsible for making the lesions on the mangrove leaves.

OLIVE-CAPPED WARBLERS ON ABACO


Olive-capped Warbler 3.Abaco Bahamas.6.13.Tom Sheley

OLIVE-CAPPED WARBLERS ON ABACO

Abaco has a recorded 37 warbler species. Of these, most are winter residents and some are rarer migratory transients. Only 5 are permanently resident on Abaco: the Bahama Warbler, Bahama Yellowthroat, Olive-capped Warbler, Pine Warbler and Yellow Warbler. You can read about all 5 HERE 

Olive-capped Warbler, Abaco (Bruce Hallett)Olive-capped Warbler, Abaco (Bruce Hallett)

I realise that I haven’t posted about OCWs in their own right; and that as a species they have been unfairly lumped in (by me) with more general warbler posts. Time to put that right by showing some exclusively OCW photos.

Olive-capped Warbler.Abaco Bahamas.6.13.Tom Sheley

OCWs have an unusually restricted range, despite which they remain IUCN-listed ‘Least Concern’. These pretty birds are native only to the western and eastern ends of Cuba, Grand Bahama, and Abaco. Their natural habitat is pine forests and to a lesser extent in mixed forest and coppice areas.

Olive-capped Warbler 6.Abaco Bahamas.6.13.Tom Sheley

If you are lucky enough to see an OCW on Abaco, it’s worth thinking about the rich and unspoilt habitat that ensures its survival there. These little birds, along with other important bird species, enjoy a safe haven in the vast acres of pine forest.Olive-capped Warbler, Abaco (Bruce Hallett)

‘BAHAMAS SHRIMPING’: BANDED CORAL SHRIMPS

‘BAHAMAS SHRIMPING’: BANDED CORAL SHRIMPS

The Banded Coral Shrimp Stenopus hispidus is also known as the banded cleaner shrimp because it cleans other fish (see TAKEN TO THE CLEANERS); and ‘boxing shrimp’ because its stance and the large pincers on the third set of legs give the creature the appearance of a boxer ready to fight.

Banded Coral Shrimp Stenopus hispidus (Johan Fredriksson) a

These shrimps are widely distributed in tropical and sub-tropical waters around the world where coral reefs are found. Their striking colour scheme makes them instantly recognisable.

 BANDED CORAL SHRIMPS: 10 FACTS TO BANDY ABOUT

  • BCSs are decapods, having 5 matching pairs of legs / claws on each side
  • They can be found as deep as 200 metres in the ocean
  • They are also found in aquaria, but need careful management because…
  • They are generally aggressive to other BCSs & shrimps in the same tank and
  • They need room for their long legs and antennae to move freely around
  • However, rather sweetly, they are monogamous and do not eat their partners
  • Diet-wise they are omnivore carnivore scavengers
  • They are said to be amusing to watch as they rush round a tank after food
  • Not a good shrimp to breed: the larvae get stuck in the filtration or get eaten
  • In the sea, they act as ‘cleaner’ fish to larger fish species (see below)

Banded Coral Shrimp ©Melinda Riger @ G B Scuba Banded Coral Shrimp (+ Moray Tail) ©Melinda Riger @ G B Scuba copy

In its capacity as a cleaner shrimp, the BCS solicits passing fish by slowly waving its long, white antennae. It then uses its three pairs of claws to remove parasites, fungi and damaged tissue from the fish. See the video example below.

ABACO’S BIRDING HOTSPOTS (42 OF THE BAHAMAS TOP 100)


Black-necked Stilt, Abaco (Tom Sheley)

ABACO’S BIRDING HOTSPOTS (42 OF THE BAHAMAS TOP 100)

Right now, I’m doing daily checks on the indispensable EBIRD CARIBBEAN in relation to the ABACO PIPING PLOVER WATCH project (and incidentally if you encounter one or more on a beach near you, details would be very welcome – below is what to look out for!).

Piping Plover, Abaco - Bruce Hallett

It occurred to me to check out the contention that Abaco is Numero Uno birding destination in the Bahamas (though sadly lacking the flamingoes, except for vagrants; and the Bahama oriole, now extirpated and confined to select areas of Andros). Sure enough, Abaco has 42 out of the top 100 birding hotspots. In the map below, gray pointers indicate a few observations, blue means 50+ and green represents 100+. Nowhere has yet achieved the flame-red pointer – the ultimate hotspot accolade…

Abaco Birding Hotspots Map (eBird)

People often ask where best to go for quality birding on Abaco. The answer depends of course on the season and on what they are after – for example shorebirds or warblers; parrots or absence of parrots and so on. The Abaco 42 are listed below. There are a couple points to make about the hotspot list:

  • There is a degree of duplication, eg Gorda Cay / Castaway Cay being shown as separate entries, as is Angelfish Point / Angel Fish Point
  • Also, the data gathered by eBird is entirely dependent on regular uploads of checklists. Inevitably the birders will mostly be regulars, with their own preferred beats or perhaps with an interest limited to the area where they live. Some records show long gaps – sometimes a couple of years – between reports. So the eBird data can only give an overview, not a precise record of actual observations or birding effort and success. 

Bahama Woodstar male 3.1.Abaco Bahamas.2.12.Tom Sheley copy

In very general terms, and assuming a broad birding interest, I would recommend the Treasure Cay area; in and around Marsh Harbour; the stretch east of the Highway that takes in Bahama Palm Shores, the Abaco Neem Farm, Delphi, Crossing Rocks & Gilpin Point; the National Park; and Sandy Point. I’m sure there will be other views, but I am thinking primarily of the visitor who has but a single day to spare from a packed schedule of fishing, swimming, sunbathing, eating and drinking… [nb as a soi-disant photographer I’m not so keen on the dumps and landfill. Yes, the birding can be good. No, I don’t want to feature rubbish in my already rubbish photos…]

The Bahamas has an excellent record for producing colourful stamp issues showcasing the wildlife of the islands – birds, reef fish and of course butterflies. I’ve posted about these several time, and they are more or less collected together on a dedicated stamp page HERE. As for the butterflies, they get a new issue every decade or so. Here are the last four.

BAHAMAS MANATEE MAGIC ON ABACO & BEYOND

BAHAMAS MANATEE MAGIC ON ABACO & BEYOND

Four years ago, there were no manatees in Abaco waters. Then a couple of adventuresome sirenians made the trip over from the Berry Is. and since then, there have been at least one, sometimes two and occasionally three resident on Abaco. And for slow, gentle, animals they certainly move around, too. In the past, I wrote quite often about the manatees, charting their journeys based on satellite tracking and sightings. I reported the tantalising prospect of the young male, Randy, hooking up with young female Georgie in Cherokee Sound, only to turn back when he reached Little Harbour. You can read more about the manatees of Abaco on my manatee page HERE.

     Georgie’s epic trip (Sept 12) continued to Cherokee Sound; and Randy’s ‘pursuit’ (Sept 14)Georgie Manatee's direct route to Abaco       Randy's the Manatee's trip Berry Is. to Abaco copy

The most comprehensive source for Bahamas Manatee information is now to be found by joining the open Facebook group BAHAMA MANATEE CLUB, skilfully curated by Felice Leanne Knowles. There, you can follow the meanderings of your favourite Abaco manatee, watching as he or she moves around the island and cays. In recent months there have been sightings of single or pairs of manatees in several places, including Sandy Point, Little harbour, Marsh Harbour, Schooner Bay and Hope Town Harbour (where two are right now). Here’s an excellent example of how, just like a Beach Boy, an Abaco manatee gets around. In July, Randy moved from Sandy Point to Schooner Bay in 2 days. The big question is, did he travel round the longer top route, as he has in the past; or (more likely in the time taken) via Hole-in-the-Wall?

Felice has just produced a great map that shows the present locations of all the Bahamas manatees currently recorded. She has also supplied photos and information about them. Most have names and are well-known to the research team and the locals where they stay. There is one new calf – Gina’s –  this year. One or two manatees are new on the scene and have yet to be identified or named. 

Manatees Throughout The Bahamas

The map shows the last location of the named manatees. The pink dots label females, the green dots label males, and the yellow dots label unknown manatees. The number of unknown manatees has been approximated to reduce error. The photos are of the individual manatees with dates and specific locations of their most recent sighting. We do not have enough data and photos to confirm the unknowns labeled. Any help from the public would be greatly appreciated. Send sighting reports to http://www.bahamaswhales.org/sightings/index.html NB Felice points out Full body and paddle photos are very important for the identification of manatees. Facial shots do not provide enough information for a manatee to be identified”

Manatee Awareness Poster jpg

You may have noticed that several of the manatees shown carry scars attributable to prop wounds. Almost all carry injuries of some sort. Because manatees are slow, gentle, inquisitive and trusting creatures, they are especially vulnerable in harbour areas for obvious reasons. Elsewhere than the Bahamas, boat-strike is one of the main causes of manatee mortality. The BMMRO recently issued the above advisory notice because of the uncertainty about the rights and wrongs of watering manatees from docks with hoses and feeding them lettuce etc. Overall the message is that, though creatures of wonder, they are better off being admired but left to their own devices. They are adept at finding the fresh water sources they need, and their sea-grass diet is amply provided for. Dependence on humans, however well-meaning, is actually harmful.
