PREHENSILE TALES FROM THE REEF (3): SEAHORSING AROUND

It’s Friday at last. It’s springtime. A spirit of benign goodwill is evident in the vicinity of Rolling Harbour. Seahorses are irresistible. Don’t even try to pretend they don’t make you smile. Hippocampophobia is an affliction that, as yet, has never been diagnosed in a human being – for whom fear of beards, clowns and the number 5 (quintaphobia) are known medical conditions. Immerse yourself with these little creatures – and then have a good weekend.

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.

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.

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.

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.”

SEAHORSES: PREHENSILE TALES FROM THE REEF

It’s a year since I last posted about these amazing little creatures, seahorses. I featured a number of photos by Melinda Riger, a couple of videos, some useful facts about them, and for some reason some useless facts that I came across in researching the post. You can chase it down here: SEAHORSES 1

Adam Rees of SCUBA WORKS is another diver, like Melinda, who combines great underwater experience with wonderful photographic skills. This posts showcases some of Adam’s seahorse photography, and if it doesn’t want to make you explore the reefs, I can’t think what will…

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.
