Scientists Are Trying to Save This Seahorse Paradise in the Bahamas

This posting appeared in Discover’s once-a-year condition of science situation as “Seahorse Paradise.” Aid our science journalism by turning out to be a subscriber.

The first time biologist Heather Mason Jones read about the seahorses on Eleuthera Island, she had difficulty believing in a spot where by seahorses had been as typical as other fish. Right after 29 yrs researching the animals, the University of Tampa seahorse skilled had in no way witnessed far more than a handful alongside one another underwater in her complete job. But when she was immersed in the emerald waters of the mile-extended Sweetings Pond, which sits on a slender crescent of an island in the Bahamas, she started to consider the buzz.

“It was an totally magical instant,” she suggests, incorporating that she noticed sixteen of the animals in many dives all through the first weekend in the water there — an massive amount, offered she had only at any time witnessed 3 or four in a solitary dive or snorkel journey. “Until you see it, it’s tricky to consider that people aren’t exaggerating.”

Although they could be well acknowledged in well-liked creativeness, seahorses are in fact an abnormal sight in the ocean, even for researchers whose occupation is to observe them. Additional research by Mason Jones and her colleagues has considering that uncovered that Sweetings Pond has 1 of the most concentrated populations of seahorses in the environment — at moments, about 10 moments denser than the international common.

The pond has been comparatively shielded from fishing, which could be 1 of the good reasons seahorses are so ample. Xiong Zhang, a seahorse researcher at the University of British Columbia not associated in Mason Jones’ research, suggests bottom trawling in unique is 1 of the main threats to seahorses all over the world, since the nets can seize seahorses and damage the substrate characteristics they want to clasp on to.

The concentration of seahorses in Sweetings Pond signifies a exclusive option for researchers to much better realize the fish in normal. “We have the ideal controlled program,” suggests Jessica Elson, who labored with Mason Jones on seahorse research when she was a University of Tampa biology undergraduate. “We have a exclusive option since there are so quite a few of them.”

But the clock could be ticking on this seahorse paradise. A number of yrs back, a well-liked tourism website pointed out that the area was a great spot to snorkel with seahorses, sparking fears among the researchers that incoming site visitors could damage components of the bony fish’s habitats. Mason Jones and her colleagues commenced doing work with associates in the Bahamas Countrywide Have confidence in to safeguard the pond. She hopes the protection of the park provides sustainable tourism that will educate people about seahorses and add to improving their conservation all over the world.

The pond is 45 toes deep in some places, and is landlocked. Some locals even consider a sea monster lives there, earning the pond the nickname “the Loch Ness of the Bahamas.” Monster apart, the exclusive and sheltered ecosystem has the similar salinity as the nearby ocean, but is devoid of quite a few of the main predators that prey on seahorses.

Mason Jones and Elson’s research also uncovered that the lined seahorses at Sweetings Pond differ from their cousins in oceans all around the island, with lesser bodies and otherwise shaped heads. Although these dissimilarities are not adequate to warrant calling them a individual species, Mason Jones suggests the isolated mother nature of the inhabitants suggests these seahorses are slowly and gradually drifting away, in a genetic perception.

Element of the cause seahorses are so rare outdoors of Sweetings Pond has to do with their ecology and practices. For starters, the fish want a thing sound on the substrate to clutch on to with their tails, as they aren’t especially excellent swimmers (right). Sweetings Pond delivers them with tons to cling to: vegetation, coral and bivalves, such as Atlantic pearl oysters.

Ongoing research by Mason Jones, Elson and their colleagues has uncovered that the seahorses of Sweetings Pond behave a good deal otherwise at night time. Through the day, they hang out upside-down at the pond’s bottom, so researchers had assumed this was what they always did. But it turns out that at night time, they go to the tops of vegetation and remain upright.

The researchers aren’t nevertheless confident why they just take on these postures, or whether 1 is a sleeping posture. What’s far more, the group identified that the seahorses had been substantially much easier to find immediately after darkish owing to their upright posture, and they had been congregated in substantially denser groups — up to 3 moments as dense in some situations.

Their new examine, the first to take a look at seahorse habits at night time, displays that seahorses could be far more typical in some locations than biologists previously believed — researchers just aren’t hunting at the right moments, Elson suggests.
