The initially time biologist Heather Mason Jones heard about the seahorses on Eleuthera Island, she experienced difficulty believing in a position where by seahorses had been as popular as other fish. Following 29 yrs finding out the animals, the University of Tampa seahorse specialist experienced hardly ever found much more than a handful with each other underwater in her whole vocation. But after she was immersed in the emerald waters of the mile-lengthy Sweetings Pond, which sits on a slender crescent of an island in the Bahamas, she begun to feel the hoopla.

“It was an totally magical moment,” she states, introducing that she saw sixteen of the animals in numerous dives throughout the initially weekend in the drinking water there — an tremendous volume, specified she experienced only at any time found a few or four in a one dive or snorkel excursion. “Until you see it, it’s challenging to feel that folks are not exaggerating.”

Although they may perhaps be nicely known in common imagination, seahorses are really an uncommon sight in the ocean, even for scientists whose task is to observe them. Even further study by Mason Jones and her colleagues has considering that discovered that Sweetings Pond has one particular of the most concentrated populations of seahorses in the earth — at times, above 10 times denser than the world-wide normal.

The pond has been somewhat guarded from fishing, which may perhaps be one particular of the reasons seahorses are so abundant. Xiong Zhang, a seahorse researcher at the University of British Columbia not associated in Mason Jones’ study, states bottom trawling in individual is one particular of the important threats to seahorses worldwide, due to the fact the nets can capture seahorses and wipe out the substrate attributes they want to clasp onto.

The concentration of seahorses in Sweetings Pond represents a special prospect for scientists to improved understand the fish in general. “We have the great managed process,” states Jessica Elson, who labored with Mason Jones on seahorse study while she was a University of Tampa biology undergraduate. “We have a special prospect due to the fact there are so many of them.”

But the clock may perhaps be ticking on this seahorse paradise. A couple yrs back, a common tourism website stated that the region was a terrific position to snorkel with seahorses, sparking fears among the scientists that incoming readers could wipe out parts of the bony fish’s habitats. Mason Jones and her colleagues started functioning with associates in the Bahamas Countrywide Trust to safeguard the pond. She hopes the safety of the park brings sustainable tourism that will educate folks about seahorses and add to strengthening their conservation worldwide.


The pond is 45 toes deep in some spots, and is landlocked. Some locals even feel a sea monster lives there, earning the pond the nickname “the Loch Ness of the Bahamas.” Monster aside, the special and sheltered ecosystem has the exact salinity as the close by ocean, but is devoid of many of the important predators that prey on seahorses.

Mason Jones and Elson’s study also discovered that the lined seahorses at Sweetings Pond vary from their cousins in oceans all around the island, with smaller sized bodies and in different ways formed heads. Although these dissimilarities are not plenty of to warrant calling them a independent species, Mason Jones states the isolated nature of the population indicates these seahorses are slowly and gradually drifting absent, in a genetic perception.

Part of the explanation seahorses are so rare exterior of Sweetings Pond has to do with their ecology and patterns. For starters, the fish want something stable on the substrate to clutch onto with their tails, as they are not especially superior swimmers (correct). Sweetings Pond supplies them with plenty to cling to: vegetation, coral and bivalves, including Atlantic pearl oysters.

Ongoing study by Mason Jones, Elson and their colleagues has discovered that the seahorses of Sweetings Pond behave a good deal in different ways at night time. Through the working day, they dangle out upside-down at the pond’s bottom, so scientists experienced assumed this was what they often did. But it turns out that at night time, they shift to the tops of vegetation and remain upright.

The scientists are not however absolutely sure why they take on these postures, or whether or not one particular is a sleeping place. What is much more, the staff found that the seahorses had been much a lot easier to find immediately after dark due to their upright posture, and they had been congregated in much denser groups — up to a few times as dense in some circumstances.

Their new research, the initially to study seahorse habits at night time, demonstrates that seahorses may perhaps be much more popular in some places than biologists previously believed — scientists just are not looking at the correct times, Elson states.
