3 New Species of Fish Discovered in Extreme Depths of The Pacific Ocean

The Scoop:
A group of scientists say they have discovered three species of fish lurking 5 miles below the surface of the Pacific Ocean

 

The Story:

More than 80 percent of Earth’s oceans are still unexplored. Researchers like Alan Jamieson and Thomas Linley are working to change that.

Joining an expedition to the Atacama Trench, the Newcastle University scientists helped uncover information about life in one of the deepest places on the planet.

Their search discover what the 40-strong team believe to be three new species of sea snails, temporarily names as “the pink, the blue, and the purple Atacama Snailfish.”

The colorful creatures (members of the Liparidae family) were captured on camera feeding and interacting some 4.6 miles below the surface of the Pacific Ocean.

Their presence, however, may not be the most shocking detail: Analysts were surprised to find that these deep-sea animals do not fit the preconceived stereotype.

Instead of giant teeth and an intimidating frame, the fish are small, translucent, scale-less, and, essentially, highly skilled at living where others can’t.

“There is something about the snailfish that allows them to adapt to living very deep,” postdoctoral research associate Linley said in a statement. “Beyond the reach of other fish they are free of competitors and predators.”

Appearing active and “very well-fed,” these snailfish are probably at the top of the local food chain—predator to other invertebrate prey.

Newcastle scientists and engineers worked endlessly for five years developing technology for the exploration of ultra-deep environments, like the Atacama Trench, which runs nearly 3,700 miles along the west coast of South America.

Analysts managed to capture one of the new species, which, when removed from the extreme pressure and cold of their natural habitat, “are extremely fragile and melt rapidly,” according to Linley.

The specimen was in very good condition and is currently being described by the Newcastle group, with help of colleagues from the US and London’s Natural History Museum.

Researchers also filmed “astonishingly rare” footage of long-legged crustaceans known as Munnopsids—about the size of an adult hand. Though the exact species remains unknown, Linley is excited about this discovery.

“Especially the flip they do as they switch from swimming to walking mode,” he added.
