Outfitted with glossy, swishing tails and fan-like fins, snailfish now come in delightful shades of pink, purple, and blue.
Scientists learned three recent species of snailfish about 5 miles below the ocean's surface.
"These fish are part of the Liparidae family and do not conform to the preconceived stereotypical image of what a deep-sea fish should look like", university officials said in a statement. Instead of menacing jaws and a hefty frame, the three types of fish found are small, translucent and have no scales to speak of.
"My interest is mainly the fish, so I am biased in thinking the new snailfish are unbelievable", study author Thomas Linley of Britain's Newcastle University told Newsweek. "Beyond the reach of other fish they're free of opponents and predators", he explained in an on-line assertion.More news: Nintendo Switch Getting Classic NES Controllers
Appearing active and "very well-fed", these snailfish are probably at the top of the local food chain-predator to other invertebrate prey.
The team captured footage of the new fish species and even managed to capture one fish by setting a trap.
Along with these new snail fish, the crew also filmed rare footage of Munnopsids, which are small crustaceans with extremely long legs.
In the conditions present about 4.7 miles (7.5 kilometers) below the ocean surface, a squishy body is helpful in withstanding cold and extreme pressures, Linley said.
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.More news: Check out the official iPhone XS, XS Max and XR promo videos
"Their gelatinous structure indicates that they are perfectly adapted to live under extreme pressure and, in fact, the hardest structures in their bodies are the bones in their inner ear - which give them balance - and their teeth".
Newcastle scientists and engineers worked for five years developing technology for the exploration of ultra-deep environments, like the Atacama Trench, which runs almost 3,700 miles along the west coast of South America. "Without the extreme pressure and cold to support their bodies they are extremely fragile and melt rapidly when brought to the surface", Linely added. This specimen followed prey into one of the traps researchers set. These creatures belong to an unidentified species of the Munnopsidae family and grow to be the size of an adult human hand.
As well as swimming backwards, using paddles on their bellies to propel themselves, the snailfish can shuffle along the seafloor like spiders.
The research will be discussed at the 2018 Challenger Conference which kicks off at the university this week.More news: Hugo Lloris will learn 'life lesson' from drink driving charge - Mauricio Pochettino
