Snailfish: New species of ghost-like ocean predator found in Pacific

Snailfish: New species of ghost-like ocean predator found in Pacific

They haven't yet come with a scientific name for the fish, so they simply called them pink, blue and purple Atacama snailfish.

As well as the new fish, the researchers also filmed footage of long-legged isopods known as Munnopsids.

Part of the Liparidae family, the fish are unusual in appearance compared to the typical idea of a deep-sea fish.

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.

An global team consisting of 40 scientists from 17 nations embarked on an expedition to search deep in the ocean with their camera and other necessary equipment. "Without the unheard of tension and frigid to beef up their bodies they're extremely fragile and soften all true now when dropped on the surface", Linely added.

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. Scientists filmed the fish in their natural environment as part of an global expedition to remotely explore the Atacama Trench, off the coast of Peru, and the discovery will be presented at the ongoing Challenger Conference at Newcastle University in the United Kingdom. Whatever the adaptations are, they serve the snailfish well: Even though they each clock in at less than a foot long, according to Linley, at such extreme depths, they're "top predators" and "look very well-fed".

While it could be argued that they are yet to be properly tested so far this season, they can only beat what is put in front of them.

Dr. Thomas Linley, who works at Newcastle University, acknowledged it used to be firm snailfish are among the tip predators within the deep depths of the ocean.

The fish are said to have a gelatinous structure that is perfectly adapted to the extreme pressure at the bottom of the trench.

Provisional data indicate that there are three new species related to the family of the snailfish of the Marianas (or slugs of the Liparidaefamily ), whose first specimens were discovered in the Mariana Trench. The ocean where the fish were found is so deep it can take almost four hours for a trap to sink to the bottom. This specimen followed prey into one of the traps researchers set. In Atabasca chute scientists have received more than 100 hours of video and 11 468 photos. Researchers then release an acoustic signal to release weights allowing the lander to float back up to the surface.

However, the scientists were able to bring one of the new species of snailfish to the surface, after it swam into one of their traps. The snailfish discovery will be featured at the Challenger Conference 2018 at Newcastle University.

"They fall apart at like the molecular level", Linley said.
