Three new fish species found in the depths of the Pacific

a exploration in one of the deepest places in the Earth has recorded imagery unusual of what is supposed to be three new species of the elusive & # 39; snailfish & # 39; (slimy fish).

With the participation of 40 scientists from 17 nations otherwise, including the doctor Alan Jamieson and the doctor Thomas Linley, from the University of Newcastle, United Kingdom, the expedition to the fossa from Atacama has a lot of information about the life in one of the most places deep in the world.

Below the new discoveries they are what the team thinks they are three new species from slimy fish. Temporary & # 39; the snake fish Atacama pink, blue and purple & # 39;, the video shows the fish that feed and Interaction in your secret world 7 500 meters under the surface.

this one fish they are part of the family & # 39;Liparidaeand they do not fit in the image stereotypically preceded by what a fish of waters shallow. Instead of gigantic teeth and a structure threatening, the fish that they wander the most shallow of the ocean they are small, translucent, is missing flakes and very capable of living where few other organisms can do it.

the snail will be presented as part of theChallenger conference 2018& # 39; that begins in the University of Newcastle from today and it will last until Friday. "There is something with the & # 39;snailfish ExplanationThis allows them to adapt to life very much deep. Beyond the reach of others fish they are free from competitors and predators"says the doctor Thomas Linley, of the University of Newcastle, United Kingdom. "As the video clearly shows, there are many dams invertebrates and the & # 39;snailfish Explanation& # 39; are the most important predatorsThey seem pretty active and they look very good, "he adds.

"Your gelatinous structure means that they are perfectly adapted to live under extreme pressure and, in fact, the most difficult structures in their bodies are the bones in his inner ear who gives them balance and their teeth. Without extreme pressure and cold to hold their bodies, they are extreme fragile and the to melt fast when they reach the surface, "he says.

Surprisingly, the equipment managed to catch one of the new species fish similar to snails that followed them dam from amphipod in one of the traps. the specimen only one was in a very good condition and, after careful preservation, is described by the team Newcastle with the help of colleagues from United States and the Natural history museum of London.

the Atacama well, a ditch from almost 6.000 kilometers long and more than 8,000 meters deep, it stretches along the west coast of South America. The scientists and engineers of the University of Newcastle are pioneers in the use of technology to explore these environments ultra-deep during the last five years and until now they have almost completed 250 implementations of his new systems fromlanding& # 39 ;, they explain.

By using two landers who are capable of the depth of the ocean (11,000 meters) equipped with camera & # 39; s HD and traps, the team Newcastle evaluated the animals that are in the ditch. Designed and developed in University of Newcastle, the landing module is thrown overboard and goes freely to the bottom of the ocean, where he performs one variety of tasks check and sampling.

It can bear four o'clock so that a fall to the bottom sinks and after waiting for 12 to 24 hours Furthermore, the researchers they send an acoustic signal to the trap, which releases weights and the landing module comes to the surface with the aid of the flotation. This allows the team to capture fish specimens and make video images of life at the bottom ocean.

In this last expedition to Atacama Trench in the SE Pacific off the coast of Peru and Chile, the team has deployed its camera system 27 times 2 537 meters to the deepest point, Richard & # 39; s Deep, a little more than 8,000 meters. More than 100 hours of video were recorded and 11,468 photographs were made at the bottom of the sea.

In addition to this type fish, the team also filmed some images surprising rare isopods from long legs, known as & # 39;Munnopsids& # 39 ;, that are as big as a grown-up hand. These shellfish have small bodies, extraordinarily long legs and swim backwards and downwards, and float themselves with paddles on their ventral side – their & # 39;belly& # 39; – for straightening on the seabed and implement them long legs to walk like one spin.

"We do not know which species"Munnopsid& # 39; These are these, but it is great to get them into action in their own natural habitatespecially the change that they go through when they go from swimming to hiking, "he concludes. Linley.
