Pacific Fish Discovery

The Deepest Ocean

One third of the entire Earth’s surface is made up of the Pacific Ocean. It is a vast body f water which is teaming with aquatic life. One of the most interesting discoveries to take place in this ocean involved the study of deep sea life.

In the Western side of the Pacific lies the Mariana Trench. It is the deepest known region of the ocean. It is estimated to be as deep as 36,000 feet. It is hard for life to flourish in these depths. It is dark, cold and unforgiving. It takes very specific evolutionary traits for an animal to survive.

Life Found

For this reason, it was of great interest to the scientific community when, in November 2017 it was announced that a new type of fish had been discovered there.

It was discovered at a depth where no other living fish had been found until then. It is called Pseudoliparis swirei, or more commonly the Mariana snailfish.

Characteristics of this new life form

The Mariana snailfish is unusual in appearance. It has no scales. Instead, it is covered in smooth skin that is both white in color and translucent. When photographed the skeletal structure of the fish is clearly visible.

The fish has no predators and is at the top of its food chain. Despite modern technologies allowing scientists to study these fish even closer than ever before, very little is yet known about them. One thing is for certain: They are a sign that life can exist at even the most extreme of environments.

The Discovery

Starting in 2014, scientists lay numerous traps baited with mackerel. It was in these traps that researchers first discovered the snail fish. After three years at least 37 specimens had been found. During these years its predatory lifestyle was also revealed.
