Strange fish live at a depth of 1,500 meters washed up on the Alaska coast

The fish, nearly two meters long, landed on the coast of Alaska, USA, has a strange shape and is very rare.

According to Earth Touch News, strange fish came near a pier in the city of Gustavus, Alaska, USA, 1.8 meters long. At first, a local unloading worker, who discovered the fish, mistakenly thought it was a flounder.

The fish has the scientific name of ragfish (Icosteus aenigmaticus) , which belongs to the class of rays. Adults swim along the northern Pacific Ocean at a depth of 1,200m to hunt squid, small fish, octopus and jellyfish. They are the food source of sperm whales, the largest toothed predator in the world.

"This fish undergoes a strange transformation when aging: the pelvic fins disappear and the longitudinal spine shrinks. The smaller ones live more than 730m above the water surface while the adults live at a depth of nearly 1,500 m ", the research team at Glacier Bay National Animal Conservation Park in Gustavus said.

The body of another fish of the same species once washed into Glacier Bay area last year. Test results show that both fish's stomachs are empty. They are children and are carrying eggs.

It is very rare for ragfish to land ashore. According to a perennial naturalist at Gustavus, these are the cases that caught the only ragfish recorded in the last 40 years.
