Wikipedia Abstract

The thorny skate (Amblyraja radiata) is a species of fish in Rajidae family. It mainly lives near the bottom of the coastline of North Atlantic Ocean in depths ranging from 20 to 1000 metres and temperatures from 1 to 10 degrees Celsius. It was also located in Lake Melville, near Goose Bay, Labrador. Rivers empty into the lake and the lake bottom is mostly made up of sand. Thorny skates have been caught in this lake in the 1980s by ice fishermen when outside temperatures were -30 degrees C.
