The Arctic skate (Amblyraja hyperborea) is a species of fish in the family Rajidae. It lives near the seabed between 140 and 2,500 m deep in the Arctic Ocean and waters around Canada and northern and north-western Europe, in the northern Pacific Ocean, and in waters surrounding Antarctica and New Zealand.[2]
The Arctic skate is about 1 m long and is gray-brown with large dark spots. Its underside is white with dark patterns. It has thorns in line from back to near the end of its tail. It is oviparous; its eggs are capsules with hard horns on each corner. It eats all sorts of small animals at the bottom of the sea.[2]
