Description

The round skate is a small deep-sea ray of the family Rajidae reaching about 60 cm. The disc, formed by the pectoral fins fused to the head, is almost round to heart-shaped, distinguishing the species from most diamond-shaped skates; rows of thorns run down the back and tail. The body is brownish with light and dark spots. The species lives on mud and sand bottoms of the continental shelf and slope on both sides of the northern Atlantic, usually between about 150 and two thousand metres. On the bottom it hunts small crustaceans and worms. It lays eggs in horny capsules and grows slowly; because of its deep-sea life it is rarely observed.
