Description

The white skate is a large skate of the family Rajidae reaching a total length of about 2.3 metres and a wingspan of over one and a half metres. The diamond-shaped body, formed by the pectoral fins fused to the head, has a pointed snout; the upper side is grey-brown with fine pale spots, while the white underside has a dark-rimmed rear edge to the fins. Young animals are more boldly marked than adults. The species lives on sand and gravel bottoms of the continental shelf and upper slope of the north-eastern Atlantic and the Mediterranean. On the bottom it hunts fish, crustaceans and squid. It grows slowly and has declined sharply through fishing; it is assessed as Endangered (EN).
