Description

The big skate is the largest skate in North America, of the family Rajidae from the north-eastern Pacific. The species grows to about 2.4 metres and has a flat, rhomboidal pectoral disc with a large, conspicuous eyespot on each side that can deter a predator. It lives on sand and mud bottoms of the continental shelf. As a bottom hunter it feeds on crustaceans, molluscs, worms and small fishes. Reproduction is oviparous; notably a single horny egg case can contain several embryos. Unlike stingrays a skate lacks a venomous tail spine; it is harmless to humans.
