Description

Barnard's skate is a deep-water skate of the family Rajidae from the south-eastern Atlantic off southern Africa. The species grows to about 75 cm and has a flat, rhomboidal pectoral disc with a row of larger thorns along the back and tail. It lives on the outer continental shelf and upper slope at considerable depth. As a bottom hunter it feeds on small crustaceans, worms and small fishes. Reproduction is oviparous, with horny egg cases. Unlike stingrays a skate lacks a venomous tail spine; it is harmless to humans.
