Description
The graytail skate is a deepwater skate (Arhynchobatidae) from the southwestern Atlantic Ocean and around the southern tip of South America. The species has a flat, rhomboid body disc with broad pectoral fins and a long, grey tail, to which the name refers. It lives on the bottom of the continental shelf and slope at considerable depth. As a bottom predator it feeds on crustaceans, molluscs, worms and small fishes. Skates are oviparous: the eggs are laid in horny egg cases with projections. Owing to fisheries the species is endangered. It is harmless to humans.
