Description

The eyespot skate is a skate of the family Arhynchobatidae from the south-western Atlantic off south-eastern South America. The species grows to about 79 cm and has a flat, rhomboidal pectoral disc with a conspicuous, ring-shaped eyespot on each side, to which the name refers. It lives on sand and mud bottoms of the continental shelf. As a bottom hunter it feeds on small crustaceans, worms, molluscs and small fishes. Reproduction is oviparous, with horny egg cases. Unlike stingrays a skate lacks a venomous tail spine. Owing to fishing the species is listed as Endangered (EN) and is harmless to humans.
