Description

The smallnose fanskate is a skate of the family Arhynchobatidae from the south-western Atlantic off southern South America. The species grows to about 63 cm and has a flat, rhomboidal pectoral disc with a pointed snout. It lives on sand and mud bottoms of the continental shelf. As a bottom hunter it feeds on crustaceans, worms, molluscs and small fishes. Reproduction is oviparous, with a distinct pairing in which the partners embrace; young sometimes follow large objects. Owing to fishing as bycatch the species is listed as Near Threatened (NT). Unlike stingrays a skate lacks a venomous tail spine; it is harmless to humans.
