Description

The smallthorn sand skate is a skate of the family Arhynchobatidae from the south-eastern Pacific and south-western Atlantic around southern South America. The species grows to about 50 cm and has a flat, rhomboidal pectoral disc with numerous small thorns and a short snout. It lives on sand and mud bottoms of the continental shelf. As a bottom hunter it feeds on small crustaceans, worms and molluscs. Reproduction is oviparous, with a distinct pairing in which the partners embrace. Unlike stingrays a skate lacks a venomous tail spine; it is harmless to humans.
