Description

The Brazilian cownose ray is a large ray from the western Atlantic, off the coast of South America. The species grows to about 100 cm across and has a flat, rhomboid body disc, an indented, cow-nose-like snout and a long tail with a venomous spine. It often schools in large numbers through shallow coastal and estuarine water and uses its pectoral fins to search for molluscs and crustaceans, which it crushes with flat jaws. The venomous spine can inflict a painful wound. Owing to fishing the IUCN assesses it as Endangered (EN).
