Description

The lined round stingray is a small round ray from the eastern Pacific, from the southern Gulf of California to Ecuador. The species grows to about 46 cm and has a round, flat body disc with a row of thorns along the back and a long tail bearing a venomous spine. As a bottom-dweller it lives in shallow coastal water to about 30 metres depth and feeds on small crustaceans and fish. Owing to its slow reproduction the IUCN assesses it as Near Threatened (NT). The spine can inflict a painful, venomous wound.
