Description

Bleeker's butterfly ray is a large ray from the Indo-West Pacific. The species grows to about 106 cm across and has a very wide, rhomboid, wing-like body disc and a short, banded tail with a venomous spine. As a bottom-dweller it often lies half-buried in sand and mud bottoms of shallow coastal water and searches for crustaceans, molluscs and small fish. The venomous spine can inflict a painful wound. Owing to fishing the IUCN assesses it as Vulnerable (VU).
