Brevitrygon heterura, the dwarf whipray, is a type of ray of the family Dasyatidae found in the Indo-Malay Archipelago, from Indonesia to Vietnam.[1][2] It inhabits shallow waters in the depth of 25 - 50 meters.[2] This species is one of the most common small ray captured in Indonesia and considered a local delicacy.[1]
The dwarf whipray can be identified through several characteristics, including oval-shaped disc, broad pointed snout, plain colored dorsal surface, absence of skin folds on the tail, and rounded pectoral-fin apex.[2] Female specimens of this species can reach a maximum size of approximately 24 cm disc width.[2]
Habitat & distribution
This demersal ray is usually found in inshore or brackish waters to the depth of 50 meters.[1] It's endemic distribution range stretches from Indonesia, Singapore, Malaysia, Brunei, Thailand, and Vietnam.[1][2]
The dwarf whipray faces direct threats by trawlers on Malacca Strait and Sunda Strait because it is considered as delicacy, mainly in Indonesia.[1]
