Telatrygon biasa

Last updated

Telatrygon biasa, the Indonesian sharpnose ray, is a whiptail stingray found in the Indo-Malay Archipelago.[1] The Indonesian and Malay term "biasa", which translates to "ordinary", was chosen for this ray's species name because it is a frequent sight in local fish markets.[2][3] According to measurements, the largest disc width recorded for this ray is 29 cm, and newborn individuals have a disc width ranging from 7 to 9 cm.[4]

Biology and range

The ray has a relatively short snout and disc, small eyes, 107-114 pectoral radials, and 85-94 vertebral centra.[4] The species is retained for human consumption.[1] This bottom-dwelling ray lives in shallow coastal waters at depths not exceeding about 40 meters.[1][4] The ray's known range includes Indonesia (specifically Sumatra, Java, Borneo, and Bali), Malaysia (the Malay Peninsula, Sabah, and Sarawak), Singapore, Brunei Darussalam, and Thailand.[4]

A decline in the ray's population is ongoing because it is caught by small-scale local fisheries.[1] Local communities often consume Indonesian sharpnose rays as fresh or salted seafood, with these rays frequently appearing in markets.[3]

What the specialist sources record
