This sharpnose ray has several characteristics, including relatively short snout and disc, small eyes, 107-114 pectoral radials, and 85-94 vertebral centra in total. It can reach the maximum size of 29 cm disc width, while the birth size is around 7-9 cm disc width.

This demersal species is found living at the depths of up to 40 m in the coastal regions of Indonesia (Sumatra, Java, Borneo, and Bali), Malaysia (Malay Peninsula, Sabah, and Sarawak), Singapore, Brunei Darussalam, and Thailand.

Indonesian sharpnose rays are often caught by local or national fisheries as fresh or salted seafood delicacies for local communities. Its species name "biasa", meaning "ordinary" in Malay and Indonesian, might suggest that this ray is commonly consumed and found in local fish markets.
