The whip-like tail is longer than the body and lacks the skin fold found in some related species.

The dwarf whipray is a uniform pinkish or beige colour and has been mistaken for a horseshoe crab in turbid water.

Its range extends from Thailand, Cambodia and Vietnam to Singapore, Malaysia, the Philippines and Indonesia.

It occurs close to the sandy seabed on the inner continental shelf at depths usually less than 50 m (164 ft).

The gestation period is not known, but before birth, the pups are fed on secretions from the uterine wall, a process known as histotrophy.
