Description
The Tonkin numbfish is an electric ray (Narcinidae) from coastal waters of the Indo-West Pacific. The species grows to about 30 cm and has a flattened, oval, brownish body with a fairly stout tail bearing two dorsal fins. In its pectoral fins it carries powerful electric organs with which it stuns prey and defends itself. As a bottom-dweller it often lies half-buried on sand and mud bottoms and searches for worms and small invertebrates. On contact it can deliver a powerful electric shock.
