Description

The numbray is a small electric ray from the Indo-West Pacific. The species grows to about 18 cm and has a round, flat, pear-shaped body disc and a short tail. The pectoral fins house powerful electric organs with which it can deliver a shock to stun prey and defend itself; that shock can give a person a painful surprise. As a bottom-dweller it often lies half-buried in sand or mud and hunts worms and small crustaceans. The IUCN assesses the species as Least Concern (LC).
