Description

The apron ray is an electric ray (Narcinidae) from the coastal waters around southern South America. The species has a round, flattened, disc-shaped body and a short tail. Like other electric rays it bears an electric organ in the pectoral disc with which it can deliver a shock to stun prey and defend itself. It lives bottom-bound on the continental shelf and feeds on worms and crustaceans. It is ovoviviparous. When touched it can deliver an electric shock.
