Short description

A pale sand-colored ray, often with ellipses of dark spots on dorsal side of rounded disk (Ref. 26938). Grayish to reddish brown, many rounded blotches outlined with blackish spots. Dark bands across tail up to dorsal fin. Snout darkened (Ref. 7251).

Inhabits coastal waters, on sand or mud bottoms (Ref. 26340). Common along sandy shorelines, sometimes near coral reefs (Ref. 12951). Buries itself with only eyes protruding (Ref. 12951). Nocturnal, moves to shallow bays at night to feed; prefers worms, but may take juvenile snake eels, anemones, and, small crustaceans (Ref. 12951). Produces broods of 4 to 15 young (Ref. 26938). Can discharge between 14 and 37 volts. Contact with the skin can produce a severe electric shock. In addition to the main electric organ, this species possesses a bilateral accessory electric organ (Ref. 10011) speculated to have a possible role in social communication (Ref. 10489). Reported to taste good, but not fished commercially. Traded as an aquarium fish at Ceará, Brazil (Ref. 49392).
