Biology
Ovoviviparous. Sex ratio of embryos is about one to one, however, small mothers may have predominantly female embryos and that for a given mother, embryos tend to be of one sex (Ref. 46979). Maximum number of embryos per female may reach 15. The young are capable of giving off electric charges even before they are released from the womb (Ref. 46978). Inhabits coastal waters, on sand or mud bottoms [20078]. Common along sandy shorelines, sometimes near coral reefs [1658]. Buries itself with only eyes protruding [1658]. Nocturnal, moves to shallow bays at night to feed; prefers worms, but may take juvenile snake eels, anemones, and, small crustaceans [1658].
