At night they swim around freely, even pelagically (Ref. 35388). Feed on small invertebrates and fishes; chiefly nocturnal. Oviparous, eggs and larval stages pelagic (Ref. 4675). There are dark markings along the scales; the anterior dorsal fin is black and contains venomous spines. Utilized fresh and frozen; can be pan-fried, broiled, boiled and baked (Ref. 9988).
