Horizontally oval eyes, small spiracles, two moderate-sized spineless dorsal fins and an anal fin, the first dorsal base well ahead of pelvic bases. Precaudal pits present. Caudal fin with a strong ventral lobe and lateral undulations on its dorsal margin. They feed on small bony fish, small elasmobranchs, cephalopods, crustaceans, and echinoderms.
