Head with 5 large gill slits, all in front of pectoral fin bases, their upper ends extending onto dorsal surface of head; no gillrakers; spiracles usually present but very small; no nasal barbels or nasoral grooves; eyes very large, without nictitating eyelids; snout conical (not greatly elongated or flattened and blade-like); mouth very long and angular, extending well behind eyes; no true labial furrows; anterior teeth very large, with long, narrow, hooked, sharp-edged but unserrated cusps and no cusplets, set in 2 rows on either side of symphysis in both jaws, and not separated in front by small symphyseal teeth; upper anterior separated from the smaller laterals by a gap and tiny intermediate teeth. Two low dorsal fins, the first about midway between the pectorals and the pelvics, and well in front of pelvic fin bases, the second somewhat smaller than the first, but larger than anal fin; caudal fin short, strongly asymmetrical, with a pronounced subterminal notch and a short ventral lobe. Caudal peduncle slightly depressed, with a low keel on each side and upper as well as lower precaudal pits. Intestinal valve of ring type, with close-set turns resembling a stack of washers.

Dioecious, internal (oviduct) fertilization, internal live bearers. Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed. With 4 young in a litter, born at 40-43 cm.
