Description
Max. size: possible 354 cm, most adults smaller.

Color: A strongly marked color pattern, changing with growth. Young below 60 cm have the back dark brown or blackish, with vertical yellow bars, spots and reticulations, and the underside of the head, abdomen and tail whitish, but in subadults and adults the dark areas break up into scattered dark spots on a yellowish background, shading into the whitish ventral surface.

A large shark. Head with 5 small slits, the last 3 behind pectoral fin origin and the last 2 very close to each other; no gillrakers; nostrils close to front of snout, with short barhels and nasoral grooves connecting them with the mouth but without circumnasial grooves; no nictitating lower eyelids; snout very short, broad and bluntly rounded; mouth short, nearly transverse, and far forward on head, well in front of eyes; teeth small, poorly differentiated in different regions of the mouth, with moderately long medial cusps and short cusplets on sides. Two dorsal fins, the base of the first extending forward of pelvic fin origins as a low keel that reaches level of pectoral fin bases but with insertion posterior to pelvic fin origins; second dorsal fin half the size of first or less; anal fin present, rounded but not keel-shaped, with its origin under rear third of second dorsal fin base; caudal fin nearly or quite half of total length, strongly asymmetrical, with a deep subterminal notch but with the lower lobe hardly developed. Caudal peduncle not strongly depressed, without lateral keels or precaudal pits, but with dermal ridges extending forward onto sides. Intestinal valve of ring type.

Dioecious, internal (oviduct) fertilization, nonguarders, open water/substratum egg scatterers. Oviparous. Egg cases are large, dark brown or purplish black, with longitudinal striations. Size at birth 20-26 cm TL.
