This species is distinguished by the following characters: a long caudal fin (49.9-54.2% TL), five dorsolateral ridges along the body, visible even in hatchlings; spiracles bean-shaped, large (length 0.4-1.7% TL); eyes small (length 0.9-2.1% TL); barbels two and short (0.6-2.8% TL); gill slits five, with fourth and fifth partly fused so only four noticeable from a distance; pectoral fins large (anterior margin length 10.4-19.1% TL), are broad and rounded; first dorsal fin originates far posteriorly above the pelvic fins; pectoral-fin rays of semi-plesodic structure, reaching ca. 66-88% of pectoral fin; vertebrae; total 207-262, monospondylous precaudal 43-49, diplospondylous precaudal 38-50, diplospondylous caudal 120-175, precaudal vertebrae 81-101; tooth rows on upper jaw 13-30, on lower jaw 22-30, and series count, upper jaw: 7-27, lower 8-16; ring-type intestine with 18-20 valvular turns. Two color morphs, with a three-stage ontogenetic color and pattern change: the Zebra morph with juveniles with dark brown background and cream colored bands (zebra-like), transitionals light brown with dark bands, broken up by dots and adults beige to yellow with spotted pattern (can be leopard-like); the sandy color morph: transitionals light beige background with swirly pattern of narrow, darker brown bands with tiny spots breaking up the pattern and with adults uniformly sandy beige with tiny dark brown freckles (Ref. 125658).

A tropical inshore shark found on sand, rubble, or coral bottoms of the continental and insular shelves (Ref. 247). Recorded to have entered freshwater (Ref. 4735). Rather sluggish at least during the day (Ref. 247). Probably nocturnal, feeds mainly on mollusks, but also small bony fishes (Ref. 9993). Also known to eat crustaceans (crabs and shrimps) and sea snakes (Ref. 43278). Oviparous (Ref. 43278, 50449). Slow-swimming and able to squirm into narrow cracks, crevices and channel in reefs while searching for food (Ref. 247). Readily kept in captivity (Ref. 247). May bite when provoked (Ref. 247). Utilized fresh and dried-salted for human consumption and also for fishmeal; livers processed for vitamins; fins dried for the oriental sharkfin trade; offal utilized for fishmeal (Ref. 247). Possibly reaching 354 cm TL (Ref. 9993, 47613). Caught in drift net intended for sharks (Ref. 47736). Reported from freshwater in the Philippines but needs to be confirmed (Ref. 43278).
