Short description

Dorsal spines (total): 2; Anal spines: 0. The Zebra bullhead shark, Heterodontus zebra, has a large blunt head, low supra-orbital crest gradually sloping behind eyes, dorsal fin spines, anal fin, and zebra-pattern of dark, narrow vertical bands on a pale background (Ref. 9838; 6871). As characteristic of members of the family, caudal fin with a moderately long dorsal lobe and moderately long ventral lobe, the latter shorter than the dorsal lobe, vertebral axis raised into caudal-fin lobe (Ref.9838).

A common but little-known shark found on the continental and insular shelves in depths down to at least 50 m (Ref. 247, 11230) in the South China Sea, but deeper and in 150 - 200 meters off Western Australia (Ref. 43278). Probably feeds on bottom invertebrates and small fishes (Ref. 6871). Oviparous (Ref. 247).
