Short description

Dorsal spines (total): 2; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

Probably feeds on bottom invertebrates and small fishes (Ref. 6871). Oviparous (Ref. 247).
