The crested bullhead shark is a moderately common benthic and epibenthic shark, occurring from close inshore to about 90 m depth. It feeds primarily on sea urchins, but also on crustaceans, molluscs, and small fishes. Reproduction is oviparous, the egg cases being spirally flanged and with long tendrils. The young are about 22 cm in length when they hatch.
The body has broad blackish bands or saddle markings and has a crested bull head.
