This characteristic distinguishes prey crushing from simply biting, which is a behaviour exhibited by elasmobranchs. While bonnethead sharks feed almost exclusively on crabs, they have the same tooth structure as the Horn sharks (Heterodontiformes). [8]

From 1988 to 1991, there was a New Zealand shark liver fishery and reported catches of draughtsboard sharks were 74–540 tons per year. After the fishery was discontinued, catches ...
