Biology     Glossary (e.g. epibenthic)

A very common inshore to offshore shark of the continental shelf occurring at depths of a few meters to slightly over 100 m (Ref. 244). A specialist feeder that prefers cephalopods, also feeds on small bony fishes (Ref. 244). Viviparous (Ref. 50449). Utilized fresh and dried salted for human consumption, and processed into fishmeal (Ref. 244).
