Species of shark

The bighead spurdog is a rare and little-known species of dogfish shark in the family Squalidae. It is found in deep water south of New Caledonia, and over the Norfolk Ridge. Reaching at least 90 cm (35 in) in length, this stocky shark is brown above and light below, with a broad head and two dorsal fins with long spines. It is the only member of its genus with both one- and three-pointed dermal denticles. An infrequent bycatch of longline fisheries, this species is listed under Data Deficient by the International Union for Conservation of Nature (IUCN).
