Echinorhinus - Bramble sharks

Echinorhinus is the only extant genus in the family Echinorhinidae.

This genus includes two extant species of uncommon, little-known sharks. Both species are relatively large sharks, at 3.1 to 4.0 m (10.2 to 13.1 ft) in body length. They are characterized by a short nose and by rough, thorn-like dermal denticles scattered over its body, some of which may be fused together. They have no anal fin. Two small spineless dorsal fins are positioned far back.
