Description

The smooth dogfish or dusky smooth-hound (Mustelus canis) is a small, slender shark of the family Triakidae from the western Atlantic. The species has a grey-brown, streamlined body and can reach about 1.5 metres. It lives on continental and insular shelves, from shallow inshore waters and the intertidal to about 200 metres deep, and occasionally enters fresh water briefly. Instead of sharp teeth it has flat tooth plates with which it crushes crustaceans such as crabs and lobsters; it also eats mollusks and small fishes. The species is harmless to humans, is fished commercially and is considered Near Threatened (NT).
