Description

The starry smooth-hound is a slender shark of the family Triakidae reaching about 1.5 metres. The grey back is scattered with numerous small white stars, from which the species takes its name, and the belly is white. Unlike many sharks it has no sharp cutting teeth but flat, mosaic-like molars, with which it mainly crushes crabs and other crustaceans, supplemented with molluscs and small fish. The species lives on sand and gravel bottoms of the north-eastern Atlantic, the North Sea and the Mediterranean and moves in schools to shallower coastal waters in summer. It is viviparous and bears live young. The starry smooth-hound is harmless and a popular sport fish; due to fishing pressure it is assessed as Near Threatened (NT).
