General data
The starry smooth-hound (Mustelus asterias) is a houndshark of the family Triakidae. It is found on the continental shelves of the northeast Atlantic, between latitudes 61° N and 16° N, from the surface to a depth of 200 m (660 ft). It can grow up to a length of 1.4 m (4 ft 7 in).
The starry smooth-hound grows to a length of about 140 cm (55 in). It is grey or greyish-brown with a scattering of small white spots on its dorsal (upper) surface and white on its ventral (under) surface. It is a long, lean fish with a somewhat rounded snout and rows of shallowly projecting teeth. The two dorsal fins are of similar shape, but the hindmost one is a little smaller than the foremost. A notch occurs in the upper lobe of the caudal fin and the lower lobe is of medium size.
This species of houndshark is found in the eastern Atlantic Ocean and the Mediterranean Sea. Its range extends from southern Norway, Scotland, and the North Sea southwards to Algeria, Morocco, and Western Sahara. It is found in the whole of the Mediterranean, but not in the Black Sea. It is found on the continental shelf and around islands at depths to at least 200 m (660 ft) and prefers places where the seabed is sand or gravel.
