Description
The shortnose spurdog is a small dogfish of the family Squalidae reaching about 70 cm. The slender, grey body has a short, blunt snout, large greenish glossy eyes and a stout spine in front of each of the two dorsal fins; the belly is paler. The species is widespread in temperate and tropical seas, including the eastern Atlantic, on the continental shelf and slope, usually between tens and several hundred metres. In schools it hunts close to the bottom for small fish, squid and crustaceans. Reproduction is ovoviviparous and slow, with small litters of live young. Because of this slow life history, spurdogs are sensitive to fishing pressure.
