The angelshark, Squatina squatina, is an angel shark of the family Squatinidae found in the northeast Atlantic from southern Norway, Sweden and the Shetland Islands to Morocco and west Sahara, including the Canary Islands and the Mediterranean between latitudes 65° N and 15° N, at depths down to 150 m. Its length is up to 1.83 m.
The angelshark is found on the continental shelves from close inshore to at least 150 m depth. It lies, with only its eyes protruding, buried in sand or mud. The nasal barbels have expanded, slightly spatulate, unfringed tips. The anterior nasal flaps are weakly fringed, and the head is broadly concave between the eyes. There are short stout thorns in symmetrical groups on the snout and between the eyes, and a pair between the spiracles. There is a median dorsal row of spines.
It feeds mainly on bony fishes, but also skates, crustaceans and molluscs.
Coloration is a uniform dark tan above, pale below. The dorsal surface has small irregular dark spots, with a regular pattern of several small to largish blackish spots, and no ocelli.
Reproduction is ovoviviparous, with 9 to 20 pups per litter.
