Biển Sống nổi và đáy; Mức độ sâu 0 - 200 m (Ref. 3688), usually 15 - 50 m (Ref. 54220). Subtropical; 56°N - 12°N, 23°W - 42°E (Ref. 54220)
Eastern Atlantic: British Isles to Cape Blanc, Mauritania; (exceptionally further south) Senegal and around the Canary Islands and Madeira. Common south of 40°N (Spain, North Africa) in the Mediterranean (Ref. 4781).

Các tia vây lưng cứng (tổng cộng): 11; Các vây lưng mềm (tổng cộng): 11-12; Tia cứng vây hậu môn 3; Tia mềm vây hậu môn: 7 - 9. Body oval and compressed. Canine teeth, with 4 to 6 anterior teeth very developed in each jaw.
Inhabit hard bottoms (rock or rubble) down to 200 m depth. Usually found in shallow water less than 50 m deep (Ref. 9987). Adults solitary; young gregarious (Ref. 12482). Young fish caught with traps. Feed on fish, mollusks and cephalopods. Important food fish. Marketed fresh or frozen (Ref. 9987). Some attempts to culture this species have been successful. Due to low market supply, the potential for selling these fish from aquaculture operations seems to be good (Ref. 9987). A spear-fisherman cites a specimen caught in Greece (Corfu) with an overnight bottom-line about 1.60 m and 42 kg (Ref. 48271), but the identification cannot be verified.
Gonochoric, but some specimens are hermaphroditic. Species of separated sexes (although some individuals may be hermaphrodite in young stages). In the Mediterranean, reproduction takes place between March and May, in areas near the coast. Embryo development lasts about 3 days at 17°C.
