More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; oceanodromous (Ref. 51243); depth range 30 - 500 m (Ref. 3198). Subtropical; 42°N - 22°S, 26°W - 36°E
Eastern Atlantic: off Portugal and Strait of Gibraltar to Namibia, including Cape Verde and the Canary Islands. Also from the Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm 10.8, range 14 - ? cm
Max length : 65.0 cm TL male/unsexed; (Ref. 3397); common length : 30.0 cm TL male/unsexed; (Ref. 2683)
Inhabit rocky or sandy bottoms; individuals descending to greater depths with growth. The stocks migrate seasonally between the coast and deeper waters in accordance with local hydrographic conditions and their life cycle. Feed mainly on fish and crustaceans; the young on plankton (Ref. 3688). Gonochorists (Ref. 4781).
