Length at first maturity / Size / Vikt / Age
Maturity: Lm 24.7, range 24 - 49.5 cm
Max length : 60.0 cm TL hane/ej könsbestämd; (Ref. 7097); common length : 25.0 cm FL hane/ej könsbestämd; (Ref. 3397)
Adults are found at depths ranging from 305 to 368 m in the eastern Ionian Sea (Ref. 56504). They can be seen up to depth of 370 m (Ref. 4233). They are confined to neritic zones of island shelves, banks and sea mounts; a schooling species (Ref. 4233). Known to migrate between the coast of Sahara and the offshore seamounts possibly reaching the Cape Verde Islands (Ref. 26139). They feed mainly on crustaceans (Ref. 4233). Eggs are pelagic (Ref. 4233).
