Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturity: Lm 13.3, range 10 - 26 cm
Max length : 40.0 cm TL macho/indeterminado; (Ref. 1371); common length : 20.0 cm TL macho/indeterminado; (Ref. 4645); idade máx. registrada: 5 anos (Ref. 72488)
Espinhos dorsais (total): 0; Espinhos anais 0. Chin barbel well developed. Body brownish yellow dorsally, becoming paler ventrally; a dark blotch is at the base of the pectoral fin.
Occurs mostly from 15 to 200 m in the Atlantic on muddy or sandy bottoms. Feeds on crustaceans, small fish, and polychaetes (Ref. 1371). Used in the production of fish meal, and in southern Europe as a human food (Ref. 35388).
Oviparous, sexes are separate (Ref. 205).
