Morfologie | Morfometrie
Distinguished by the following characteristics: D1 VI, D2 I/I 1 - 12, A 1/11, P 17 - 18, C 16 - 17 principle rays (adult specimen with 13 branched rays; branching of fin rays not completed in the juvenile specimen); all rays of the first dorsal fin are elongated in the adult specimen (tips pronounced in the juvenile), with D1 III longest. ctenoid scales; LL 37, including scales on caudal fin (squamation not completely developed in juvenile specimen), TR 8; head, nape, predorsal area, breast, ventral side of abdomen (midline) and base of P naked; area anterior of a line from the dorsal origin of the pectoral fin to the origin of the second dorsal fin naked; anterior most scales in lateral midline reach the base of the pectoral fin in the adult specimen (only near to it in the juvenile); some of these most anterior scales are cycloid (Ref. 86376)
Occurs inshore in the Mediterranean but found in deeper waters off Portugal (Ref. 4696).
