Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 5 - 6; Raggi dorsali molli (totale) : 33; Spine anali: 3; Raggi anali molli: 33 - 41; Vertebre: 27. First dorsal fin composed of several short spines preceded by an anteriorly directed spine usually completely embedded under skin. Two detached anal spines anterior to soft anal fin. Lateral line curved and undulated, with more or less 10 branches anteriorly and fairly straight posteriorly (Ref. 27363). A black patch on the opercle is a conspicuous character of this species, thus the name signata (Ref. 3157).
Maximum length assumed to be 1.5 * 40 = 60 cm TL (RF).
