Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 4; Raggi dorsali molli (totale) : 27 - 28; Spine anali: 2; Raggi anali molli: 17 - 18. Lunate caudal fin with elongated lobes in adults; yellowish green on head and dorsally on body, shading to light yellow ventrally; greenish yellow dorsal and anal fins, broad black stripe near dorsal fin base; caudal fin base and lobes greenish yellow with centroposterior part transparent with pale greenish yellow rays. Segmented caudal rays 11-12 (usually 11); lateral line terminating below 3rd to 7th dorsal soft rays (Ref. 54980).
Body shape (shape guide): elongated.
Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
