Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Μαλακές ραχιαίες ακτίνες (συνολικά) : 13; Σπόνδυλοι: 35. Differs from other species of the genus by the combination of the following characters: long pectoral fins always surpassing pelvic-fin origin; anal fin origin at level of a vertical through fifth or sixth dorsal fin rays; one supraopercular and two humeral spots on flanks; two or three maxillary teeth; 35-38 perforated scales in the lateral series; and 24-27 branched anal fin rays. Distinguishes further from most of its congeners by having deep body (36.9-42.6% SL); large eye (10.2-11.9% SL); maxillary length, 100.0-136.6% interorbital width); and presence of 24-25 gill rakers on first branchial arch (Ref. 55798).
