Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 12; членистые (мягкие) лучи спинного плавника (общее число) : 12 - 14; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 12 - 14; позвонки: 26. This species is distinguished by the following set of characters: D XII,12-14 (usually XII,13); A II,12-14 (usually II,13); pectoral-fin rays 16-18 (usually 17); spiniform caudal-fin rays 2; tubed lateral-line scales 14-17 (usually 15-16); total gill rakers on first branchial arch 27-32; body depth 1.8-2.0 (mean 1.9) in SL. Colouration: in life overall yellowish brown, typically with lateral greyish to purplish stripes along scale rows; the dorsal and anal fins are brownish with dark-brown triangular marking posteriorly and caudal fin yellowish; pectoral fin with a prominent round, blackish spot covering the entire base and axil (Ref. 122787).

Estimates based on models

Preferred temperature (Ref. 115969): 24.6 - 28.8, mean 27.4 (based on 376 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00940 - 0.04644), b=2.98 (2.80 - 3.16), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
