Краткое описание определительные ключи | морфология | морфометрия

членистые (мягкие) лучи анального плавника: 204 - 221. Distinguished from other congeners by having the following combination of characters: the rictus falling short of the vertical through the posterior border of the posterior naris; depth of the caudal filament 6.7-9.1% CL; length of the caudal filament 14.4- 27.0% LEA; anteroposterior length of premaxilla equal to the transverse width; length of the posterior ceratohyal approximately the same length as the ventral hypohyal; length of the coronomeckelian bone less than 20% the length of Meckel’s cartilage; head length to the rear of the opercle 15.0-16.3% LEA; mouth width 7.0-10.3% HL; teeth on the dentary restricted to the anterior one-half or slightly more of the dorsal margin; presence of a narrow dark stripe along the lateral line and a broad band of dusky to dark pigmentation overlying the basal pterygiophores of the anal fin; 19-21 pectoral-fin rays; and 204-221 anal-fin rays (Ref. 93148).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00172 - 0.00768), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
