Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 11; Anal soft rays: 9 - 11; Vertebrae: 43 - 46. This species is distinguished by the following characters: no dark pigment on buccal cavity; pale body, usually with large faint dusky spots in several longitudinal series midlaterally on side; pale adipose fin; transparent caudal fin, though dusky near base of each lobe; supraocular ridges extending nearly to predorsal scales; scales above lateral line 4.5; cheek scales in 2 rows; nearly cylindrical head and body with body tapering little posteriorly in dorsal view; large eye; tiny adipose dorsal fin, its length 4.7-10.6% HL; deep anal fin in males, the posterior tip reaching nearly to posterior edge of hypurals when depressed; short pectoral fin, extending to below middle of dorsal fin base (Ref. 84674).

Estimates based on models

Preferred temperature (Ref. 123201): 14.4 - 20.4, mean 16.5 °C (based on 19 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
