Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i analfenan: 112 - 145. Distinguished from other species of the genus by having the following combination of characters: boldly contrasting color pattern of irregular, dark blotches on the back and sides followed by posteriorly by a long pallid area extending far onto the caudal peduncle; pectoral and anal fins translucent; anal-fin rays 112-154 with mean 133.2; vertebral count to base of last anal-fin ray 52-57 with mean 54.5; a relatively deep body, 21-33% of distance to origin of dorsal filament; body depth below origin of dorsal filament less than or equal to postorbital distance (Ref. 78211).

Reported to feed on benthic invertebrates (Ref. 78211).

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=0.00355 (0.00145 - 0.00871), b=3.06 (2.85 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
