Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10 - 11; Dorsal soft rays (total): 11; Anal spines: 1; Anal soft rays: 9; Vertebrae: 26. This miniature species is distinguished by the following reductive character states: laterosensory canal system of head and body is reduced; scale rows in longitudinal series 20-23, oblique; with low number of caudal-fin rays (14 segmented, middle 10 branched, 4 procurrent); A I, 9; dorsal-fin elements total 20-21; upper lip darkly pigmented and presence of a black stripe on basal third to fourth of dorsal fin (Ref. 114925).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
