deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik

This species is distinguished from its congeners by the following set of characters: a short gape that terminates posteriorly at, or slightly short of, the vertical through the anterior nares; no scales along the mid-dorsal region of the body as far posteriorly as the origin of the electroreceptive filament; anal-fin rays 200-217 (Ref. 84053).

Inhabits clear water system with the bottom formed by small stones and rocks. Feeds on insects and other aquatic invertebrates (Ref. 84053).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00145 - 0.00867), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
