Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7 - 8; Anal soft rays: 12 - 13; Vertebrae: 33 - 34. This species can be diagnosed from all other species of the Anablepsoides urophthalmus group by having the following characters: longitudinal rows of red dots interrupted and replaced by short rows of golden dots on the flank in males (vs. rows of red dots often cotinuous, when interrupted not replaced by golden dots); margins of unpaired fins dark grey in males (vs. never dark pigment concentrated on fin edge to form distinct colored margins); and a horizontal row of red dots on the sub-basal region of the anal fin in males (never a similar color pattern) (Ref. 94717).

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=0.00661 (0.00311 - 0.01404), b=3.09 (2.91 - 3.27), 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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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