Short description Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 18 - 20; Vertebrae: 40 - 41. This species is distinguished from its congeners by the size of the humeral spot (2-3 vs. 4-9 horizontal series of scales), number of scale rows below of the lateral line (3-4 vs. 4-8), and total number of pelvic-fin rays (7 vs. 8); differs from most congeners by the number of branched anal-fin rays (18-21 vs. 21-34, and 17 in H. tridens), except H. beni and H. helleri; differs from H. beni and H. helleri by the number of lateral line scales (40-42 vs. 44-53 and 42-44) (Ref. 85819).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00258 - 0.01408), b=3.16 (2.96 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
