Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 19 - 23; Vertebrae: 41 - 43. This species is distinguished from its congeners, except H. jelskii, by the size of humeral spot over 7-8 horizontal series of scales (vs. 3-6). H. helleri differs from H. jelskii by the number of branched anal-fin rays (19-23 vs. 25-30), and number of scales along anal-fin base scale sheath (6-12 vs. 13-28). It is rather similar to H. inambari, but can be distinguished by the size of humeral spot (over 7-8 vs. 5-6 horizontal series of scales), number of predorsal scales (16-18 vs. 13-16), and by the total number of vertebrae (41-43 vs. 39-40) (Ref. 85819).

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=0.00813 (0.00372 - 0.01775), b=3.09 (2.90 - 3.28), 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. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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