Morphology | Morphometrics
soft rays: 15 - 19;
Vertebrae: 39. This species is distinguished from most congeners, except H. mikrostiktos, H. paez, H. tridens, and H. virolinica, by the number of branched anal-fin rays 15-19 (vs. 20-34); Hemibrycon beni differs from these species by the number of lateral line scales 44-53 (vs. 40-42, 39-42, 39, and 40-44, respectively). H. beni differs from H. virolinica by the number of predorsal scales 17-20 (vs. 10-15). H. beni when compared with H. helleri, overlap somewhat with branched anal-fin ray counts 15-19 (vs. 19-23 for the latter), but can be distinguished from each other by the size of humeral spot 3-4 horizontal series of scales and the total number of vertebrae 38-39 in H. beni (vs. 7-8 in horizontal series of scales and 41-43 vertebrae, respectively for H. helleri) (Ref. 85819).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12 (3.03 - 3.21), based on all LWR estimates for this BS (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 (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
