Short description Morphology | Morphometrics

Vertebrae: 35 - 36. A member of the Astyanax scabripinnis species complex that distinguishes from species outside this complex by having anal fin with 14-18 branched rays and body depth shallow (26.9-29.7% of SL). Differs from other species of the species complex by its shallow body depth (26.9-29.7% SL) and the smaller interorbital width (26.9-30.4% HL) (Ref. 57404).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01360 (-0.16462 - 0.19183), b=3.05 (2.95 - 3.15), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 2.9 ±0.3 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) .

Price category (Ref. 80766): Unknown.
