Short description Morfologia | Morfometria

Spine dorsali (totale): 1; Raggi dorsali molli (totale): 7; Raggi anali molli: 19 - 23. Distinguished from other freshwater ariids occurring in Mesoamerica by the following combination of characters: presence of accessory tooth patches on palate; premaxillary tooth band length 2.4-2.9 in its width; ; snout length 1.4-1.8 in postorbital length; lateral gill rakers on first gill arch 17-20 (mode 19); mesial gill rakers on first two gill arches well developed; accessory palatal patches with numerous pointed-conical teeth; premaxillary maxillary barbel not extending behind gill membrane; and dorsomedian fleshy groove on head absent (Ref. 75770).

Occurs only in freshwater, preferring the main channel of medium to large rivers (Ref. 75770).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
