Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 6-8; Anal spines: 3; Anal soft rays: 6 - 8. Diagnosis: Lateral line scales (43)45-49(51); above lateral line (9.5)10-11(10.5); right pharyngeal teeth 5-6 (Ref. 55426). Differs from its congeners by having eye diameter greater than snout length, usually 43-47 + 2-3 scales on lateral line and 3½-5 scale rows between lateral line and pelvic origin (Ref. 59043).

Found in coastal rivers and terminal segments of main rivers (Ref. 26100). Occurs in middle and lower reaches of streams, with slow current and underwater vegetation. Forms large spawning aggregations (Ref. 59043). Threatened due to habitat destruction (Ref. 26100).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Forms large spawning aggregations. A female spawns with one or a few males, which press the female against the substratum and eggs are released. These movements attract other individuals to start spawning. The aggregations disperse after about 20-60 seconds and many form again several times. Deposits adhesive eggs (Ref. 59043).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00309 - 0.01230), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.0 ±0.2 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 to moderate vulnerability (25 of 100) .
