Kurzbeschreibung Morphologie | Morphometrie

This species readily distinguished from all its congeners by possessing a conspicuous ocellated posttemporal spot, which is always greater than half orbital diameter, often equal or larger than orbital diameter (vs. smaller or absent); it differs from C. igara and C. jurubi, by the absence of numerous spots scattered over the back and sides (in both sexes), and by the presence, in males, of 11 to 16 narrow vertical single or double-bars across the sides from just below the first spine of dorsal-fin to the first and second or fourth and fifth soft ray of the same fin (vs. 5-7 elongate dark blotches varying in appearance, the narrow vertical bars can occur in C. tendybaguassu, C. minuano and C. missioneira); it differs from C. tendybaguassu by the normal (vs. greatly thickened) lips. The isognathous mouth distinguishes this species from C. missioneira which has the lower jaw longer than the upper jaw; distinguished from C. minuano and C. celidochilus by the absence of a lateral band (vs. present) (Ref. 75870).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00349 - 0.01806), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (15 of 100) .
