Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11 - 12; Spine anali: 0; Raggi anali molli: 9 - 10; Vertebre: 31 - 33. Differs from other Cyphocharax (except aspilos) by the absence of multiple series of longitudinal patterns of dark pigmentation on body, the absence of a large spot of pigmentation on the body, the absence of a large spot of pigmentation on the dorsal fin, the absence of a rotund spot or longitudinal stripe of dark pigmentation on the midlateral surface of the caudal peduncle, the number of lateral line scales, and the depth of caudal peduncle of 0.13-0.15 of SL (Ref. 11334).
Inhabits rivers or creeks of moderate current between 20 and 10 m elevation. Abundant in shallow waters over sand or mud bottoms where it feeds on detritus, diatoms and algae (Ref. 36880). Found in swamps or marshes and rivers (Ref. 26543). Feeds exclusively on detritus (Ref. 26543).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.01320 - 0.03627), b=3.00 (2.87 - 3.13), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
