Descrição breve Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 10; Espinhos anais: 0; Raios anais moles: 15. Diagnosis: large fang-like teeth overlapping the jaws when the mouth is closed; gill-rakers long, about equal to the length of gill filaments; body generally > 22% of SL (Ref. 28714). 43-53 scales in lateral line; 2 scale rows between lateral line and scaly process at pelvic-fin bases; eye < 70% of interorbital space (Ref. 2880, 81279). Dorsal-fin origin at about same level as pelvic-fin insertions (Ref. 2880, 80290, 81279). Gill rakers few (5-9/9-12) but rather long (Ref. 2880, 80290, 81279), about equal to the length of gill filaments (Ref. 28714). Tips of adipose and dorsal fins black; forked edge of caudal fin black (Ref. 2880, 80290, 81279). Dark caudal fin coloration may also extend unto median caudal rays, forming crescent-shaped blotch (Ref. 80290, 81279). Dark longitudinal streaks present above the lateral line (Ref. 28714).
Prefers warm, well-oxygenated water, mainly larger rivers and lakes; all but the largest form roving schools of like-sized fish; aptly described as fierce and voracious; diet increasingly piscivorous, becoming exclusive fish feeders when above 90-100 mm length; feeds on whatever prey is most abundant but Brycinus, Micralestes, Barbus, and Limnothrissa are favored (Ref. 7248, 52193). Piscivorous, but may also eat Caridina and insects (Ref. 28714). Useful food fish in some areas (Ref. 4967).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00834 - 0.01314), b=3.03 (2.97 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245).
Nível Trófico (Ref. 69278): 4.4 ±0.0 se; based on diet studies.
Generation time: 3.7 (3.0 - 5.0) years. Estimated as median ln(3)/K based on 14 growth studies.
Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.20-0.30; tmax=11).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
Nutrients (Ref. 124155): Calcium = 69.1 [24.4, 163.4] mg/100g; Iron = 1.47 [0.76, 3.56] mg/100g; Protein = 19.5 [17.4, 21.7] %; Omega3 = 0.462 [0.179, 1.253] g/100g; Selenium = 75 [30, 165] μg/100g; VitaminA = 30.6 [9.0, 102.8] μg/100g; Zinc = 0.887 [0.602, 1.339] mg/100g (wet weight);
