Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais (total) : 71 - 94; Raios anais : 60 - 89; Vértebras: 56 - 61. Diagnosis: Head rectangular in dorsal outline; snout broadly rounded; eyes dorsally located; frontal fontanelle `knife-shaped'; occipital fontanelle very long and oval-shaped; the `dermosphenotic' and supraorbital bones become joined in specimens of 80-90 mm standard length; tooth plates relatively small; dorsal and anal fins not confluent with caudal fins; gill rakers relatively long, slender and distantly set; openings of the secondary sensory canals arranged in regular pattern on the flanks (Ref. 248). Characterised by a relatively small, short head, 4-5 times in standard length, long barbels reaching to behind the head, and an elongated slender body with a long anal fin (Ref. 52193).

Facultative air-breathing (Ref. 126274); Lives in vegetated areas in shallow and swampy places around the lake. Occasionally found in cataracts, hiding under rocks (Ref. 248). The species is omnivorous (Ref. 78218) and feeds on insects (Coleoptera, ants, Chironomid larvae) (Ref. 248 & 5595), plant seeds and other fishes (Ref. 78218).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00556 - 0.01882), b=3.03 (2.87 - 3.19), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.5 ±0.52 se; based on food items.

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
