Descrição suscinta Morfologia | Morfometria

Espinhos dorsais (total): 9 - 11; Espinhos anais 14-15. Subcylindrical body (Ref. 27292, Ref. 36901). Upper and lower jaw of equal length (Ref. 36901, Ref. 42907). Number of dorsal finlets: 9-11 (Ref. 42908, Ref. 51884). Dorsal fin origin well behind pectoral fin (Ref. 4967, Ref. 42873). Ganoid scales (Ref. 27292, Ref. 42904): 58-65 lateral line scales, 38-44 scales around body, 22-27 predorsal scales (Ref. 2970, Ref. 11970, Ref. 42907, Ref. 42908). Dorsal side grey-brown colored, marbled with clear whitish spots (Ref. 11970), the belly is white to yellowish (Ref. 27292). Head finely reticulated (Ref. 42873, Ref. 42901). Fins with white spots alternating with dark spots, forming a continuous bar (Ref. 11970).

Biologia     Glossário (p.ex. epibenthic)

Facultative air-breathing (Ref. 126274); Inhabits calm waters of swamps and rivers (Ref. 11970). It feeds on worms and insect larvae when young, but takes larger food, mainly fish, when adult (Ref. 27292). It mainly hunts at night (Ref. 27292). In general they are more or less solitary fish and do not form schools (Ref. 27292).

Ciclo de vida ou comportamento de acasalamento Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Male starts with the courtship and is the active partner (Ref. 1672). The male makes from the anal fin a sort of cup and the female lays the eggs in this cup (Ref. 1672). The male then spreads the eggs so that they attach, e.g., to plants.

Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.05 (2.85 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.7   ±0.60 se; based on food items.
Resiliência (Ref. 120179):  Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec=200-300; tmax likely >= 20).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
