Tamanho / Peso / Idade
Maturity: Lm ?  range ? - ? cm
Max length : 41.0 cm SL macho/indeterminado; (Ref. 7248)
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 60 - 80; Raios anais moles: 56 - 63; Vértebras: 58 - 61. Characterized by its lateral line which appears as a thick white band; barbels extremely short. Head long, broad and flattened. Frontal fontanelle long and extremely narrow. Occipital fontanelle rather small. The `dermosphenotic' and supraorbital bones are separated. Tooth plate extremely broad. Pectoral spine straight and robust. Suprabranchial organ well developed but not completely filling the chamber.
Facultative air-breathing (Ref. 126274); Occurs in well-vegetated sluggish river channels and floodplain lagoons. Breeds during the summer rainy season (Ref. 7248). Eats invertebrates and, when older, other fishes (Ref. 7248, 78218).
