Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 13 - 14; Mjukstrålar i analfenan: 11 - 12; Ryggkotor: 34 - 35. Can be differentiated from other members of the genus Leporinus by possessing 4 teeth on the premaxilla and 3 teeth on the dentary yielding the dental formula 4/3. Distinguished also from other species by the following combinations of non-unique characters: lateral line with 36-37 pored scales; transverse series of scales from origin of dorsal fin to lateral line 4; scales from lateral line to base of pelvic fin 4.5-5; series of scales around caudal peduncle 16; lateral line with 3 round dark blotches, the first at vertical through dorsal fin, the second at vertical through adipose-fin origin and the third at base of caudal peduncle (the latter two blotches, particularly the last one, usually small or inconspicuous) (Ref. 75002).
Body shape (shape guide): fusiform / normal.
Adults inhabit lentic environments such as lagoons or borrow pits (Ref. 75002). Distinct pairs breed on densely grown weedy places (Ref. 205).
