Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 2; Mjukstrålar i ryggfenan (totalt) : 9; Taggstrålar i analfenan: 3 - 5; Mjukstrålar i analfenan: 21 - 27. Possesses a humeral spot shaped as an oval or inverted teardrop, occupying not less than a quarter of the height of the body; caudal peduncle with a black spot covering between one third and almost the totality of its depth (Ref. 52916).

Attains a length of around 20 cm. As indicated by its dentition and body form, it is a formidable predator which feeds exclusively on fish. A ubiquitous species, but frequently found throughout the length of waters with moderate flow. Reproduction begins with the onset of the rainy season (Ref. 12225).
