Dicas de identificação

1. 1

   Body Shape and Coloration

   Look for the deep, compressed, silvery body. The most definitive feature is the broad, vertical black bar in the middle of the body, which is very clear in juveniles and subadults. This bar distinguishes it from many other Myloplus species.

2. 2

   Dentition

   If possible to observe, the small, molar-like teeth are characteristic of its herbivorous diet, differentiating it from piranhas (Serrasalmus spp.) which have sharp, pointed teeth.

3. 3

   Fin Morphology

   Note the long anal fin and the forked caudal fin. The overall fin shape and ray counts can be used for precise identification by ichthyologists.
