Pygopristis denticulata is a species of serrasalmidae. It is a rare South American fish found in the Orinoco River basin, north and eastern Guiana Shield rivers, and tributaries of the lower Amazon River. Specimens of this species is frequently found in acid clear or black waters. They usually feed on aquatic insects, small fish, and fruits.
P. denticulata has pentacuspid teeth and a middle cusp that is usually only slightly larger than the other cusps. This is unlike the piranhas, which have tricuspid teeth with a larger middle cusp, making the teeth appear triangular.
