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.[1] Specimens of this species is frequently found in acid clear or black waters. They usually feed on aquatic insects, small fish, and fruits.[2]
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.[3]
P. denticulata grows to about 20.0 cm (7.9 in) in TL.[1] It has 62 chromosomes.[3] This fish possesses powerful dentition that can cause serious bites. It has scales.[1]
