Myleus is a genus of serrasalmids from South America, where found in the Amazon, Orinoco and São Francisco basins, as well as the river basin of the Guiana Shield.[1] They are found in rivers with moderately or fast-flowing water, including rapids.[2] They are primarily herbivores, but also take some animal matter.[2] Depending on the exact species, they reach up to 12–42 cm (0.4–1.4 ft) in standard length, and the adult males have a double-lobed anal fin and filamentous extensions on the dorsal fin.[2] Their strong teeth means that larger individuals can inflict severe bites on humans.
Species
There are currently 6 recognized species of Myleus.[1][3] Several others have been moved to the genus Myloplus.[1]
