Howler monkeys (genus Alouatta) comprise some 12 species of fruit-, leaf-, and flower-feeding New World primates that range from southern Mexico through southern Argentina and Brazil. They are arboreal and sexually dimorphic (and sexual dichromatic in two species). Some characteristics shared with other Atelinae (species in the same subfamily as Alouatta) are large body mass, a prehensile tail, and modified hyoid bone that allows them to perform their howling.
