Size: The head and body length of bats in the genus Pteralopex is 162 - 275 mm (6.4 - 11"). Habitat: As a rule the genus Pteralopex is confined to primary forest (Bowen-Jones et al. 1997). Diet: The cusp-toothed fruit bat probably has a similar diet to the other species of the genus, which is predominantly based on nuts. This is based on the generic feature of specialist dentition. As a rule the genus is confined to primary forest. (Bowen-Jones et al. 1997)
