Habitat and Ecology [top]

Habitat and Ecology:This species is found in mature evergreen and semideciduous forest, and dense, viney second growth, usually near rocks, caves, or cliffs (Reid 1997).

It is nocturnal and semiarboreal. Though its movements are usually slow and deliberate, this large rat can travel with great speed and agility on vines and branches. Little is known of its diet; the stomach of an animal from Veracruz contained vegetation resembling lichen or bark (Hall and Dalquest 1963 in Reid 1997). Its gestation is about 40 days, and litter size averages 2.5 young (Herlm 1975 in Reid 1997).
