It is found in the northwestern Amazon in southern Venezuela, eastern Colombia, eastern Ecuador, western Brazil and northeastern Peru. There is also a disjunct population in the Magdalena River Valley of northern Colombia. The black agouti weighs 3.5–6 kg (7.7–13.2 lb). It is overall black grizzled white, and the throat is white. Like other agoutis, the black agouti is diurnal, lives alone or in pairs, and feeds on fruits and nuts.
They are found in forests, thick brush, savannas and cultivated areas.
