Myoprocta acouchy pratti

Range: East of the Andes in southern Colombia, eastern Ecuador, northern Peru, Amazon Basin of Brazil

Habitat: Tropical rain forests in cool lowland forests, along stream banks, and in thick brush

Conservation status: Not threatened


  • • Sometimes called green acouchis; live in colonies of 2-7, usually parents and youngsters
    • Diurnal (active in daytime) rodents; orange incisor teeth grow continuously throughout life
    • Herbivores – feed on a wide variety of fruits, succulent plants, nuts, leaves, stems, and roots; sit upright to eat and bury fruits in scattered places for future use, which helps disperse seeds
    • When in danger, they generally freeze in place.
    • Sort-haired tail, which is white underneath, is used as a signaling mechanism.
    • Reach sexual maturity at 8 to 12 months, and breed primarily in the summer.
    • Gestation is approx. 99 days, and generally there are two in a litter. The newborn are fully furred and have their eyes open (precocial).
    • Acouchi mothers communicate with their offspring through vocalizations, with infants following their mothers more when she vocalized as compared to when she was quiet. Scientists believe that this is a way for the infant to know the mother’s location.
    • Can live up to ten years in captivity. Lifespan in the wild is shorter because of predation, disease, and competition for resources.
    • Green acouchis can be agricultural pests on native gardens by eating cassava and peanuts (Anderson and Jones, 1984).
