Behavior

Green acouchis are diurnal, surface dwelling rodents and have a complex array of behavior patterns relating to social interaction. In addition, they are food hoarders, employing a scatter hoarding strategy.

Reproduction

Female acouchis have an average oestrus cycle length of around 43 days and have a set breeding season between autumn-spring with a 99-day gestation. Females produce small litters of relatively
