The acouchis (Myoprocta) are rodents belonging to the agouti family. They are generally smaller than the common agoutis and have a very short tail (5 to 7 cm), while the common agoutis lack a tail. For this reason the acouchis are also called tailed agoutis.
There are two species of acouchis:
- Green acouchi (Myoprocta acouchy)
- Red acouchi (Myoprocta exilis)
