List of dasyproctids

Dasyproctidae is a family of mammals in the order Rodentia and part of the Caviomorpha parvorder. Members of this family are called dasyproctids and include agoutis and acouchis. They are found in Mexico, Central America, and South America, primarily in forests, though some species can be found in savannas. They range in size from the green acouchi, at 30 cm (12 in) plus a 4 cm (2 in) tail, to the black agouti, at 76 cm (30 in) plus a 4 cm (2 in) tail. Dasyproctids are herbivores and primarily eat fruit, vegetables, and succulent plants. No dasyproctids have population estimates, though the Ruatan Island agouti is categorized as an endangered species and the Mexican agouti is categorized as critically endangered.

The fifteen extant species of Dasyproctidae are divided into two genera: Dasyprocta contains thirteen species of agoutis, while Myoprocta contains two species of achouchis. A few extinct prehistoric dasyproctid species have been discovered, though due to ongoing research and discoveries, the exact number and categorization is not fixed.
