The
maras (
Dolichotis) are a
genus of the
cavy family. They are the sole representatives of the subfamily
Dolichotinae. These large relatives of
guinea pigs are common in the
Patagonian steppes of Argentina, but also live in Paraguay and elsewhere in South America. Maras are the fourth-largest
rodent in the world, after
capybaras,
beavers, and
porcupines, reaching about in height.
