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 45 cm in height.
Two species of maras are recognised, the Patagonian mara (Dolichotis patagonum), and the Chacoan mara (Dolichotis salinicola).
Diurnal rodents, widespread in South America, especially in Argentina, where sheep farming, the introduction of the hare with his disease and the rapid spread have resulted in a reduction of the two species.
Females give birth to two to five children and during periods of gestation spend much of the day in search of food while males if they remain on the lawns, on the alert for the arrival of predators.
Feeding:The mara can survive several days without water, probably because it draws the liquid from the vegetables you eat and little urine able to call in the cycle body water several times.
