Mara (mammal)

Description

Maras have stocky bodies, three sharp-clawed digits on the hind feet, and four digits of the fore feet. Maras have been described as resembling long-legged rabbits; while standing, they can also resemble a small ungulate. Patagonian maras can run at speeds up to 29 km/h. The Patagonian species can weigh over 11 kg in adulthood. The average weight of adult male Patagonian maras is 8.3 kg and in adult females is 7.75 kg. Meanwhile, the Chacoan mara, though still large for a rodent, is much smaller, weighing around 1 to.

Most maras have brown heads and bodies, dark (almost black) rumps with a white fringe around the base, and white bellies.

Maras may amble, hop in a rabbit-like fashion, gallop, or bounce on all fours. They have been known to leap up to 6 ft.

Maras mate for life, and may have from one to three offspring each year. Mara young are very well-developed, and can start grazing within 24 hours. They use a crèche system, where one pair of adults keeps watch over all the young in the crèche. If they spot danger, the young rush below ground into a burrow, and the adults are left to run to escape.

Interaction with humans

Patagonian maras are often kept in zoos or as pets, and are also known as "Patagonian cavies" or "Patagonian hares". They can be quite social with humans if raised with human interaction from a young age, though they avoid people in the wild. Maras may even change their habits from coming out in day to becoming nocturnal, simply to avoid social interaction.
