See text Maras, subfamily Dolichotinae, are a group of rodents in the family Caviidae.

[1] 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 may amble, hop in a rabbit-like fashion, gallop, or bounce on all fours.

If they spot danger, the young rush below ground into a burrow, and the adults are left to run to escape.

Maras may even change their habits from coming out in day to becoming nocturnal, simply to avoid social interaction.
