Also known as the Patagonian hare, the species is monogamous with pairs staying together for life. The male follows the female wherever she goes, scent-marking her. The main reason for this behavior is most likely the unusually short time frame for successful reproduction to take place, as the females are only fertile for 30 minutes every 3–4 months. The well-developed ears, nose and eyes help them to detect predators. Patagonian maras will bolt at 45 km/h when danger approaches.
