Dolichotis

Native to the open and arid regions of Argentina, these creatures are one of the larger species within the rodent family, making them stand out both in size and behavior.

Physically, the Patagonian mara resembles a cross between a rabbit and a small deer. It has a robust body and long, slender limbs that facilitate rapid movement across the sparse terrain of its habitat. Its fur is usually a grayish-brown color, which provides excellent camouflage against the earthy tones of the Patagonian landscape. The mara’s head is relatively small compared to its body, with large, rounded ears that enhance its hearing—an essential adaptation for detecting predators.

One of the most intriguing aspects of the Patagonian mara is its locomotion. It moves with a graceful, bounding gait that allows it to cover ground quickly and efficiently, which is crucial for escaping predators. This ability to sprint at speeds of up to 45 km/h (28 mph) is complemented by its endurance, enabling maras to outrun threats over longer distances than many other rodents.

Maras are known for their unusual social and reproductive behaviors. They are monogamous, a rare trait among rodents, which means that they form long-term pair bonds with a single mate. These pairs are often seen together while foraging or resting, displaying signs of affection such as grooming each other. During the breeding season, maras may gather in communal dens, which are shared by several pairs. Each female typically gives birth to one to three offspring, and the young maras are precocial, meaning they are relatively mature and mobile shortly after birth—an important trait that helps them avoid predators.
