Capybara

Capybaras are the largest rodents on Earth—and some of the most social. Native to South America, these gentle grazers are often found lounging near rivers, ponds, and marshes in groups as large as 40. 

Capybaras are excellent swimmers and can stay underwater for up to five minutes to avoid predators or simply cool off. Their semi-aquatic lifestyle means they rely on healthy freshwater ecosystems for survival, reproduction, and protection. 

Capybaras graze on grasses and aquatic plants. They are one of the few mammals that re-ingest their feces to help extract every last bit of nutrition. As they move through their environment, they create feeding opportunities for birds and other species, making them an important part of the ecosystem. 

Females give birth to 2-8 young after about five months. The babies are up and grazing within a week but are weaned at three months. Remarkably, mothers and other females care for the young together, helping to raise the next generation in communal creche groups.
