Heartwarming Photos Prove Capybara Can Befriend Every Other Species

If the animal kingdom were a school, this chap would be the most popular student in every class. Meet the capybara - the world's largest rodent, which also appears to be the friendliest critter on earth. The capybara, which can grow to around four feet in length and weigh up to 145lbs, is a highly social semi-aquatic mammal that lives in groups as large as 100, and is native to the forests and marshes of South America.

Capybaras are semi-aquatic, which means that while they live on land they spend a lot of time in the water, hanging out near swamps, rivers and ponds. Capybaras are amazing swimmers, with webbed feet that let them move quickly through the water. They can hold their breath for five minutes at a time, and their ears fold back when they're underwater so they never have to worry about water getting stuck in their ears. The capybara can even sleep underwater, with just its nose above water.
