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.

The brown mammals can often be spotted with birds hitching a lift on their backs. Images of the furry creature interacting with just about every other animal you can imagine - in this case a baby goat - have been doing the internet rounds of late, and it's easy to see why. The capybara is quite closely related to the guinea pea, and this one seems to blend right in. While uncommon, the capybara's intelligence and gentle nature means they can be kept as pets.
