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 capybara holds the title of the largest rodent in the world. They are usually between 50 to 60 centimeters tall and 106 to 134 centimeters long – as big as a medium-sized dog. They're heavy too, weighing in between 35 and 66 kilograms. Since they are rodents, like mice and rats, the capybaras' front teeth keep growing for their whole lives, but the teeth get worn down from all the eating they do. Capybaras are usually friendly but people who have been bitten by them report their teeth as being sharp.
