About Capybaras

The world's most universally loved animal

Capybaras are semi-aquatic rodents native to South America, and they hold the remarkable distinction of being the world's largest living rodent. Adults typically weigh between 77 and 150 pounds and stand about two feet tall at the shoulder.

What makes them truly extraordinary isn't just their size — it's their temperament. Capybaras are famously calm, social, and tolerant, and have become beloved internet icons celebrated for their zen-like equanimity. They are genuinely friends with nearly every other species they encounter.

Every Animal's Best Friend

Capybaras are famously tolerant of other species — monkeys, birds, ducks, cats, dogs, and even caimans have been documented resting on or with capybaras in the wild and in captivity. No one knows exactly why, but they simply don't seem to mind.
🦷

Teeth That Never Stop Growing

Like all rodents, capybaras have hypsodont teeth that grow continuously throughout their lives. Their diet of tough grasses keeps them worn down naturally — without constant grazing, their teeth would grow to dangerous lengths.
🌊

Born Swimmers

Capybaras are semi-aquatic and can stay submerged for up to five minutes. Their eyes, ears, and nostrils are positioned near the tops of their heads — letting them see, hear, and breathe while almost entirely underwater.
🗣

A Complex Vocabulary

Capybaras communicate with a rich repertoire of sounds including purrs, barks, whistles, clicks, and a distinctive "coo-coo" contact call. Different calls signal alarm, contentment, submission, and social bonding within the herd.

Classified as Fish by the Vatican

During the 16th century, Catholic missionaries in Venezuela petitioned the Vatican to classify capybaras as fish — allowing them to be eaten on Fridays and during Lent. The Vatican agreed, and the tradition of eating capybara during holy days persists in parts of Venezuela today.
👶

Large Litters, Fast Developers

Capybara litters typically contain 4–5 pups, though up to 8 have been recorded. Unlike many rodents, capybara pups are born fully furred and with eyes open — and can walk, swim, and graze within hours of birth.
