What Is a Capybara?

A capybara is the world’s largest rodent. Yes, it is related to mice and guinea pigs — but it is about the size of a large dog! A fully grown capybara can weigh between 35 and 66 kilograms (that is 77 to 145 pounds), and grow up to about 1.2 meters (4 feet) long. They are native to South America, where they live in groups near rivers, lakes, ponds, and swamps.

The name “capybara” comes from the Tupi language spoken by indigenous people of Brazil, and it roughly means “master of the grasses” or “one who eats slender leaves.” This makes perfect sense, because capybaras spend most of their day quietly munching on grass and water plants!

What Do Capybaras Look Like?

Capybaras look a bit like a very large guinea pig crossed with a hippopotamus! They have a barrel-shaped body covered in coarse, brownish-reddish fur. Their head is large and square-shaped with small, rounded ears, small eyes, and a broad, flat nose. Their legs are short and sturdy, and they have slightly webbed feet — perfect for swimming!

One of the most charming things about capybaras is their facial expression. They always seem to look incredibly calm and content — like they have absolutely no worries in the world. That peaceful “I am fine, everything is fine” face is a big reason why people find them so endearing.

Where Do Capybaras Live?

Capybaras are found throughout Central and South America — in countries like Brazil, Venezuela, Colombia, Peru, Argentina, and Bolivia. They love living near water and are semi-aquatic, which means they spend time both on land and in the water. In fact, capybaras are excellent swimmers! They can stay underwater for up to 5 minutes to hide from predators like jaguars, caimans, and anacondas.

Capybaras live in social groups of around 10 to 20 animals, though groups of up to 100 have been spotted during dry seasons when many animals gather near the same water source. They are very social and do not like being alone — a capybara by itself can become stressed and sad.

Why Are Capybaras So Friendly?

This is the big question! Capybaras are famously non-aggressive and calm. Scientists and animal experts believe there are a few reasons for this:

They are naturally social animals: Capybaras evolved to live in large groups, so they are naturally comfortable being around others — including animals from different species.
They communicate peacefully: Capybaras use a range of gentle sounds — purrs, barks, whistles, and clicks — to talk to each other. They rarely show aggression.
They are not territorial: Unlike many animals that defend their space aggressively, capybaras are generally relaxed about sharing their environment.
They groom each other: Grooming is a way many animals show trust and friendship, and capybaras do this regularly within their groups.

This natural friendliness means that other animals often feel comfortable around capybaras too. Birds land on their backs to eat insects. Monkeys ride on them. Baby animals of all kinds curl up next to them for warmth. Capybaras truly are the “chill friend” of the animal kingdom!

Capybaras and Their Animal Friends

One of the most delightful things about capybaras is the wide variety of animals they peacefully coexist with. There are countless photos and videos showing capybaras hanging out with:

Birds — especially yellow-headed caracaras and giant cowbirds, which sit on capybaras to eat parasites from their skin (like a free spa service!)
Monkeys — which ride on their backs and groom them
Ducks and geese — which sit calmly on top of them
Dogs and cats — in captivity, capybaras often become best friends with domestic pets
Baby animals of all kinds — chicks, puppies, kittens, and even baby crocodiles have been photographed resting on capybaras

In Japan, where capybaras have become especially popular, many zoos set up outdoor hot spring baths for capybaras in winter. Images of capybaras relaxing in steaming hot water with fruits floating around them — looking completely blissful — go viral every year without fail!

What Do Capybaras Eat?

Capybaras are herbivores, which means they only eat plants. Their diet consists mostly of grasses and aquatic plants. They are grazers, much like cows or horses, spending a significant portion of their day slowly eating vegetation. A capybara can eat up to 3 kilograms of grass per day!

Because grass is not very nutritious, capybaras have a special digestive adaptation: they eat their own droppings in the morning. This might sound strange, but it allows them to digest their food twice and get maximum nutrition from it. Many other herbivores, including rabbits, do the same thing!

Can You Keep a Capybara as a Pet?

Capybaras have become popular exotic pets in some countries, and it is easy to see the appeal — they are gentle, social, and absolutely adorable. However, they are not ideal pets for most people. Here is why:

They need constant companionship — a single capybara alone will be unhappy. You would need at least two.
They need access to a large body of water to swim in every day.
They need a lot of outdoor space to graze and roam.
They are illegal to own in many places, including several US states and countries in Europe.
Their diet and veterinary care needs are very specific and can be costly.

If you truly love capybaras, the best way to enjoy them is by visiting them at accredited zoos and wildlife parks, or supporting conservation organizations that protect their natural habitat in South America.

Fun Capybara Facts for Kids

Capybaras can run as fast as 35 km/h (22 mph) — about as fast as a human sprinting at top speed!
They have continuously growing teeth, like all rodents, which is why they need to chew so much.
Capybaras can sleep in the water — keeping just their nose above the surface to breathe.
They have scent glands on their nose that they use to mark territory and communicate with other capybaras.
A baby capybara is called a pup. Capybara pups can walk, swim, and eat grass within hours of being born!
In Japan, the capybara is so popular it has its own national holiday — Capybara Day.

Capybaras on the Internet

In recent years, capybaras have exploded in popularity online. Memes featuring their calm, unbothered expressions have spread across social media worldwide. One particularly famous trend showed capybaras relaxing in various impossible situations with the tagline “Capybaras don’t have enemies.” This resonated with millions of people who found the idea of a creature that is genuinely at peace with the world deeply relatable — and very funny.

The capybara’s internet fame has actually been great for awareness of South American wildlife and ecosystems. Many people who learned about capybaras through memes have since become interested in conservation issues affecting their natural habitat, such as wetland destruction and habitat loss.

Final Thoughts

The capybara is proof that being kind, calm, and social makes the whole world love you — whether you are a human or a 65-kilogram rodent! These amazing animals remind us that friendliness is a superpower. They get along with nearly everyone, they never seem to panic, and they make every creature around them feel welcome.

Next time you are feeling stressed, just think: What would a capybara do? The answer is probably to find a warm pool of water, munch some grass, and let a duck sit on your head. Works every time! Tell us in the comments — have you ever seen a capybara up close?
