You know that animal that always looks like it’s on a nature retreat, soaking in hot springs with oranges on its head, hanging out with ducks, or sitting perfectly still while monkeys climb all over it? That’s the capybara — and yes, it’s as laid-back as it looks.
Let’s dive into the strange and gentle world of the capybara, the internet’s favorite giant rodent.
What is a Capybara?
A capybara is a semi-aquatic mammal native to South America and — plot twist — it’s the largest rodent in the world. It’s part of the Caviidae family, which also includes guinea pigs, but think of the capybara as the cool older cousin who went to live by the river and now gets along with everyone.
Capybaras are social, relaxed, and deeply nonchalant in a way that makes them fascinating to researchers and meme-makers alike. They’re typically found near rivers, lakes, marshes, and wherever there’s enough water for a solid splash and enough grass for an endless buffet.
Capybara Size
Let’s talk scale. Capybaras aren’t just “big guinea pigs.” They’re borderline dog-sized. Adults typically measure about 4 feet long (1.2 meters) and stand about 2 feet tall (50–60 cm) at the shoulder. They can weigh anywhere between 77 and 145 pounds (35–66 kg).
To put that in perspective: if you’ve ever picked up a labrador and thought, “This could use more webbed toes and less barking,” you’re capybara-ready.
Capybara Diet
Capybaras are strict herbivores with very simple tastes. They eat:
• Grasses (their main course)
• Aquatic plants
• Fruits and veggies if available
• Tree bark and reeds in lean seasons
Fun twist: They also practice coprophagy — that is, they eat their own poop. Why? To re-digest fibers and get extra nutrients from their meals. Gross? A little. Smart? Absolutely.
Is Capybara a Pig or a Rat?
Capybaras are neither, and also somehow… both?
They’re not pigs, despite the stocky build and love of mud. Pigs are ungulates (hoofed animals), and capybaras are rodents — like mice, squirrels, and beavers. But they’re not rats either. Rats belong to a completely different rodent subfamily.
Capybaras are closer to guinea pigs and rock cavies. They’re rodents, yes — but they’re in their own league.
Is a Capybara a Good Pet?
It depends on your definition of “good.” Capybaras are:
• Affectionate with humans if well-socialized
• Extremely social, so they need company (other capybaras ideally)
• Semi-aquatic, so you’ll need a pool or pond
• Very active, and they require a lot of space — not a backyard, more like a pasture
Oh, and they’re illegal or restricted as pets in many places (like California and New York). So before you get emotionally invested in the idea of cuddling with a pool-dwelling, grass-munching creature that looks like a loaf of bread with legs, check your local laws.
Why Is Capybara So Famous?
A few things happened:
• They’re absurdly photogenic. Capybaras have a permanent “resting calm face.” That, combined with their water-loving habits, makes for perfect viral content.
• They’re surprisingly tolerant of other animals. Birds perch on them, monkeys groom them, and cats nap next to them.
• Japanese onsens (hot springs) feature capybaras soaking in hot water with citrus fruit floating around them, and honestly, humans have been chasing that exact vibe for centuries.
They became a meme, then a trend, then an icon — and somehow, still remained chill about the whole thing.
Is Capybara Really Friendly?
Capybaras are famously unbothered. They’re not affectionate in the way dogs are — they don’t fetch or lick faces — but they’re genuinely peaceful, even toward strangers (animal or human).
In the wild, they live in groups of 10–30, communicate with barks, purrs, and whistles, and form bonds through grooming and huddling. In captivity, if they’re treated well and given companionship, they’re approachable, gentle, and even cuddly.
But remember: capybaras are still wild animals. Friendly? Yes. Domesticated? No. Respect their space, and you’ll be rewarded with a very chill, very fuzzy friend.
