The Ultimate Guide to the World's Chillest Animal
Hydrochoerus hydrochaeris — which literally means "water pig" in Greek! They're the world's largest living rodent. Yes, they're related to guinea pigs, mice, and hamsters — just MUCH bigger!
Imagine a dog the size of a Labrador, but rounder and with a giant square nose. They stand about 1.5 feet tall at the shoulder, stretch up to 4 feet long, and weigh between 75 and 150 pounds. Some big boys hit 174 lbs!
Their eyes, ears, and nostrils are all on the top of their head — like a hippo! This means they can see, hear, and breathe while almost completely underwater. They also have webbed feet for swimming!
Capybaras are strict vegetarians! They eat:
They eat 6-8 pounds of plants every single day — that's like eating 24 heads of lettuce! They graze mostly in the morning and evening when it's cooler. Their teeth never stop growing, which keeps them from wearing down from all that chewing.
Okay, this is kinda icky but scientifically awesome: capybaras eat their own poop! It's called coprophagy. By digesting their food twice, they get way more nutrients out of it. Lots of animals do this — rabbits too!
Capybaras don't sleep through the night like we do. They take lots of short naps throughout the day and night — about 12 hours total! This is called polyphasic sleep, and it helps them stay alert for predators.
Here's the wildest part: capybaras can sleep while floating in water with just their nose sticking out to breathe! They also nap on grassy riverbanks or under shady trees. Imagine falling asleep in a pool — that's Tuesday for a capybara.
They often sleep in big cuddle piles for warmth and safety. While some capybaras snooze, others stand guard watching for danger. Teamwork!
Capybaras are super social — they almost NEVER live alone! A typical group has 10-20 capybaras, but during dry season when water is scarce, groups can grow to 50 or even 100!
Each group has a dominant male — usually the heaviest one. He gets the safest spot in the middle of the group. The other males hang around the edges and act as lookouts for danger. They bark loudly when they spot a predator!
Nope! Capybaras don't have just one partner. The dominant male tries to be the main partner, but others get chances too. Fun fact: mating always happens in the water! If a female isn't interested, she just dives underwater and swims away. 😎
Mama capybaras are pregnant for about 5 months and usually have 4 babies at a time (but up to 8!). Babies can walk and eat grass within their first week! The coolest part: ALL the moms in the group help raise ALL the babies. It takes a village!
Capybaras are surprisingly chatty! They make all sorts of sounds to talk to each other:
Sharp alarm call when danger is near
🔊 Tap to hear!
Happy, content, and relaxed
🔊 Tap to hear!
Keeping in touch with the group
🔊 Tap to hear!
Teeth-chattering when annoyed
🔊 Tap to hear!
Baby capybaras calling mom
🔊 Tap to hear!
General conversation between friends
🔊 Tap to hear!
Capybaras live in South America — from Panama all the way down to Argentina. They NEED to live near water, so you'll find them near rivers, lakes, ponds, marshes, and swamps in savannas and rainforests. Water is their best friend — it keeps them cool, helps them hide from predators, and is basically their second home!
