CAN YOU ACTUALLY TELL A CAPYBARA FROM A WOMBAT, BEAVER, NUTRIA, OR GUINEA PIG?

Twelve rounds. Five difficulty levels. It ends with a photo of fur and nothing else. You're going to feel things.

Capybaras are the world's largest rodents and somehow the internet still mixes them up with wombats, beavers, nutrias, and guinea pigs on a daily basis. This starts easy — whole animals, good lighting — and then the photos start losing parts. By the end you get an ear. Then a nose. Then a patch of fur and our sincere best wishes.

The playable version needs JavaScript. Here is the whole quiz as plain text — 12 questions and 5 possible verdicts.

  1. Question 1. Pick the capybara.

    Whole animals, good light, nothing hidden. This is the part where you feel good about yourself.

  2. Question 2. Again. Pick the capybara.

  3. Question 3. One of these is a capybara.

  4. Question 4. Capybara. Find it. Last easy one.

  5. Question 5. Just heads now. Pick the capybara.

    Bodies gone. No size cue, no posture, no water to give it away. A capybara head is long and blunt, with the eyes and ears pushed high and far back.

  6. Question 6. Still heads. Still one capybara.

  7. Question 7. Head only. Do not get sentimental about the wet ones.

  8. Question 8. One ear. Pick the capybara.

    This is where it stops being a vibe check. Capybara ears are small, rounded, and set high on the skull, with coarse hair running right up to them — the whole face is built to stay above the waterline.

  9. Question 9. Another ear. Same job.

  10. Question 10. A nose. Somewhere in here, a capybara.

    Bright orange incisors are a nutria and beaver signature. Capybara teeth are much paler, and the muzzle is broad and squared off rather than pointed.

  11. Question 11. Muzzle only. This is the last fair question.

  12. Question 12. Fur. Just fur. Good luck.

    No face, no ears, no outline. Capybara hair is long, coarse, and sparse enough that you can see skin through it. Everything else here is denser or wetter. We did warn you.

How the scores read

  • Capybara-Certified — Twelve out of twelve, including the fur. You are not fooled by a wombat, a beaver in good lighting, or a guinea pig with delusions, and you correctly identified a capybara from hair alone. The capybaras have noted your work. You may now claim Capybara-Certified status, which carries no benefits except the soft confidence of being right.
  • Solidly Capybara-Adjacent — You held it together through the heads and most of the ears, and then something small went wrong. Probably the fur. Possibly a wombat. This is a genuinely good score — the back half of this quiz is not designed to be survived intact. The capybaras are willing to acknowledge you in public. Provisionally.
  • Field Guide Curious — Whole animals: fine. Cropped animals: less fine. You know the shape of a capybara but not yet the parts, which is the exact gap the comparison guides below exist to close. Come back after reading one. The score will move.
  • Trying. Truly. — You guessed. Some of them were right. The capybaras do appreciate the effort, in the way that you appreciate it when someone remembers your name but not your job. We recommend spending more time near calm bodies of water. It will help.
  • Brave. Just Brave. — This was hard for you, and we want to acknowledge that. The capybaras are not angry. They are just disappointed. The good news: knowing nothing about capybaras and still finishing a twelve-round identification quiz that ends in a photo of fur is, in its own way, deeply capybara-coded. You're closer to one than you think.

FAQ

What is the easiest way to tell a capybara from a nutria?
Teeth and tail. A nutria has bright orange incisors and a long, round, rat-like tail it drags behind it. A capybara's incisors are much paler and it has essentially no visible tail at all — just a rounded rump. In person, size settles it: a capybara runs 35 to 66 kg, a nutria rarely clears 9 kg.
How do capybara ears differ from a beaver's or a wombat's?
Capybara ears are small, rounded, and set high and far back on the skull, alongside the eyes and nostrils, so all three stay above the waterline while the animal floats. Beaver ears are smaller still and nearly buried in dense fur. Wombat ears are more triangular and stand further out from the head.
Is a capybara just a giant guinea pig?
They are cousins, not the same animal. Both are caviomorph rodents, but a guinea pig weighs about a kilogram and a capybara can pass 60. Capybaras also have partially webbed feet and a semi-aquatic life that guinea pigs do not.
Why is the fur round in this quiz so hard?
Because it is meant to be. Capybara hair is long, coarse, and sparse enough that skin shows through it, which is a real identification cue — but it is one you have to have looked at before. If you got that round right by reasoning rather than luck, you have earned it.
Do capybaras have tails?
Barely. A capybara has a vestigial tail — a small nub, usually hidden under the fur. Any long tail in a photo means you are looking at a nutria, a beaver's paddle, or something else entirely.

Are Capybaras Legal in Quebec? The Only Province That Names the Animal

Every other province in Canada answers this by omission. Quebec put Hydrochoerus in a schedule by genus, marked it as requiring a permit, and marked the cavies a few rows above it as needing none. It is the clearest provincial answer in the country, and it is a qualified yes.

Are Capybaras Legal in British Columbia? The Alien Species List Has No Rodents At All

BC built a controlled alien species regime after a tiger attack, aimed it at animals that can hurt people, and never put a single rodent on it. That leaves the capybara outside the province's main exotic-animal law and inside a municipal patchwork with no shared template. Surrey prohibits it outright. Victoria has no species list at all. Vancouver, remarkably, appears not to prohibit it.
