Q: Can I get random animal names only, without the facts?

Not in one press. Copy the list copies each name with its fact on the line under it, so delete the fact lines after you paste. For a longer list, press Add another until the list holds 20 and copy a few draws in a row. Nothing repeats between them.

Press Pick 5 new animals for five real animals from a checked list of 347, each with one true fact.

Stick insect Disguised as a twig or leaf. The group includes the longest insects in the world.
Tarantula hawk A spider wasp. Its sting paralyzes a tarantula, which becomes food for its larva.
Tardigrade About half a millimetre long with eight legs. It survives drying out, extreme cold and even space.
Termite Often called white ants, but really highly evolved cockroaches. A king and queen pair for life.
Western honey bee Tells hive-mates where food is with a waggle dance. One of the first insects people kept.

How this list was compiled: One Wikipedia article per animal, read as the intro extract through the MediaWiki API (https://en.wikipedia.org/w/api.php?action=query&prop=extracts&exintro=1&explaintext=1&titles=ARTICLE), checked 2026-09-18. Every fact is reworded. Conservation status and population counts are left out because they change. Licence: own work

How it works

This random animal generator draws from 347 real animals, from the aye-aye to the tardigrade, and prints one true fact under each name. Narrow the draw to mammals, birds, reptiles, amphibians, fish, invertebrates, sea animals or farm animals and pets. Take away the ones you do not want and press again.

Pick a random animal, then keep or take away

Five animals show when it opens. Press Pick 5 new animals for five more. On a keyboard the space bar does the same. For a longer list, press Add another at its end; the × on a row makes it shorter. To keep an animal, take the others away with the × at the end of their rows: the next press fills the gaps and leaves what you kept. Nothing repeats until you have seen every animal in the group you chose.

Use it as a random animal wheel

A spinning wheel stops being readable after a few dozen slices, so this page deals all 347 animals as cards. Take the others away with × until one is left, and that animal stands alone in large type, which is what a random animal spinner gives, without the wait. Choose a group in the All animals menu first and the draw stays inside it, handy for a reptile lesson or a sea-themed party.

Where the facts come from

Every line was checked on 18 September 2026 against the opening section of that animal's Wikipedia article, then rewritten in our own words. Sizes, speeds and ages are the article's own figures. We left out anything that shifts from year to year, such as how endangered a species is or how many are left. The full list sits below the tool, so you can read every animal and every fact before using it with a class.

Keep two animals and sketch the creature you would get by crossing them. Add a third ingredient from the random animal part generator.
Cover the names, read a fact aloud and let the room guess the animal. Facts that name a place or a record make the fairest clues.
For a random animal spin wheel feel on a projector, let a student press the button and read out the first animal.
Set a sorting task: show 10 from All animals and ask the class to sort them into the six animal groups. The list under the tool sorts every animal by group, so check the answers there.

Questions and answers

How many animals are in the list?

There are 347: 129 mammals, 72 birds, 36 reptiles, 16 amphibians, 37 fish and 57 invertebrates. Two extra choices in the All animals menu cut across those groups: 70 sea animals, from the blue whale to the barnacle, and 25 farm animals and pets. Every animal is alive today, so no dinosaurs and no dragons.

Is there a random animal generator wheel I can spin?

Not a spinning one. A random animal wheel generator makes you type the slices first, and the labels shrink with every slice you add. Here the list is already built and checked, and the first row of each press is the same one-winner result in a single press. Every animal in the group you chose has the same chance.

What is the difference between this and an animal randomizer wheel?

Most wheels forget what they landed on, so the same slice can win twice in a row. This page remembers: no animal comes back until you have been through the whole list or the whole group, which matters when thirty students each need a different animal. You can also keep a result, take one away or type your own.

Can I get random animal names only, without the facts?

Not in one press. Copy the list copies each name with its fact on the line under it, so delete the fact lines after you paste. For a longer list, press Add another until the list holds 20 and copy a few draws in a row. Nothing repeats between them.

Are the facts true?

Each one was read in the animal's Wikipedia article on 18 September 2026 and reworded, and the source is named under the list. Record claims keep the article's own caution, with words such as known or considered left in. If you spot a mistake, tell us through the contact page and we will check it and fix the page.
