Search — Find Any Animal in Seconds

Whether you know the exact name or just a vague keyword, you can find what you are looking for right away.

The A–Z Index lists every animal article in alphabetical order — the fastest way to find an animal when you already know its name.

If you only remember part of a name, a habitat, or a trait, the keyword search will look across the entire encyclopedia and find matching articles for you.

Every article comes with clear photos, classification info, and an easy-to-read explanation — great for school projects, casual reading, or satisfying your curiosity.

Taxonomy Tree — See How All Animals Are Connected

Explore the animal kingdom through a beautiful visual map that shows how every group of animals is related.

The Taxonomy Tree is one of Animalbook's most popular features. It lets you see the entire animal kingdom at a glance — from broad groups like mammals and insects down to specific orders — all shown in a poster-style map you can explore freely.

Switch between common names and scientific names, show or hide extinct groups, and tap on any branch to jump straight to the animal articles inside it.

You can also check out our Projects page for themed collections and games, or read the Philosophy page to learn about why we built Animalbook.
