The amazing world of animals is on every part of the earth - The deepest ocean, the highest mountain, the darkest forests to the sunniest beaches.

There is no place animals cannot be found, and depending where on earth you look, there are different animals, like Hedgehogs in Europe, Zebras in Africa and Koalas in Australia.

There are even animals older than US! They have evolved through time, and scientists say that dinosaurs may not have become extinct - they might have evolved into birds!

But there are not tens of animals, not hundreds, not thousands, nor millions, but billions!

There are millions of animals, and your local zoo might have a few that can't be seen in the wild!
