Amazing Facts About Animals: Introduction

On this page we're going to take a look at some of the planet's most amazing animals!

The animal kingdom is one of five kingdoms of living things (or six in the US, where microscopic species are classified slightly differently).

A ‘Kingdom’ is a category that we use to classify living things, so that we can understand them better.

Another example of a kingdom is the Plant kingdom.

Animals can be split into two main groups: vertebrates (animals with backbones) and invertebrates (animals without backbones).

Only 5% of the world’s animals are vertebrates. The other 95% are invertebrates such as insects, crustaceans (animals like crabs and lobsters) and molluscs (animals like snails and octopuses).

Around half of the world’s vertebrates are fishes.

Around 75% of the world’s invertebrates are insects.

On this page we're going to look at some of the most amazing members of the animal kingdom.
