Different types of animal
There are as many as 3 million
different types of animals which
live on earth and in its oceans!
To help quickly work out what
an animal is like, scientists put
them in groups with other
animals that are similar.

Fish
Birds

Reptiles
Insects
Fish
Fish live in water. They use
their tail and fins to swim
around. They can be all sorts of
amazing colours.
Some fish are huge and some

be longer than a bus but some
fish can be smaller than your
fingernail!
