Animals come in a huge variety of colours, shapes and sizes!
These differences are for very special reasons. Animals have evolved to adapt to their habitat. Think of an animal - any animal! Every organism is adapted to live in its habitat - it's designed for where it lives. This means that it will be able to grow and reproduce.
Some animals are adapted to live in water, like the sea lion.
Some animals have adaptations which allow them to eat food that others cannot reach, like the humming bird, which drinks nectar from the middle of flowers.
Some animals have evolved colours and patterns that allow them to blend into their habitat, like the giant panda which blends into shaded bamboo forests.
