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.
Every organism is adapted to live in its habitat - it's designed for where it lives. This means that it will be able to feed, grow and reproduce.
Some animals are adapted to live in water, like the sea lion - it has a streamlined body and flippers to help it swim fast.
Some animals have adaptations which allow them to eat food that others cannot reach, like the hummingbird, which drinks nectar from the middle of flowers - its wings beat so fast it can hover in front of a flower, and even fly backwards! Its long beak helps it to reach into the flower for the nectar.
Some animals have evolved colours and patterns that allow them to blend into their habitat. The giant panda's black and white colouring blends into shaded bamboo forests and helps to camouflage it in China's snowy winters.
Right, let's have a look at how organisms are adapted to their habitats.
