Can you imagine what the world would look like if you were a cat, or an elephant, or even an astronaut in outer space? If you have played the Animal Sight game, you know already that some animals see the world in a very different way to us. Some animals can only see dark and light - they wouldn't even be able to tell if a traffic light was red or green, although they shouldn't really be driving a car at all!

So, why do animals see differently?
The answer is often to do with where the animal lives and how it gets its food.

The cat has really good eyesight and can see much better than we can in the dark. This is good for hunting at night, but humans have better daylight vision than cats. Why do you think that is?

The eyesight of bats is very different to humans. You may have heard the saying 'blind as a bat'. Well, this isn't quite true as no bats are actually blind, and some can see even better than humans can in dim lighting. Bats use sight, smell and hearing to find their food, and some use sound waves to find out how far away objects are from them.

The eyes of birds are large and they can see really clearly. This is so that they are more able to find food like worms, or see danger, like animals trying to catch them (usually the cat in my garden!)

An elephant's eyesight is really poor - think about how small their eyes are for such a large animal. But elephants do have a good sense of smell, hearing, taste and touch which makes up for this.

Some animals are able to see all around them. They tend to be animals that hunt for their prey, so need to be on guard in case there's a meal around. If they didn't have this sort of vision they'd probably go hungry!

Think about where an animal lives and what it eats, if another animal hunts it, or if it does the hunting. This usually affects the way they see the world.
