Inside your body you have a lot of bones. This is called your skeleton - and you use it to hold your body up (support) and to be able to move around.
Here are some other animals that have skeletons too:
Not all bones are the same! You have lots of different ones, some long, some short. Also, a bird's bones can be very light, while a fish's bones can be quite bendy.
There are loads and loads of animals that don't have bones at all. Can you think of some examples?
In this activity, you can try out your knowledge of bones and skeletons.
