Have you ever wondered what we would look like if we didn't have any bones? It wouldn't be pretty.

Luckily, we don't have that problem. We're vertebrates, animals with bones. Our bones hold us up.

Vertebrates come in different shapes and sizes, but we have many of the same bones. All vertebrates have skill and ribs. And we all have vertebrae. Vertebrae stack up one on top of another to make the spine, or backbone.

Can you imagine how you'd look if we added some bones to your spine? What if your vertebrae didn't stop at your rear end? What if they kept going?

YOU'D HAVE A TAIL! Tails are made of vertebrae. Lots of animals have tails. They wag on happy dogs and sweep side to side to help alligators swim through the water.
