Skeletons of Animals and Birds

Some animals have a backbone. Some do not.

Animals with backbones are called vertebrates - backboned animals.

Backboned animals have a hard body frame inside them - their skeleton.

Fish, amphibians, reptiles, birds and mammals have a skeleton.

You are a mammal. You have a bony skeleton. Your skeleton grows with you.

Try Build a Skeleton and see if you can find some similarities between the different skeleton types.

Drawing of a bird Skeleton
Birds have lightweight bones, many of which are hollow. For added strength, the hollow bones are supported by internal struts (much like the struts that support the hollow wings of planes).If bird bones were solid, like human bones, birds would be too heavy, which would make flight very difficult.
