Eagle Anatomy in 3D: Hollow Bones, Lungs and Super Sight
Eagles are birds of prey built for flying and spotting food from far away. Their bones are light and filled with air, and their lungs keep fresh air flowing all the time. In the 3D Animal Anatomy simulator you can turn an eagle around, look inside and see its skeleton.

The eagle skeleton
An eagle's skeleton is strong but very light. Many bones are hollow with air inside, the breastbone has a deep keel where the flight muscles attach, and the feet end in sharp talons for gripping prey.

- Brain
- Large areas for sight help it spot prey from far away.
- Heart
- Pumps blood around the whole body, all day and night.
- Lungs
