We have another sample from the Common Dolphin Delphinus delphis specimen. This is the scapula (shoulder blade) of the animal. Compare this to the scapula of the Cougar and the Brown Pelican and see the remarkable variation. Think about how life in different environments (ocean, land, and air respectively) could lead to this variation.
