Bones : skeletons and how they work
(Book)

Bones come in all shapes and sizes. They grow. They support. They can even repair themselves when they break. Steve Jenkins explores the differences between human and animal bones, many of them shown at actual size. Take a close look at a human hand and those of a spider monkey, a mole and a bat. Compare the great weight of an elephant's leg with the feather-light femur of a stork.
