Is the shell part of the turtle?

A turtle can't crawl out of its shell, just like we can't crawl out of our own skeletons. In fact, the shell is actually part of a turtle's skeleton, comprised of the ribcage, vertebrae, and sternum. But if you could peer inside a turtle shell, you'd find some of the most unusual features in the animal kingdom.

What is shell of the turtle?

A turtle's shell is as much a part of its body as our skeleton is to ours. The shell is made of two pieces, the carapace (top) and the plastron (bottom), which are fused together on each side at what's called a bridge. The carapace is covered by an outer layer of individual pieces called scoots.
