Glass Frog

Special | 6m 26s

The glass frog is called so because it has see-through skin on its stomach! How crazy is that? You can see just about all of its inner organs, including its beating heart. The glass armonica on the other hand is one of the rarest and most exotic musical instruments, and it was invented by Benjamin Franklin!
