Detailed explanation-1: -Turtle shells, made of bones fused with their ribs, obviously protect vital organs against predators. But the protective ability of the turtle’s skull-far greater than other animals’-was a surprise that has triggered scientists to take a closer look at the skull’s architecture and engineering.
Detailed explanation-2: -The ventrum of turtles is covered by a protective shell, the plastron, composed of bony plates that are themselves covered by keratinous scutes.
Detailed explanation-3: -The turtle shell is actually a peculiar evolution of a turtle’s bone structure. Its vertebrae, pelvis, ribcage–it has no muscles between its ribs, which makes this easier–and other bones fuse together to form a sort of reptilian exoskeleton.
