A turtle shell is not separate armor but evolved ribs and spine fused into bone plates covered by keratin shields. Shell and body grow together and cannot be removed. Turtles retract into this bony shield for protection. The shell is part of the turtle's skeleton. Kids love spotting this when visiting a zoo or watching nature shows with family.
