Do turtles have bodies inside their shells?
Thanks to cartoons, many of us think of the turtle’s shell as more of a housing or case. Rather the shell is part of the turtle’s body and is made of bones, collagen, skin, and keratin. The turtle doesn’t have a separate body within the shell. As such, the shell has nerve endings and can bleed when damaged.
What is the body structure of turtle?
The turtle shell consists of dorsal and ventral parts: the carapace and plastron, respectively. The basic structure of the carapace comprises vertebrae and ribs. The pectoral girdle of turtles sits inside the carapace or the rib cage, in striking contrast to the body plan of other tetrapods.
What is the difference between carapace and plastron?
The key difference between carapace and plastron is that carapace is the dorsal part of the shell while plastron is the ventral part of the shell of an animal, especially a crustacean. Arthropods have an exoskeleton or a shell. Some vertebrates, especially tortoises and turtles, also have an exoskeleton.
