Originally developed to aid in sand digging, the turtle shell has gradually evolved into a protective shield for turtles against weather and predators.
| The turtle shell is a complex structure that protects the belly and back of various turtle species, completely enveloping all of the turtle’s vital organs, and in some cases, even its head. The turtle shell is formed from modified vertebrae, ribs, and pelvic bones, which have evolved into a bony cage enveloped by a layer of skin that protrudes outward. The turtle shell is considered an extraordinary marvel of evolution and is a defining characteristic of turtles. |
