Three Toed Box Turtle

Terrapene carolina triunguis
Back to Animals â†’

Three-toed box turtles earned their name for the three toes on their back feet. They are typically an olive-brown color with occasional yellow markings. The three-toed box turtle is one of six subspecies of box turtle, and it’s one of the few species that can pull all their limbs into their shell, completely sealing themselves shut. They’ll use this defensive technique, when frightened or threatened, making it impossible for anything to reach them.

Their shell is made up of 60 bones, and if you look closely, you can see their spine along the middle of it. Three-toed box turtles’ shells are comprised of bone (bottom layers) and keratin (upper layers). Their shells are a fusion of the turtles’ ribs and spine, so they are permanently attached.

Three-toed box turtles can be found in south-central United States, and they’re recognized as the state reptile in Missouri!
