Have you ever seen the skeleton of a turtle? Via Biologia-Vida
“The shell of a turtle, composed of carapace (top) and plastron (bottom), is formed by bones and covered by a layer made of the protein keratin (the same substance present in our nails and hair). Contrary to what most people believe, the turtle does not outgrow its shell, because these keratin layers, called scutellum, sheds several times during the year to allow the shell to grow along with the animal. That’s why turtles rub themselves in stone and stay in the sun, to dry the scutellum and facilitate the shed, and warmth, since they are cold blooded animals and cannot maintain constant heat in the body.”
