Herbivore: "Box" Turtle			Carnivore: Alligator Snapping Turtle

Turtles rely on their jaw when digesting food, which is aligned with horny ridges in place of teeth. Depending on the eating habits of the turtle, the jaw structure is different. Herbivorous turtles, such as the box turtle, have serrated edged ridges to break down tough plants. Carnivorous turtles, such as the Alligator Snapping Turtle, have knife-sharp ridges to slice up their prey. But unlike most reptiles, turtles cannot use their tongues to catch food

Herbivore: Aldabra Giant Tortoise			Omnivore: Malaclemys Terrapin
