As members of the Chelonian reptile family, turtles, tortoises and terrapins are related. The difference between tortoises and turtles is that tortoises are herbivores that live on land while turtles are omnivores that live in the sea. Terrapins are one type of small turtle that lives in brackish water.
Tortoise Fun Facts
All tortoises start out as these tiny, cute little tanks. Many can easily fit in the palm of your hand. Eventually, though, they can grow to be hulking, heavy, lumbering creatures. This, of course, varies on the species of tortoise that you get, where it came from in the world, and its health as it grows.
