Turtle and Tortoise

Turtles, tortoises, and terrapins are all considered members of the order Testudines (from the Greek word for armor).

These reptiles have populated the planet longer than lizards or crocodiles — going back some 220 million years. They can also lead long lives, with tortoises frequently surviving 100 years or more.
