Tortoise
A tortoise is a potentially very long-lived, herbivorous reptile of the order Chelonia. It is closely related to the terrapin and the turtle which are marine and freshwater species of the same order. The tortoise is a common household pet in Great Britain. It hibernates during the cold seasons and is active in summer, generally enjoying gardens with a sunny aspect.
Tortoises have a shell, their most characteristic feature, which is a curved upper carapace adjoined at the sides to a flattened lower pastron. Their front foot is usually a stumpy leg, not a flipper for swimming as may be seen on turtles and terrapins, which also have a flatter carapace. Tortoises can withdraw their head and limbs into the shell for protection. Being herbivorous, the tortoise has not no teeth but it does have a sharp-edged beak and can inflict a nasty bite. Pet tortoises are generally fed on salad items like lettuce or chicory, as well as specially prepared foods to provide vitamins. In the garden, they eat grass and dandelions, among other things.
Perhaps the best known species among small tortoises is the North African (Testudo graeca) which is also native to Asia Minor. The giant tortoise of the Galapagos Islands can be as much as four feet long and weigh over 200 pounds.
Giant tortoises in captivity have been known to live longer than 200 years, and some are believed to have lived 300 years.
