Any terrestrial member of the family Testudinidae in the order Chelonia is known as tortoise. Tortoises inhabit temperate and tropical regions. The majority, however, are found in Africa and Madagascar. Their habitats range from dry and hot desert regions to the humid jungles. They are characterized by having usually rigidly ossified and high domed shells and hard-scaled forelegs. The head and neck are completely retractile. The hind limbs are club and column shaped. Feet are armed with horny claws. Some tortoises have partly ossified strong scales on the outside of both fore and hind legs. Tortoises are very slow moving animals and are able to breed at about six years of age.
