Tortoise for sale, are members of the order Testudines and family Testudinidae of reptiles. Tortoises, like other turtles, have a shell to protect them from predators and other dangers. Since tortoises often have hard shells, they protect themselves by straightening their heads and necks into the shell, like other members of the suborder Cryptodira.
While certain species of tortoises, like the Galápagos giant tortoise, can reach lengths of more than 1.2 meters (3.9 feet), others, like the Speckled cape tortoise, have shells that are only 6.8 centimeters (2.7 inches) long.Several lineages of tortoises, such as the Galapagos giant tortoise and the Aldabra giant tortoise, have independently attained extraordinarily enormous body sizes weighing more than 100 kg.
They are mostly nocturnal animals with a tendency to become crepuscular as the temperature changes. They are often solitary creatures. The longest-living species of tortoise is up for debate, however they are the world’s longest-living terrestrial animals. Although it is known that Galápagos tortoises can live for more than 150 years, Adwaita, an Aldabra giant tortoise, is thought to have lived for an estimated 255 years.
