mastermindnews- New Reptile of the day. Land Tortoise

Tortoises (Testudinidae) or land turtles are a family of land-dwelling reptiles of the order of turtles (Testudines). Like their marine cousins, the sea turtles, tortoises are shielded from predators by a shell. The top part of the shell is the carapace, the underside is the plastron, and the two are connected by the bridge. The tortoise has both an endoskeleton and an exoskeleton. Tortoises can vary in size from a few centimeters to two meters. Tortoises are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals.

Although the word "tortoise" is used by biologists in reference to the family Testudinidae only, in common usage it is used to describe many land-dwelling turtles. The inclusiveness of the term depends on the variety of English being used. British English normally describes these reptiles as "tortoises" if they live on land. American English tends to use the word "tortoise" for land-dwelling species, including members of Testudinidae, as well as other species such as box tortoises, though use of "turtle" by default is as common. Australian English uses "tortoise" for terrestrial species, including semi-aquatic species that live near ponds and streams. Traditionally a "tortoise" has feet (including webbed feet) while a "turtle" has flippers.

Giant tortoises move very slowly on dry land, at only 0.17 miles per hour (0.27 km/h)

Most land based tortoises are herbivores, feeding on grazing grasses, weeds, leafy greens, flowers, and some fruits although there are some omnivorous species in this family. Pet tortoises typically require a diet based on wild grasses, weeds and certain flowers. Certain species consume worms or insects and carrion in their normal habitat. Too much protein is detrimental in herbiverous species and has been associated with shell deformities and other medical problems. Cat or dog foods should not be fed to tortoises, as these do not contain the proper balance of nutrients for a reptile. Additionally, it should not be assumed that all captive tortoises can be fed on the same diet. As different tortoise species vary greatly in their nutritional requirements it is essential to thoroughly research the dietary needs of your individual tortoise. The best approach to determining the proper diet is to consult a qualified veterinarian specialising in chelonian care.
