Some species of tortoises can live years or more. Several common species of pet water turtles can live into their 40s, though there are many factors that will influence how long your pet turtle lives. Your turtle's lifespan depends on its species, its diet and other aspects of its environment that you can control.
They are particularly distinguished from other turtles by being exclusively land-dwelling, while many though not all other turtle species are at least partly aquatic. Like other turtles, tortoises have a shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodirathey retract their necks and heads directly backwards into the shell to protect them. Tortoise can vary in size with some species, Galapagos giant tortoisegrowing to more than 1.
They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. Tortoises are the longest-living land animals in the world, although the longest-living species of tortoise is a matter of debate.
In general, most tortoise species can live 80— years. Differences exist in usage of the common terms turtletortoise, and terrapindepending on the variety of English being used; usage is inconsistent and contradictory. The American Society of Ichthyologists and Herpetologists uses "turtle" to describe all species of the order Testudines, regardless of whether they are land-dwelling or sea-dwelling, and uses "tortoise" as a more specific term for slow-moving terrestrial species.
British usage, by contrast, tends not to use "turtle" as a generic term for all members of the order, and also applies the term "tortoises" broadly to all land-dwelling members of the order Testudines, regardless of whether they are actually members of the family Testudinidae. Australian usage is different from both American and British usage. Most species of tortoises lay small clutch sizes, seldom exceeding 20 eggs, and many species have clutch sizes of only 1—2 eggs.
Incubation is characteristically long in most species, the average incubation period are between and Egg-laying typically occurs at night, after which the mother tortoise covers her clutch with sand, soil, and organic material.
The eggs are left unattended, and depending on the species, take from 60 to days to incubate. The plastron of a female tortoise often has a noticeable V-shaped notch below the tail which facilitates passing the eggs. Upon completion of the incubation period, a fully formed hatchling uses an egg tooth to break out of its shell.
It digs to the surface of the nest and begins a life of survival on its own. They are hatched with an embryonic egg sac which serves as a source of nutrition for the first three to seven days until they have the strength and mobility to find food. Juvenile tortoises often what was the 332nd fighter group known as a different balance of nutrients than adults, so may eat foods which a more mature tortoise would not.
For example, the young of a strictly herbivorous species commonly will consume worms or insect larvae for additional protein. The number of concentric rings on the carapace, much like the cross-section of a how do i stop junk email on my ipadcan sometimes give a clue to how old the animal is, but, since the growth depends highly on the accessibility of food and water, a tortoise that has access to plenty of forage or is regularly fed by its owner with no seasonal variation will have no noticeable rings.
Moreover, some tortoises grow more than one ring per season, and in how to resize a layer in photoshop cc others, due to wear, some rings are no longer visible.
Tortoises generally have one of the longest lifespans of any animal, and some individuals are known to have lived longer than years. The oldest tortoise ever recorded, and one of the oldest individual animals ever recorded, was Tu'i Malilawhich was presented to the Tongan royal family by the British explorer James Cook shortly after its birth in Tu'i Malila remained in the care of the Tongan royal family until its death by natural causes on May 19,at the age of The Alipore Zoo in India was the home to Adwaitawhich zoo officials claimed was the oldest living animal until its death on March 23, Adwaita also spelled Addwaita was an Aldabra giant tortoise brought to India by Lord Wellesley, who handed it over to the Alipur Zoological Gardens in when the zoo was set up.

Jonathana Seychelles giant tortoise living on the island of St Helenamay be as old as years  or years. Many species of tortoises are sexually dimorphicthough the differences between males and females vary from species to species. The male plastron is curved inwards to aid reproduction. The easiest way to determine the sex of a tortoise is to look at the tail.
The females, as a general rule, have smaller tails, dropped down, whereas the males have much longer tails which are usually pulled up and to the side of the rear shell. The brain of a tortoise is extremely small. Red-footed tortoises, from Central and South America, do not have an area in the brain called the hippocampuswhich relates to emotion, learning, memory and spatial navigation.
Studies have shown that red-footed tortoises may rely on an area of the brain called the medial cortex for emotional actions, an area that humans use for actions such as decision making.
In the 17th century, Francesco Redi performed an experiment that involved removing the brain of a land tortoise, which then proceeded to live six months.
Freshwater tortoises, when subjected to the same experiment, continued similarly, but did not live so long. Redi also cut the head off a tortoise entirely, and it lived for 23 days. They are absent from Australasia. They live in diverse habitats, including deserts, arid grasslands, and scrub to wet evergreen forests, and from sea level to mountains.
Most species, however, occupy semiarid habitats. Many large islands are or were characterized by species of giant tortoises. Part of the reason for this is that tortoises are very good at oceanic dispersal.
Despite being unable to swim, tortoises are able to survive long periods adrift at sea because they can survive months without food or fresh water. Tortoises have been known to survive oceanic dispersals of more than km. However, until very recently giant tortoises could be found on nearly every how to get free z tokens in adventure quest island group, including the Bahamasthe Greater Antilles including Cuba and Hispaniolathe Lesser Antillesthe Canary IslandsMaltathe Seychellesthe Mascarene Islands including Maurititus and Reunionand Madagascar.

Many of these giant tortoises are not closely related belonging to different genera such as MegalochelysChelonoidisCentrochelysAldabrachelysCylindraspisand Hesperotestudobut are thought to have how to beat level 225 on candy crush evolved large body size through convergent evolution.
Giant tortoises are notably absent from Australasia and many south Pacific islands, but the distantly related meiolaniid turtles are thought to have filled the same niche. Giant tortoises are also known from the Oligocene - Pliocene of mainland North AmericaSouth AmericaEuropeAsiaand Africabut are all now extinct, which is also attributed to human activity. Most land-based tortoises are herbivoresfeeding on grasses, weeds, leafy greens, flowers, and some fruits, although some omnivorous species are in this family.
Pet tortoises typically require diets based on wild grasses, weeds, leafy greens and certain flowers. Certain species consume worms or insects and carrion in their normal habitats. Too much protein is detrimental in herbivorous species, and has been associated with shell deformities and other medical problems. Different tortoise species vary greatly in their nutritional requirements.
Communication in tortoises is different from many other reptiles. Because they are restricted by their shell and short limbs, visual communication is not a strong form of communication in tortoises. Tortoises use olfactory cues to determine the sex of other tortoises so that they can find a potential mate.
Tactile communication is very important in tortoises during combat and courtship. In both combat and courtship, tortoises use ramming to communicate with other individuals.

Regular vet visits can ensure that your tortoise is always healthy and that you are providing the tortoise with the needed care. A healthy diet is essential to the well being of the tortoise. Many captive-bred tortoises never attain their maximum lifespans because they are not properly fed. First of all, it is important to research and find out the best foods for your tortoise.
You cannot rely solely on commercially made tortoise foods. These should be used to supplement a diet of grasses and other foods high in fiber. Vitamin D3, vitamin A, and calcium deficiency leads to several health complications.
Feeding your tortoise with foods high in calcium such as kale, spinach, and collard greens help ensure that they do not lack this essential nutrient. While different species require different foods, all tortoises require foods high in fiber such as bermudagrass, rye, and alfalfa. Other foods to feed them include dandelions, opuntia cactus, mulberry leaves, clover, timothy hay, and many more. Keeping a clean and large enclosure is essential if you want your turtle to live a long and healthy life.
You can either go with a tortoise table or a fenced outdoor enclosure. For large tortoises such as the sulcata tortoise, you have no choice but to house it outdoors. Small tortoises such as the Egyptian tortoise can be housed in a tortoise table.
Low humidity can lead to all types of life-threatening health complications such as shell pyramiding. Even for tortoises native to arid and semi-arid regions, keep humidity levels between 65 to 70 percent. For tortoises housed indoors, you need to install a UVB light that needs to be changed every 6 months.
