Tortoises are reptiles of the family Testudinidae of the order Testudines. 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 Cryptodira, they retract their necks and heads directly backward into the shell to protect them.
The Texas tortoise is a species of tortoise in the family Testudinidae. The species G. berlandieri is one of six species of tortoises that are native to North America.
Chelodina, collectively known as snake-necked turtles, is a large and diverse genus of long-necked chelid turtles with a complicated nomenclatural history. Although in the past, Macrochelodina and Macrodiremys have been considered separate genera and prior to that all the same, they are now considered subgenera of the Chelodina, further Macrochelodina and Macrodiremys are now known to apply to the same species, hence Chelydera is used for the northern snake-necked turtles.
Oldham's leaf turtle is a species of turtle in the family Geoemydidae.
Gopherus is a genus of fossorial tortoises commonly referred to as gopher tortoises. The gopher tortoise is grouped with land tortoises that originated 60 million years ago, in North America. A genetic study has shown that their closest relatives are in the Asian genus Manouria. The gopher tortoises live in the southern United States from California's Mojave Desert across to Florida, and in parts of northern Mexico. Gopher tortoises are so named because of some species' habit of digging large, deep burrows. Most notably, Gopherus polyphemus digs burrows which can be up to 40 feet (12 m) in length and 10 feet (3.0 m) in depth. These burrows are used by a variety of other species, including mammals, other reptiles, amphibians, and birds. Gopher tortoises are 20–50 cm (7.9–19.7 in) in length, depending on the species. All six species are found in xeric habitats. Numerous extinct species are known, the oldest dating to the Priabonian stage of the Late Eocene of the United States.
The Roti Island snake-necked turtle, also commonly known as McCord's snakeneck turtle, is a critically endangered turtle species. It is named after Rote Island in Indonesia where it was first discovered. Some individuals were later discovered in East Timor, and are considered a distinct subspecies.
Chelonian Conservation and Biology: International Journal of Turtle and Tortoise Research is a peer-reviewed scientific journal covering research on freshwater turtles, marine turtles, and tortoises. It was established in 1993 by the Chelonian Research Foundation as the new scientific journal of the IUCN Species Survival Commission's Tortoise and Freshwater Turtle Specialist Group and the International Bulletin of Chelonian Research. The journal was first published with support from Conservation International, the Chelonian Institute, the Wildlife Conservation Society, the Florida Audubon Society, and the Species Survival Commission of the World Conservation Union.
Elseya is a genus of large side-necked turtles, commonly known as Australian snapping turtles, in the family Chelidae. Species in the genus Elseya are found in river systems in northern and northeastern Australia and throughout the river systems of New Guinea. They are identified by the presence of alveolar ridges on the triturating surfaces of the mouth and the presence of a complex bridge strut.
The Western New Guinea stream turtle or New Guinea snapping turtle is a species of freshwater turtle in the Chelidae family. It is found in the Bird's Head Peninsula and the Bomberai Peninsula west of Cenderawasih Bay, and on the island of Waigeo of West Papua, Indonesia.
The variable mud turtle, also known as Rhodesian mud turtle, Mashona hinged terrapin or variable hinged terrapin, is a species of turtle in the family Pelomedusidae. It is widely distributed in Central, East, and Southern Africa. The species was officially described by John Hewitt in 1927 and had to be broken into subspecies due to color variations on the heads of the turtles acrost the regions.
Elseya albagula, commonly known as the white-throated snapping turtle, is one of the largest species of chelid turtles in the world, growing to about 45 cm (18 in) carapace length.

Chelodina (Chelydera) burrungandjii, the sandstone snake-necked turtle or Arnhem Land long-necked turtle, is a medium-sized turtle reaching carapace lengths of 316 mm. The species is found in the sandstone plateaus and escarpments and the plunge pools of Arnhem Land of the Northern Territory. The species had been long recognised as valid. However, it had been difficult to research due to the remoteness of its habitat. Efforts to breed this species in captivity had been largely unsuccessful, until National Aquarium Herpetologist Matthew Benedict lead a successful breeding project in 2021. The species occurs in proximity to Chelodina rugosa, to which it is closely related. For the most part the two species are parapatric in distribution. However, they do come together in limited locations such as plunge pools at the base of the escarpments. In these areas there is hybridization between the species.
The African dwarf mud turtle is a species of turtle in the family Pelomedusidae. It is endemic to Africa : in Angola, the Democratic Republic of the Congo, Malawi, and Zambia. These mud turtles are the smallest of all African turtle species, “Nanus” which they are referred to are one of the 3 smallest turtle species in the world. The other two are Stink Pot Musk and Muhlenberg's Bog Turtles. All 3 species barely reach 4 inches as full grown adults. Like many of the world's chelonians, Pelusios castaneus has the potential to live a long life. Reports typically suggest more than 50 years in captivity for this species.
Elseya schultzei, commonly known as Schultze's snapping turtle, is a species of chelid turtle endemic to northern New Guinea.
Chelodina (Chelydera) kuchlingi, commonly known as Kuchling's long-necked turtle or Kuchling's turtle, is a species of freshwater turtle in the family Chelidae. The species is endemic to Australia.
The Mapimí Biosphere Reserve is a UNESCO Biosphere Reserve located in the state of Durango in northern Mexico. It is one of three biosphere reserves representing the Chihuahuan Desert. The 342,388 hectares (1,321.97 sq mi) reserve is situated between the Neotropical and Nearctic biogeographic realms, in the Bolsón de Mapimí 1,150 metres (3,770 ft) above sea level. It contains three core areas in the Sierra de la Campana, the Laguna de las Palomas, a salt lagoon, and a desert habitat called Dunas de la Soledad. It comprises fragile warm desert and semi-desert ecosystems and rich, highly adapted but vulnerable plant systems, mainly xerophytic matorral scrub, and animal species such as the puma, mule deer, sandhill crane and the kit fox or zorrita del desiert along with scrub and desert grasslands.
The Sonoran Desert tortoise, or Morafka's desert tortoise, is a species of terrestrial chelonian reptile of the family Testudinidae (tortoises) native to the Sonoran Desert.
The Goode's thornscrub tortoise, also known as the Sinaloan thornscrub tortoise, Sinaloan desert tortoise or Goode's desert tortoise, is a species of tortoise that is native to the Sinaloan desert region. First described in 2016, G. evgoodei inhabits Tropical Deciduous Forest and Sinaloan Desertscrub biomes in Mexico. Its range may overlap in the north with G. morafkai, the Morafka's or Sonoran desert tortoise.
