The Geoemydidae are one of the largest and most diverse families in the order Testudines (turtles), with about 70 species. The family includes the Eurasian pond and river turtles and Neotropical wood turtles.
Siebenrockiella leytensis is a species of freshwater turtle endemic to the Philippines. It is classified as critically endangered. It is known as the Philippine forest turtle, the Philippine pond turtle, the Palawan turtle, or the Leyte pond turtle. Despite the latter common name, it does not occur in the island of Leyte but is instead native to the Palawan island group. It is locally known as bakoko in Cuyonon.
The Indian star tortoise is a threatened tortoise species native to India, Pakistan and Sri Lanka where it inhabits dry areas and scrub forest. It has been listed as Vulnerable on the IUCN Red List since 2016, as the population is thought to comprise more than 10,000 individuals, but with a declining trend. It is threatened by habitat loss and poaching for the illegal wildlife trade. It was upgraded to CITES Appendix I in 2019 by full consensus among all member states, giving it the highest level of international protection from commercial trade. Conservation group TRAFFIC found 6,040 were seized globally that were intended to be sold in the pet trade. Currently they are commonly bred in many countries to be sold as pets.
The elongated tortoise is a species of tortoise found in Southeast Asia and parts of South Asia.
The Indian flapshell turtle is a freshwater species of turtle found in South Asia. The "flap-shelled" name stems from the presence of femoral flaps located on the plastron. These flaps of skin cover the limbs when they retract into the shell. It is unclear what protection the flaps offer against predators. Indian flapshell turtles are widespread and common in the South Asian provinces. It is morphologically an evolutionary link between the softshell and hardshell aquatic turtles. Exploitation for profit and habitat change are threats to their survival.
The black pond turtle, also known commonly as the spotted pond turtle and the Indian spotted turtle, is a species of freshwater turtle in the family Geoemydidae. The species, which is endemic to South Asia, belongs to the monotypic genus Geoclemys.
The Cochin forest cane turtle, also known as Kavalai forest turtle, forest cane turtle or simply cane turtle, is a rare turtle from the Western Ghats of India. Described in 1912, its type locality is given as "Near Kavalai in the Cochin State Forests, inhabiting dense forest, at an elevation of about 1500 feet above sea level". Only two specimens were found at that time, and no scientist saw this turtle for the next 70 years. It was rediscovered in 1982, and since then a number of specimens have been found and some studies have been conducted about its phylogeny and ecology.
The red-crowned roofed turtle or Bengal roof turtle is a species of freshwater turtle endemic to South Asia. It was the type species of its former genus Kachuga. Females can grow to a shell length of 56 cm (22 in) and weigh 25 kilograms (55 lb), but males are considerably smaller. The turtles like to bask in the sun on land. In the breeding season, the heads and necks of male turtles exhibit bright red, yellow and blue coloration. The females excavate nests in which they lay clutches of up to thirty eggs.
The brown roofed turtle is a species of turtle in the family Geoemydidae. The species is endemic to South Asia. Two subspecies are recognized.
The Texas map turtle is a species of emydid turtle endemic to Texas.
The Caspian turtle, also known as the striped-neck terrapin, is a species of turtle in the family Geoemydidae (=Bataguridae). It is found in west Asia, in Iran and central Turkey, northward to the Republic of Georgia and eastward to southwestern Turkmenistan, and in Iraq, Saudi Arabia, and Bahrain.
The big-headed pantanal swamp turtle or pantanal swamp turtle is a species of turtle in the family Chelidae found in Brazil, Bolivia, Argentina, and Paraguay.
The yellow-footed tortoise, also known as the Brazilian giant tortoise, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise. It is found in the Amazon Basin of South America. The species name has often been misspelled as denticulata, an error introduced in the 1980s when Chelonoidis was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017.
Dahl's toad-headed turtle is a medium-sized species of side-necked turtle in the family Chelidae. This critically endangered freshwater turtle is endemic to northern Colombia, where it lives in small pools, streams, and swamps, but aestivates on land.
Vanderhaege's toad-headed turtle is a species of turtle in the family Chelidae. The species is endemic to South America.
The Vietnamese three-striped box turtle or green rice turtle is a species of the Southeast Asian genus Cuora. It is distributed from the extreme southern part of the Chinese Guangxi province southwards to central Vietnam and central Laos. This species reaches up to 30 cm straight carapace length and is thus the largest Cuora species. Due to demand of traditional Chinese medicine, this species is nearly extinct in the wild, but is readily bred on Chinese turtle farms. Extremely high prices are paid for this species in China. It can be distinguished from Cuora trifasciata by its larger size and generally more oval or rounder shell, which is usually also flatter, a white, pink, or orange chin, and head coloration with an orange-brownish-olive dorsal head pattern and less black pigment.
The turtle shell is a shield for the ventral and dorsal parts of turtles, completely enclosing all the vital organs of the turtle and in some cases even the head. It is constructed of modified bony elements such as the ribs, parts of the pelvis and other bones found in most reptiles. The bone of the shell consists of both skeletal and dermal bone, showing that the complete enclosure of the shell likely evolved by including dermal armor into the rib cage.
Cyclemys is a genus of freshwater turtles, commonly referred to as Asian leaf turtles, from the family Geoemydidae. The genus occurs throughout Southeast and South Asia, and currently contains seven species.
Chelodina canni, also known commonly as Cann's snake-necked turtle, is a species of turtle in the family Chelidae. The species is endemic to Australia, where it is found in the northern and northeastern parts of the continent. It has a narrow zone of hybridization with its related species the eastern snake-necked turtle, C. longicollis. For many years C. canni was assumed to be the same species as C. novaeguineae from New Guinea. However, in 2002 it was shown that these two species differ both morphologically and genetically, and therefore C. canni was separated and described as a unique species.
Basilemys is a large, terrestrial nanhsiungchelyid turtle from the Upper Cretaceous of North and Central America. Basilemys has been found in rocks dating to the Campanian and Maastrichtian subdivisions of the Late Cretaceous and is considered to be the largest terrestrial turtle of its time. In an analysis made by Sukhanov et al. on a nansiunghelyid turtle from the Upper Cretaceous of Mongolia, it was demonstrated that Asian nanhsiungchelyids gave rise to the North American nanhsiungchelyids.
