The African softshell turtle, or Nile softshell turtle (Trionyx triunguis), is a large species of softshell turtle from freshwater and brackish-water habitats in Africa (larger parts of Eastern, Northeastern, Western and Middle Africa) and the Near East (Israel, Lebanon, Syria and Turkey). [3] It is the only extant species in the genus Trionyx ; historically, despite other species having been formerly placed in this genus as well, they have all been reclassified to other genera. [3]
Despite the common name of "African softshell turtle", Trionyx triunguis is not the sole species (or genus) of softshell turtle found in Africa—the genera Cyclanorbis and Cycloderma are African—nor is it solely found on that continent, alone. [3]
T. triunguis is a very large species of softshell turtle, with sizes ranging from 85 to 94 cm, with a weight of 40 kg, and an unconfirmed max size of 120 cm. They are omnivorous in their diet, consuming not only small fish, frogs, tadpoles and crustaceans, but also floating palm seeds and fallen leaves, and some aquatic vegetation.
T. triunguis was listed on CITES’s Appendix II in 2016; the population in Ghana was also included in CITES’s Appendix III from 1976 to 2007. The Mediterranean subpopulation of the Nile soft-shelled turtle was listed in the “Red List of Threatened Species” by the IUCN, as critically endangered. They are under threat because of large use of their habitats with fishing activities, and irrigation, destruction of their nesting places, destruction caused by boats, and water pollution.
In Ancient Egyptian religion the African softshell turtle seems to have been viewed as a symbol of evil animal and opponent of Ra. [5]
The Asian giant softshell turtle, also known commonly as Cantor's giant softshell turtle and the frog-faced softshell turtle, is a species of freshwater turtle in the family Trionychidae. The species is native to Southeast Asia. The species is critically endangered and in the 20th century has disappeared from much of its former range.
Leith's softshell turtle is a species of turtle in the family Trionychidae. The species is found in peninsular Indian rivers including the Thungabhadra, Ghataprabha, Bhavani, Godavari, Kaveri and Moyar Rivers. The type locality is Pune in India.
The Indian softshell turtle, or Ganges softshell turtle is a species of softshell turtle found in South Asia in rivers such as the Ganges, Indus and Mahanadi. This vulnerable turtle reaches a carapace length of up to 94 cm (37 in). It feeds mostly on fish, amphibians, carrion and other animal matter, but also takes aquatic plants. This turtle is listed in part II of Schedule I of the Wild Life (Protection) Act, 1972 and possession of this species is an offence.
The wattle-necked softshell turtle, also commonly known as Steindachner's soft-shelled turtle, is an endangered Asian species of softshell turtle in the family Trionychidae. The species is the only member of the genus Palea.
Pelochelys is a genus of very large softshell turtles in the family Trionychidae. They are found from peninsular India northeast to southern China, and south to Southeast Asia and New Guinea.These turtles are also known as Giant softshell turtles.
The Chinese softshell turtle is a species of softshell turtle that is native to mainland China and Taiwan, with records of escapees—some of which have established introduced populations—in a wide range of other Asian countries, as well as Spain, Brazil and Hawaii.
Trionychia is a superfamily of turtles which encompasses the species that are commonly referred to as softshelled turtles as well as some others. The group contains two families, Carettochelyidae, which has only one living species, the pig-nosed turtle native to New Guinea and Northern Australia, and Trionychidae, the softshelled turtles, containing numerous species native to Asia, North America and Africa. These families likely diverged during the late Jurassic. The oldest known stem-trionychian is Sinaspideretes from the Late Jurassic of China.
The Florida softshell turtle is a species of turtle in the family Trionychidae. The species is native to the Southeastern United States.
The Cuatro Ciénegas softshell, also called the black spiny softshell, is a subspecies of the spiny softshell turtle in the family Trionychidae. It is found only in the Cuatro Ciénegas Basin in the Mexican state of Coahuila and it is considered critically endangered by the IUCN. The subspecies, along with its parent species, was formerly classified in the genus Trionyx.
The Nubian flapshell turtle or Nubian soft-shelled turtle is one of two species of softshell turtle in the genus Cyclanorbis of the Trionychidae family. It is thought to have ranged from West Africa east through Central Africa to South Sudan, although it has been extirpated from the vast majority of its range.
The Senegal flapshell turtle is a species of turtle in the subfamily Cyclanorbinae of the family Trionychidae. The species, which is one of two species of softshell turtles in the genus Cyclanorbis, is endemic to Africa.
The Malayan softshell turtle is a species of softshell turtle in the family Trionychidae. It is monotypic in its genus.
Nilssonia is a genus of softshell turtles from rivers, streams, ponds, and lakes in South Asia and Burma. In many treatments, it is monotypic, with the single species Burmese peacock softshell. However, the supposed other genus of peacock softshells, Aspideretes, is more closely related to N. formosa than had been believed. They differ only in the neural plates between the first pleural scale pair of the bony carapace, which are fused into one in N. formosa and unfused in the others.
The southern New Guinea giant softshell turtle is a species of softshell turtle in the family Trionychidae. The species is endemic to the lowlands of southern New Guinea with occasional vagrant individuals sighted off the coast of northern Australia. There is no confirmed Australian record. P. bibroni is referred to by the Suki people as kiya eise, a reference to its flexible shell. In the Arammba language, it is called sokrere, meaning "earthquake". It is sometimes hunted by local villages for its meat and/or eggs, leading to some cases of chelonitoxism.
Rafetus is a genus of highly endangered softshell turtles in the family Trionychidae. It is a genus of large turtles which are found in freshwater habitats in Eurasia.
The Euphrates softshell turtle, also known as the Mesopotamian softshell turtle, is a species of softshell turtle in the family Trionychidae. It is found throughout much of the Euphrates–Tigris river basin in Iraq, Syria, Turkey and Khūzestān Province of Iran. Historically it has also been reported from Iran, but this likely involves confusion with the very similar Trionyx triunguis.
Trionyx is a genus of softshell turtles belonging to the family Trionychidae. In the past many species in the family were classified in this genus, but today T. triunguis, the African or Nile softshell turtle, is the only extant softshell still classified as Trionyx. The other species still assigned to this genus are only known from fossils. T. triunguis is a relatively large, aquatic piscivore.
The Burmese narrow-headed softshell turtle, also known commonly as the Myanmar narrow-headed softshell turtle and Van Dijk's chitra, is a species of turtle in the family Trionychidae. The species is endemic to Southeast Asia.
The northern New Guinea giant softshell turtle is a species of turtle found in the lowlands of northern New Guinea. South of the Central Range it is replaced by the closely related southern New Guinea giant softshell turtle. It is threatened by overhunting and harvesting of eggs as well as significant habitat loss of aquatic vegetation due to introduced fish species such as the red-bellied pacu.
Pelodiscus maackii, commonly known as the Amur softshell turtle or the northern Chinese softshell turtle, is a species of turtle in the family Trionychidae. The species is found in the Russian Far East, northeastern China, Korea, and Japan. It is possible that the Japanese populations are the result of ancient introductions by humans. This aquatic species may attain a straight carapace length of 32.5 cm (1.1 ft).
