The Southeast Asian softshell turtle (Amyda ornata) is a species of softshell turtle in the family Trionychidae. [2]

Taxonomy

It was formerly considered a subspecies of the Asiatic softshell turtle (A. cartilaginea), which is now thought to be restricted to the Malay Peninsula and the Malay Archipelago. A 2014 phylogenetic study found both to be distinct species from one another. [3] The Reptile Database and Turtle Taxonomy Working Group also consider both to be distinct species. [2]

There are two subspecies:

An undescribed subspecies is also known from Bangladesh, though the TTWG classifies it within A. o. phayrei. [2] [3]

Distribution

The species is found throughout much of Mainland Southeast Asia, and ranges from northwestern India south to southern Myanmar and east to Vietnam. [2]

Description

Compared to A. cartilaginea, A. ornata is of an "arrow headed form" and has a "lighter base color and a more diffuse yellow spotting, which is 'usually restricted to the cheeks, there are no ocelli but black dots may be present on the carapace, the nuchal tubercles are always weakly developed and the animals always show three (or rarely two) converging black lines on the head'". Along with Amyda ornata subspecies (unnamed) from Bangladesh and Amyda ornata phayrei, Amyda ornata ornata's "morphology matches the turtles studied by Kuchling et al. 2004". In addition, Amyda ornata subspecies (unnamed) has "a rather uniform pale color and very large tubercles in the nuchal and back region of the carapace". [3] [4]

Status

The IUCN Red List presently groups A. ornata with A. cartilaginea, and has found them to be Vulnerable due to overexploitation for consumption. A provisional assessment of A. ornata as a distinct species has also found it to qualify for a Vulnerable status. [2]

Trionychidae Family of turtles

The Trionychidae are a taxonomic family of a number of turtle genera, commonly known as softshell turtles. The family was erected by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish areas. Members of this family occur in Africa, Asia, and North America, with extinct species known from Australia. Most species have traditionally been included in the genus Trionyx, but the vast majority have since been moved to other genera. Among these are the North American Apalone softshells that were placed in Trionyx until 1987.

Arakan forest turtle Species of turtle

The Arakan forest turtle is a critically endangered turtle species native to the Arakan Hills in western Myanmar and the bordering Chittagong Hill Tracts in Bangladesh. The Arakan forest turtle is a semiterrestrial turtle, meaning it can survive in aquatic as well as terrestrial habitats, but adults prefer living in terrestrial habitats.

Indian narrow-headed softshell turtle Species of turtle

Indian narrow-headed softshell turtle also known as small-headed softshell turtle is an endangered species of softshell turtle found in rivers of the Indian subcontinent.

Indian softshell turtle Species of turtle

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.

Spiny softshell turtle Species of turtle

The spiny softshell turtle is a species of softshell turtle, one of the largest freshwater turtle species in North America.

<i>Amyda</i> Genus of turtles

Amyda is a genus of softshell turtles in the family Trionychidae. It contains two extant species:

<i>Nilssonia</i> (turtle) Genus of turtles

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.

Smooth softshell turtle Species of turtle

The smooth softshell turtle is a species of softshell turtle of the family Trionychidae. The species is endemic to North America.

<i>Pelodiscus</i> Genus of turtles

Pelodiscus is a genus of turtles in the family Trionychidae, the softshells. Based on genetic and morphological analysis there are six valid species. They are native to Eastern Asia, ranging from the Amur region, south through China and Korea, as far south as Vietnam. Populations in Japan are thought to likely originate from historic human introductions.

Amur softshell turtle Species of turtle

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).
