Turtle Taxonomy Working Group

Last updated

The Turtle Taxonomy Working Group (TTWG) is an informal working group of the IUCN/SSC Tortoise and Freshwater Turtle Specialist Group (TFTSG). [1] It is composed of a number of leading turtle taxonomists, with varying participation by individual participants over the years, some dropping out and others joining.

Works

The TTWG has produced an annual checklist of living and recently extinct turtles since 2007, deliberates on proposed changes to turtle taxonomy, and describes its consideration whether to accept, reject, or suspend adoption of proposed changes in a series of annotations to the checklist. Recent versions of the checklist [2] [3] have included full primary synonymies and citations to all original descriptions of recent turtle taxa, as well as CITES and IUCN Red List status of each species as applicable.

Macrochelys is a genus of very large freshwater turtles in the family Chelydridae from Southeastern United States. Only a single extant species was recognized until a 2014 study divided it into two, or possibly three species.

<span class="mw-page-title-main">Chaco side-necked turtle</span> Species of turtle

The Chaco side-necked turtle or Chaco sideneck turtle is a species of turtle in the family Chelidae. It is found in Argentina, Paraguay, and possibly Bolivia. Its natural habitat is subtropical or tropical moist montane forests. The turtle possesses long horny spurs on its upper thighs. It is 18 cm in shell length. Like other members of its genus, the turtle buries itself in the mud when the streams run dry, a behaviour possibly parallel to the winter hibernating behaviours of turtles further north.

<span class="mw-page-title-main">Bellinger River snapping turtle</span> Species of turtle

The Bellinger River turtle is a species of turtle in the family Chelidae. The species is of moderate size, and is endemic to Australia with a highly restricted distribution to the small coastal drainage of the Bellinger River in New South Wales. In the past the species was considered locally abundant. The species' preferred habitat is the deeper pools of the clear-water upstream reaches of the river, where water flows continuously in most months over a bedrock basement and a stream bed of boulders, pebbles, and gravel. A captive breeding program has been under way since a 2015 virus outbreak came close to wiping out the entire species; most remaining individuals are currently housed in quarantine, though a small number have been reintroduced to the original habitat.

<i>Chelodina burrungandjii</i> Species of turtle

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.
