Carettochelys insculpta is the sole living member of the Carettochelyidae, a group whose stratigraphic range extends as far back as the Mesozoic (Cretaceous of central Asia).
Cladistic analyses of both morphological and molecular characters place the Carettochelyidae as a close relative to the soft-shelled turtles of the Trionychidae (Meylan, 1987; Meylan and Gaffney, 1989; Shaffer et al., 1997).
Meylan, P. Peltochelys Dollo and the relationships among the genera of the Carettochelyidae (Testudines: Reptilia).
The purpose of this paper is to explain all husbandry requirements of Carettochelys insculpta and thus help decrease the number of specimens that prematurely pass away.
It was originally described as a Pleurodire (Ramsay, 1886) and proposed to be a link between the freshwater turtles and the sea turtles (Ramsay, 1886).
The genus was assigned to a new family Carettochelyidae (Boulenger, 1887) and it was Baur (1891) who moved Carettochelys, and its family Carettochelyidae, to the Cryptodires and pointed out the similarity to the Trionychia.

The Australasian Pig-Nose Turtle also know as the '''Pitted-shelled Turtle''' is the single species in the genus ''Carettochelys'' and the family Carettochelyidae.
It is only found in freshwater streams and rivers of the Northern Territory of Australia and of southern New Guinea.
The close relationship of mud turtles (Kinosternidae) and the monotypic family Dermatemydidae, as the Kinosternoidae, is supported as is the close relationships between softshells (Trionychidae) and the Fly River or Pignosed Turtle (Carettochelyidae) as the Trionychoidae.
On major conflict between the molecular evidence and previous morphological studies is the purported monophyly of the large superfamily Trionychoidea (Trionychidae, Carettochelyidae, Kinosternidae and Dermatemydidae).
Bootstrap analysis of the morphological data set demonstrates moderate support based on morphological characters, but it is not supported by the molecular data.
Pattern I, found in some Bataguridae, and the Carettochelyidae, Cheloniidae, Dermochelyidae, Emydidae, and Testudinidae, has a single transition zone of temperature below which incubation yields nearly or totally 100% males and above which only females are produced.
Pattern I occurs chiefly in turtles in which the adult females are larger than adult males; Pattern II is found mainly in turtles with females smaller than males or in which body size is not dimorphic.

(N.B. The family Carettochelyidae is currently known to contain only the species Carettochelys insculpta.)
Unlike a number of other Asian freshwater turtle species, Carettochelys insculpta is both consumed for food in large quantities and traded for use as pets.
The Centre of Excellence in Cleaner Production has been established with support from the Waste Management and Recycling Fund at Curtin University of Technology, to promote the uptake of cleaner production and waste minimisation activities in Western Australia.
Very detailed site, dedicated to the Chelidae and Carettochelyidae families of freshwater turtles.
The ARC is a centre dedicated to research and conservation of Australia's unique frogs.
Turtles of the families Carettochelyidae, Dermochelyidae, and Trionychidae have lost the horny covering of scutes, and the bony material in their shells is much reduced.
These turtles are often referred to as leatherbacks or softshells.
Volume two covers all the other species, counts 265 pages and 200 color fotographs.
This is the second part,covering the species Kinosternidea, platysternidae, testudinidae, trionychidae, carettochelyidae, cheloniidae, dermochelidae, chelidae, pelomedusidae.

Adopt: “The available information suggests that harvesting from the wild for international trade is having a detrimental impact on species of the family Carettochelyidae Â…trade should be regulated to avoid utilization that is incompatible with the long-term survival of the species.”
