"Phylogenetic relationships of chelid turtles (Pleurodira: Chelidae) based on mitochondrial 12S rRNA gene sequence variation". [15] The subfamilies within Chelidae show the monophyly of the majority of the South American species and all the Australian species, with the far more ancient Hydromedusa as sister taxon to both these other groups. Like all pleurodirous turtles, the chelids withdraw their necks sideways into their shells, differing from cryptodires that fold their necks in the vertical plane. Thomson S. (2003). Cann, J. Chelidae is one of three living families of the turtle/tortoise suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. – Intergular scute contacts and partly separates the pectoral scutes Pseudemydura, 3 Suture between the second and third costal scutes contacting the seventh marginal scute; suture between the third and fourth costal scutes contacting the ninth marginal scute 4 These turtles got their common name because they're unable to tuck their heads entirely inside their shells, so they tuck them to the side instead. The physical differences between them, although anatomical and largely internal, are nonetheless significant, and the zoogeographic implications of them are substantial. "Resolving the phylogenetic history of the short-necked turtles, genera. Individuals can grow to 4740.97 g. William’s South American Side Necked Turtle has sexual reproduction.

Chelodina, 2 Intergular scute not in contact with the pectoral scutes 3 The Chelidae are one of three living families of the turtle suborder Pleurodira and are commonly called the Austro-South American side-neck turtles. [10] This was accepted for some time, but brought into scrutiny,[11] because the major differences between the genera showed they all appeared to have evolved independently of each other, hinging on the fact that although they had long necks, how they used them and their structures were different. Seddon, J.; Georges, A.; Baverstock, P. & McCord, W. (1997). The extra scute is called the intergular.

Using shared derived characters, an early attempt in the 1970s used strict parsimony to determine the three long-necked genera (Chelodina, Chelus, and Hydromedusa) were each other's closest relatives. The group of side-necked turtles that lives in Africa. The family contains 37 species in nine genera. Baur, Georg. Aquatic turtles are fun to watch, especially when they're as unique looking as the African sideneck turtle. The Pleurodira are known more commonly as the side-necked turtles and the name Pleurodira quite literally translates to side neck, whereas the Cryptodira are known as hidden-necked turtles. The Family is distributed in Australia, New Guinea, parts of Indonesia and throughout most of South America. Afro-American Side-necked Turtles. The family contains 37 species in nine genera.
