''Acanthochelys'' is a genus of turtles, the spiny swamp turtles, in the family Chelidae, subfamily Chelinae, found in South America. Until recently, the species of this genus were considered to be members of the genus ''Platemys'', but were moved to the resurrected genus originally described by Gray (1873) based on the type species by monotypy ''Acanthochelys spixii''.Iverson, J.

Acanthochelys Macrocephala
The big-headed pantanal swamp turtle or pantanal swamp turtle (''Acanthochelys macrocephala'') is a species of turtle in the family Chelidae found in Brazil, Bolivia, Argentina, and Paraguay. Recognition This is the largest of the South American ''Acanthochelys'' species, growing to in carapace length. It has a broad, oval to moderately elongated, deep carapace with a shallow dorsal groove extending along the second to fourth vertebrals. The first and fifth vertebral scutes are very broad, the second through fourth may be slightly longer than broad, and the fifth is laterally expanded. Vertebral and pleural scutes may be rugose with growth annuli. Marginals 1, 2, and 8-10 are slightly expanded but not flared, and 3-7 are often slightly upturned. The carapace is highest just behind the center and broadest at the level of the anterior part of the eighth marginals; its posterior rim may be weakly serrated. The carapace is dark to blackish brown, but may be light brown in some. J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Its natural habitat is subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains.

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.

Chelidae
Chelidae is one of three living families of the turtle suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America. It is a large family of turtles with a significant fossil history dating back to the Cretaceous. The family is entirely Gondwanan in origin, with no members found outside Gondwana, either in the present day or as a fossil.Georges, A. & Thomson, S. (2006). "Evolution and Zoogeography of Australian freshwater turtles". In: Merrick, J. R.; Archer, M.; Hickey, G. & Lee, M. (eds.) ''Evolution and Zoogeography of Australasian Vertebrates''. Sydney: Australia. Description Like all pleurodirous turtles, the chelids withdraw their necks sideways into their shells, differing from cryptodires that fold their necks in the vertical plane. They are all highly aquatic species with webbed feet and the capacity to stay submerged for long periods of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Platemys
The twist-necked turtle (''Platemys platycephala''), also known as the flat-headed turtle, is distributed widely across northern South America. Twist-necked turtles have extremely flat shells that help them hide from predators under rocks and debris. When threatened, this turtle withdraws by twisting its head into its shell. ''P. platycephala'' is the only species of the genus ''Platemys'' and occurs in northern and central South America. ''Platemys platycephala'' means "flat turtle, flat-head" and accurately describes the structure of the head and shell. This species inhabits shallow creek beds and frequently forages on the floor of the Amazon rainforest for insects, amphibians, and mollusks. Camouflage, head and body shape, and advanced sexual anatomy allow this species of turtle to effectively populate much of South America. Mating occurs during rainy months (March–December) and egg deposit occurs during dry months (January–March). Males have been known to behave aggressiv ...
