Trionychidae is a family of turtles, commonly known as softshell turtles or simply softshells.The family was described by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish waters.
The shell of a turtle is unique among vertebrates and serves to protect the animal and provide shelter from the elements. [13] [14] [15] It is primarily made of 50–60 bones and consists of two parts: the domed, dorsal (back) carapace and the flatter, ventral (belly) plastron. They are connected by lateral (side) extensions of the plastron ...
Geoemydidae are turtles of various sizes (from about 10 to 80 cm (4 to 30 in) in length) with often a high degree of sexual dimorphism.They usually have webbed toes, and their pelvic girdles articulate with their plastrons flexibly.
Mata mata turtles are readily available in the exotic pet trade and are quite expensive to obtain. Due to their unique appearance, they make interesting display animals. They also grow quite large. However, mata matas are not active hunters, so, like the alligator snapping turtle, they need less space than a large, active species.
These eggs have a leathery, flexible shell and they typically measure only 26-28 mm in diameter. [24] Incubation time is temperature-dependent, ranging from 9 to 18 weeks. One study on the incubation period of the common snapping turtle incubated the eggs at two temperatures: 20 °C (68 °F) and 30 °C (86 °F).
