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 ...
Modern turtles have a horny beak without teeth in their mouth. In contrast, Odontochelys fossils were found to have had teeth embedded in their upper and lower jaws. [4] One of the most striking features of turtles, both modern and prehistoric alike, are their dorsal shells, forming an armored carapace over the body of the animal.
The flatback sea turtle was originally described as Chelonia depressa in 1880 by American herpetologist Samuel Garman.The genus Natator (meaning "swimmer") was created in 1908 by Australian ichthyologist Allan Riverstone McCulloch, and in the same scientific paper he described what he thought to be a new species, Natator tessellatus, thereby creating a junior synonym.

Green sea turtles are the most commonly traded species along Java's south coast and are sold in the form of whole, stuffed animals or turtle oil, locally known as "minyak bulus". [112] The geographer James J. Parsons' book titled The Green Turtle and Man played a special role in the conservation movement to save the species from extinction. [113]
Ninjemys oweni is an extinct large meiolaniid stem-turtle from Pleistocene Queensland and possibly New South Wales ().It overall resembled its relative, Meiolania, save that the largest pair of horns on its head stuck out to the sides, rather than point backwards, the larger scales at the back of its skull and the tail club which is made up of only two tail rings rather than four.
All have a unique pattern of wiggly, black markings or spots on their body and head. The diamondback terrapin has large webbed feet. [ 10 ] The species is sexually dimorphic in that the males grow to a carapace length of approximately 13 cm (5 in), while the females grow to an average carapace length of around 19 cm ( 7 + 1 ⁄ 2 in), though ...
