This species have extremely long necks, usually as long or longer than the carapace. These carnivores feed on anything small enough to seize and swallow, such … Safi A, Khan MZ (2014). Any scaliness or cuts on the turtle's shell might indicate a turtle that has suffered an injury, which could mean it has other less obvious health issues as well. Bulletin of the Florida State Museum, Biological Sciences 3:181–324. [15] The trionychine softshells are more biologically diverse.

An outdoor enclosure needs to be fully secure and escape proof, a pond of 120cmx120cm and at least 60cm deep would comfortably house three – four adult turtles. The turtle’s carapace is grey, olive green or brown in color. The carapace is flatter, and not as steeply-domed, as that of other sea turtles. The onset of sexual maturity will occur anywhere from 5 – 8 years of age. [3], The carapace length of L. punctata has been known to range from 240 to 370 mm (9.4 to 14.6 in). Final report.

They use these nests more often in areas with limited nesting habitats and/or during years with heavier precipitation when high water levels and flooding further reduce the number of suitable nesting sites.

As the turtle ages, these colors fade and are lost, resulting in the dark-brown coloration characteristic of adults. The numerous species of softshell turtles lack these scutes, and instead have pliable, leathery shells.
