Instead of tough scutes, their carapace is covered by soft, leathery skin. Different species of Softshell can found in most types of freshwater, but usually they prefer sandy or muddy bottoms. Softshells do bask, but are easily scared back into the water. Depending on species, basking is more common or rare. Like with other turtles, basking and drying out helps keep their carapace free of parasites and disease.
Females grow significantly larger than males.
While Softshells often get reasonably tame, they are not petting animals. Their sharp jaws can inflict painful wounds. Being active swimmers, captive Softshells must be kept in large aquariums. A long tank is recommended, to give them some room to move. The water should at least one foot deep.
