Spiny Softshell Turtle
The spiny softshell turtle buries itself in the mud at the bottom of ponds and lakes, using its long neck and powerful jaws to catch whatever prey swims by.

About This Species
The spiny softshell turtle is one of the largest freshwater turtle species in the country. Unlike other turtles, their shell is soft, flat, and rubbery with small spines along the edges. The turtle lives most of its life in the water, so its feet are fully webbed to help it swim and it has a long, pig-like snout that it pokes above the water to breathe without exposing the rest of its body.
