Spiny softshell turtle (Apalone spinifera)

A spiny softshell is a sizeable aquatic turtle, one of the largest out of most freshwater turtles. They get their name from the structure of their shells which have cone-like projections at the edge of their carapaces.

Also, you can recognize a spiny softshell by its soft, fleshy, and elongated nose. Furthermore, they have webbed feet with three claws on each. 

Their diet consists of crayfish, aquatic insects, fish, and aquatic plants. A unique feature of spiny softshells is their ability to breathe oxygen and carbon dioxide while breathing air or underwater2. This breathing ability makes them bimodal breathers.
