Its natural range extends from southeastern Canada, southwest to the Rocky Mountains (and beyond, where introduced), throughout Mexico, and as far south as Ecuador. This species and the larger alligator snapping turtle are both widely referred to as snapping turtles or snappers (though the common snapping turtle, as its name implies, is much more widespread overall). Spiny softshell The spiny softshell turtle (Apalone spinifera, formerly Trionyx spiniferus) is a species of softshelled turtle, one of the largest freshwater turtle species in North America. They get their name from the spiny, cone-like projections on the leading edge of their carapace, which are not scutes (scales). The spiny softshell has a wide range, extending throughout much of the United States, as well as north into the Canadian provinces of Ontario and Quebec, and south into the Mexican states of Tamaulipas, Nuevo León, Coahuila, Chihuahua, Baja California, Morelos, and Honduras.

This is a frog of larger, permanent water bodies, swamps, ponds, lakes, where it is usually found along the water's edge.
