The eastern spiny softshell is a medium to large softshell turtle with small bumps or spines on the front edge of the upper shell. There are dark spots on the fore- and hind limbs.

The midland smooth softshell is a rather plain-looking softshell turtle, with a smooth, rather featureless olive-gray or brown shell, and a light stripe bordered by black extending backward from each eye.

The three-toed box turtle usually has three hind toes. Its high-domed shell usually has a top ridge and is olive or brown with faint yellow or orange lines. Look for it in woodland habitats.

The northern map turtle is a medium-sized aquatic species with a low ridge along the center of the upper shell. A small yellow spot is present behind each eye. It occurs mainly in the Ozarks and the upper Mississippi River in northeastern Missouri.

The Ouachita map turtle is a medium-sized aquatic species with a prominent ridge down the center of the upper shell and bright yellow lines on the head and limbs. A large yellow marking behind each eye extends, narrowing, on top of the head. It occurs in southern and eastern Missouri.

Missouri has two subspecies of false map turtle. The northern false map turtle occurs in the Missouri River in central and northwestern Missouri and the upper Mississippi River. The Mississippi map turtle occurs in the lower Mississippi River, southern Ozark rivers, and southwestern Missouri.
