Northern Map Turtle (Common Map Turtle)
Northern map turtles are small- to medium-sized and have a low ridge along the center of the upper shell. The hind edge of the upper shell is strongly serrated. The upper shell normally is brown or olive-brown with a netlike pattern of fine yellow lines, giving the shell the appearance of a road map. The lower shell of this species is light yellow; the seams between scutes are dark brown. The head and limbs are brown with thin yellow lines. A small yellow spot is present behind each eye.
