Great Plains Toad (Anaxyrus cognatus)
Description: 3 - 4 inches. Great Plains Toads vary in color from brown, green, or gray, with large dark blotches on the back. The belly is plain white, but may occasionally have some spots. There are two large glands on the back of the head (parotoid glands) that touch the ends of the end of the small ridge behind each eye (cranial crests). The cranial crests meet in front of the eyes to form a point.
