Compare two species

Eastern Spadefoot vs. Fowler's Toad

Look at the eye first. A vertical, cat-like pupil means Eastern Spadefoot; a true toad such as Fowler’s has a horizontal pupil. Then behind the eyes: a true toad has large, raised glands (parotoids) and bony ridges on the head. A spadefoot’s head is smooth, with no crests, and it lacks the big toad glands.
