Plains Spadefoot in
The Plains Spadefoot is 1.5 inches to 2.5 inches long. The record size is 2 9/16 inches. It has a pronounced boss between the eyes. The color varies from gray to brown and often has a greenish tinge. There are four vague longitudinal stripes often present on its back. The small warts on its back are tipped with yellow or orange. Vertical pupils are like a cat's. Hind legs have single, wedge-shaped tubercle, or spade on inner surface. Toes are webbed. The skin is relatively smooth and moist like a frog, but they have some warts on their backs and live on land like a toad.
The male Plains Spadefoot's call is loud and harsh and may carry up to 3 kilometers.
