Description
This species (Woodhouse's Toad) is large for a toad, with normally proportioned limbs and a blunt snout. Its paratoid glands are narrow, and spread apart by more than one (parotoid) length. Cranial crests run lengthwise from the front of the eyes to back edge of the eyes, then turn sharply towards the side of the toad and extend to the outside edges of the eyes. The warts are dark and small. Each wart has a red spot at its tip. The toad is olive green on its dorsal side, with dark splotches and a pale stripe down center of back. The underside is creamy and unmarked, while the throat is slightly darker in color.

Subspecies include Anaxyrus woodhousii australis (Southwestern Woodhouse's Toad), A. w. velatus (East Texas Toad) and A. w. woodhousii (Woodhouse's Toad or Rocky Mountain Toad).
