General Description: Southwestern Woodhouse's Toads are a large olive to gray-brown or black toads with scattered dark spots on the back and a light stripe running down the center of the back. The cranial crests are large, and the parotid glands are long and diverging. The cranial crests contact the parotid glands. The voice sounds like the nasal wail of a crying baby.
