Woodhouse's toads are large toads reaching lengths of up to five inches. Their
coloration varies from green to light brown with a distinctive light stripe
down the middle of the back. They inhabit moist areas of western and southern
North Dakota. They are commonly found at night near the base of yard lights
where there is an abundance of insects.
Woodhouse's toads are named after the 19th century explorer, surgeon, and
naturalist, Samuel Woodhouse. These toads were formerly called "Rocky Mountain
toads."
