Frogs and Toads people confuse

Sonoran Desert toad or American bullfrog?

American bullfrog Not stated

NPS says it is sometimes mistaken for a bullfrog because of its size and smooth skin. The prominent parotoid glands mark it as a true toad.

Photos show typical adults; individuals vary. Never get close to compare.
