Open encyclopedia reference
Gastrophryne olivacea, the Great Plains narrow-mouthed toad or western narrow-mouthed toad, is a species of microhylid frog found throughout much of the south-central United States from Nebraska south through Texas, and into northern Mexico. Though not a true toad, evidenced by the smooth, moist skin, its common name is due to its terrestrial habit.
