what is it?
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, it is often referred to as such because it is terrestrial.
