Open encyclopedia reference
The Canadian toad (Anaxyrus hemiophrys), also known commonly as the Dakota toad, is a species of toad that ranges from the prairie regions of western Canada south to parts of the upper midwest of the United States. It belongs to the family Bufonidae, the "true" toads. Its specific name is derived from the Latin word hemiophrys, meaning eyebrow, which refers to its pronounced cranial crest between and behind the eyes. Anaxyrus hemiophrys displays the typical toad characteristics: it lacks a tail and teeth, it has a horizontal pupil, and its dry skin is thick and warty.
