Synonyms: Scaphiopus hammondii

Wikipedia Abstract

The western spadefoot toad (Spea hammondii) is a relatively smooth-skinned species of American spadefoot toad. Its eyes are pale gold with vertical pupils. It has a green or grey dorsum often with skin tubercles tipped in orange, and it is a whitish color on the ventrum. It has a wedge-shaped black spade on each hind foot. Adult toads are between 3.8 and 7.5 cm (1.5 and 3.0 in) long. Juvenile western spadefoot toads look similar to adults, but have more distinct spotting.
