Brief SummaryRead full entry
At 7 inches or more, the Sonoran Desert toad is one of the largest toads native to North America. Adults have a uniformly green to greenish-grey topside of their bodies with a creamy white underside. Large white turbercles, or “warts”, are found at the jaw. They have relatively smooth skin aside from a few lumps on their hind legs. Recently metamorphosed toadlets will be tan to green with orange or red spots on the topside. Unlike other male toads in the region, male Sonoran Desert toads do not have dark throats. The males develop darkened, thick calluses on the inside of the thumbs of the forelimbs during the breeding season. They are toxic and eat mostly small rodents, insects and small reptiles. The Sonoran Desert toad burrows for eight to ten months of the year.
