Hmmm, a rambling reminiscence about amphibians and reptiles and of course to be continued, ‘cause here comes monsoon! The Sonoran Desert Toad, formerly the Colorado River Toad, is Incillius alvarius….formerly Bufo alvarius. As near as anyone can figure Incillius means ditch or trench and alvarius may refer to its large abdomen. A fun common name could be the Tubby Tummied Ditch Toad, but yeah, the Sonoran Desert Toad is an excellent name. And, a duded up Sonoran Desert Toad was the logo for the Tucson band The Dusty Chaps. The photos are mine.
