Found about 6" underground while I was digging potatoes in the garden. This toad vocalized loudly when I first disturbed it (with my fingers, not a shovel). Then it crawled deeper into the mud.
Bufonidae is the family of the true toads, members of the order Anura (frogs and toads). They are the only family of anurans in which all members are known as "toads." The bufonids now comprise more than 35 genera, Bufo being the most widespread and well known.
