Anaxyrus microscaphus
—
Arizona Toad
The genus Anaxyrus was split from Bufo by Frost et al in 2006. This split is particularly controversial among herpetologists, and many references still use the long-established Bufo.
Several of these toads were under rocks in the creek, letting out occasional plaintive yelps when we got too close.
