Herpetofauna: One Life's List

Heloderma horridum exasperatum
Rio Fuerte Beaded Lizard

Sonora, Mexico
August 22, 2011

Late afternoon on a hot, humid day in southern Sonora.  We were walking up a mostly dry wash in search of Beaded Lizards, and sure enough, we found one, wedged into a crevice underneath a rock overhang.

Not as striking as a Gila Monster, but a beast nonetheless!
