Alamos, Sonora, Mexico. August 22, 2011.
I first saw this species at the Sonora Desert Museum in Arizona, where they live on the grounds but don’t seem to be spreading to the surrounding area. My first ‘wild’ macrolopha was in the town of Alamos, close to our hotel. These large lizards have taken up residence among human habitations, and seem to be doing well. This first Sonoran ctenosaur is a young adult; babies are bright green, which changes to a muddy brown when they reach adulthood.
