Ctenosaura macrolopha — Sonoran Spiny-tailed Iguana
Some other names for this species:
Mainland Spiny-tailed Iguana
Adult spiny-tailed iguanas are large and wary. This one was perched atop a roadside post perhaps eight feet up, keeping a wary eye on us. It reminded me of a wary and high-perched bearded dragon I had seen in Australia.
Juvenile spiny-tailed iguanas are also wary, but much smaller and spryer and greener. This one scrambled back and forth across a large boulder, trying its best to prevent us from getting a good angle for photos.
A typical view of one of these shy iguanas, sneaking into the nearest hidey-hole.
