Pic for Today: Chuckwalla! (Mexican Spiny-tailed Iguana)
I thought this was a Chuckwalla,  another local lizard that makes itself at home on the grounds of the Arizona Sonoran Desert Museum. There is an enclosure, just before you enter the museum gates, where Chuckwallas and other Sonoran lizards are supposed to be on display, but, honestly, they are hard to miss on any visit to the museum if you just keep your eyes open wherever you find large rocks (real rocks or the fake rocks the museum use to build displays…the Chuckwallas do not seem to care). This large male was displaying on a rock near the Mountain Canyon displays, which is where I have encountered the Chuckwalla most often at the ASDM. The panel shows the same specimen: full body (though the tail is curled around behind and below) and close up.

Note: This is actually a cross between a Mexican Spiny-tailed Iguana and a San Esteban Island Spiny-tailed Iguana…unique to the grounds of the Desert Museum…introduce there in the 70s and still breeding.
