Camouflage Frog (Pseudacris cadaverina)

A small oasis in the Sonoran Desert with a spring burbling between granite rocks. How do these frogs make it into isolated water in the middle of nowhere? 


Cryptic coloration makes these treefrogs difficult to spot when sitting on a granitic rock.

Look at the same image a bit smaller. Blends in pretty well doesn't it?
