Stream Anole (Anolis oxylophus)
I found this attractively patterned anole clinging to a large boulder in a small stream, in plain sight, sound asleep at night. I disturbed its sleep to take a few photos. This is one of only a few anole species that live in close association with running water.

Stream Anole (Anolis oxylophus)
I found this juvenile of the same species prowling by day on a large fallen branch in the same stream as the anole in the previous pictures.

Some authorities put most of the Central and South American anole species (as opposed to the U.S./Caribbean ones) into the genus Norops. This will probably be the standard soon, but for now there are still many authorities using "Anolis". Also, some authorities consider A. oxylophus a synonym for A. lionatus. Thanks to Axel Fläschendräger for helping to identify this anole.
