Bark anoles are another non-native species of anole in south Florida, although they've been around long enough (more than 50 years) that some authorities (including the SSAR) distinguish the ones in Florida as a distinct subspecies. They spend their time clinging to trunks and large branches of trees, and this picture shows that they've evolved a good camouflage for this lifestyle.

Todd Jackman has an excellent anole site that discusses the parallel forms and lifestyles that different sets of anoles have evolved on different Caribbean islands.

Here's another bark anole from South Florida deciding how much longer to wait before dashing out of sight. (The answer -- one more shutter snap.)

A couple of Christmas Day bark anoles showing off their camouflage, if such a thing is possible.

I like to think that this is the spot on the tree where the day shift workers check out and the night shift workers check in. In this case, the day shift worker (on the right) is the non-native Bark Anole, and the night shift worker (on the left) is the non-native Wood Slave (one of my favorite standard English herp names).
