Anolis gundlachi, the yellow chinned anolis in El Yunque forest, Puerto Rico

I saw this Anolis in el Yunque forest.  The anolis was in a shady area under the canopy.  It kept moving away and hiding which didn't make taking his photos any easier.

Anolis pulchellus, Aguadilla, Puerto Rico, this anolis is of the type that lives in grasses and bushes but never on trees

I took the photos in my orchid shade house in the town of Aguadilla, Puerto Rico.

Anolis evermanni Stejneger 1904, in the forest of Rio Abajo

Today I was cleaning the patio and decided to remove an accumulation of sticks and leaves that had developed under a clump of palm stems.  When I did this, I broke several tunnels that termites had made into the leaf litter mass.  As a result worker termites were exposed, as well as a few warriors.  This is not an unusual event so I continued cleaning.  Then I noticed that an Anolis evermanni was eating the worker termites.  Anolis evermanni are normally an even green color.  This one had an overlay of darer green bands.  I attribute this to the excitement caused by the presence of an abundance of prey.  Anolis evermanni has shown a breathtaking amount of behavioral flexibility in the laboratory.  From what I saw while taking the photos, this particular lizard regarded me as an annoyance, but also as essentially harmless.  That's why I could get so close to it.  These lizard see me daily as I do garden chores or just walk around.  This might explain the boldness of this one, or maybe it was very, very hungry.  Anolis only eat the workers, the warriors have dark pointy heads full of a distasteful toxic glue that the lizards seem to loathe.

Anolis cristatellus, displaying its dewlap

Compared to most other lizards I see locally, this male Anolis cristatellus has been surprisingly bold.  Instead of running away up the tree or hiding on the opposite side of the trunk, this lizard has held its ground calmly but alertly.  It had allowed me to get very close to him.  On ocassion it has showed its dewlap, this is a territorial display in this species.  Today I was able to get images of the lizard showing its dewlap.

Anolis cristatellus cristatellus Duméril and Bibron, 1837, that just had been involved in a territorial fight

This adult male cristatellus was just involved in a territorial fight.  The snout shows damage and the lower mandible is slightly bloody.  These lizards engage in territorial fights with neighboring males.  Sometimes, when they fight, they make hissing noises.  The fights usually happen in branches or trunks of trees or bushes.  In those fights that I have witnessed the loser is the one that falls from the trun or branch.

Anolis curvieri eating a tarantula

In January of 2013, I noticed that there was a large lizard eating, with some difficulty, a tarantula it had caught.  Apparently, this normally canopy dwelling animal, saw the tarantula in the ground and decided that it was just a too tempting a prey to pass up.  I was able to take a number of photos before it headed back up to the canopy.  The color of this particular animal is unusual as it is rare to see brown adult individuals, it is even rarer that this form is photographed.  The normal color for adults of this species is green, inmature individuals are brown.  Note the very long tail, more than twice as long as the whole body.

Anolis cristatellus, the camouflage fail of rorschach patterned headed lizard

Generally the local immature Anolis cristatellus are quite a wary bunch.  Given that pretty much every predator around would love to snack on them, including the adult A. cristatellus, their alert demeanor is understandable.   The color of these immature lizards resembles quite closely the leaf litter.  When standing on the forest floor these small lizards are well camouflaged and virtually invisible.  But when these lizards step away from their normal background the color pattern makes them quite conspicuous.  Normally it is not easy to get close to these lizards because they are prone to run away quickly if they become even slightly alarmed.   But this lizard seemed to feel so comfortable perching on the flowers of this Renanthera orchid that it showed an unexpected reluctance to move away.  This allowed me to get close enough to it to take several photos against a background that highlights its camouflage pattern.  The fact that the lizard lacks the tip of its tail means that even a good camouflage is no guarantee of survival in an environment full of hungry and sharp eyed predators.
