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.
