This species was hidden well the only reason why i came upon it is we wondered off the trail and took a wrong step.
Scientific name: Phrynosoma modestum. Common name: Roundtail horned lizard. When they feel threatened they do not move, pretending to be a rock. Found at indio mountain research station May 22,2016 around 3 pm.
Very neat coloration on this P. modestum - nearly perfectly matches the surroundings in the Hueco Tanks area, as shown in the photograph. Was only able to spot the individual as a result of seeing it move.
Found at indio mountain research station this cutie was found trying to be a rock. A team member watched as it ran past and was able to see where it stooped. These guys are incredible at blending in with patches of desert rocks. It was pretty bright and hot out this day, 26.6C.
