Reticulated geckos can grow to 6.5 inches long, and are a pink or brown color with brown or black spots, sometimes with faint banding. They can easily be mistaken for Coleonyx brevis, as they share habitat, but Coleonyx reticulatus grows to a larger size.
C. reticulatus is nocturnal and carnivorous, consuming almost any small species of arthropod. They are found in semi-arid, rocky areas. They are capable of vocalizations, and sometimes will emit squeaking sounds if handled.
The reticulated gecko is listed as a threatened species in the state of Texas, as it only occurs in two counties, but its habitat is fairly remote and not easily accessible and is not under immediate threat. Also, part of its habitat is found within the protected confines of Big Bend National Park.
