This lifeform is found in the SW USA (Texas, New Mexico, and Arizona). This lifeform is found in Mexico.

Texas banded gecko (Coleonyx brevis) is found from New Mexico and Texas south into Mexico.

Coleonyx genus is found from Mexico south to Costa Rica.  Several of the species are found in deserts and others in tropical lowlands.  There are seven species in this genus.  The movable eyelids and vertical pupils and a body and tail with darker bands help identify this genus.

Geckos (Family Geckonidae) are found worldwide, are generally  friendly and eat lots of insects, which makes them beneficial.   Many of the species in this family make excellent pets.

Lizards and Snakes (Squamata Order) share many common characteristics and consequently they are grouped in a single order. There are greater differences between some groups of lizards than there are between other groups of lizards and snakes. The same is true of snakes. Lizards and snakes share a common skull shape.

Reptiles (Class Reptilia) are an ancient group of scaled  chordates. These scales may be permanently joined, as in the  turtles, or flexible, as in the snakes. Reptiles are land-based. Their eggs are laid on land and the young are air breathing.

Backboned Animals (Phylum Chordata) are the most advanced group of animals on earth. These animals are characterized by having a spinal cord or backbone. Most members have a clearly defined brain that controls the organism through a spinal cord. Fish, amphibians, reptiles, birds, and mammals are in this phylum.

Currently, some taxonomists believe that the fish should be divided into two groups (sharks and regular fishes) and that there are some other primitive groups in the phylum such as hagfish or lampreys.

Animal Kingdom contains numerous organisms that feed on other animals or plants. Included in the animal kingdom are the lower marine invertebrates such as sponges and corals, the jointed legged animals such as insects and spiders, and the backboned animals such as fish, amphibians, reptiles, birds, and mammals.
