Origin
Phrynosoma cornutum is native to south-central and western United States. Texas horned lizards were introduced to the southeastern United States through the pet trade. In Texas, P. cornutum is listed as a threatened species.

Life Cycle
Pcornutum are flat-bodied lizards that have numerous horns on its head and body. Coloration is brown to yellow with fringed scales along the sides of its body and dark brown vertical stripes from the back its head to its back. Adult P. cornutum weigh 0.9-3.2 oz (25-90 g) and with males and females measuring 5.7 in. (144 mm) and 3.7 in. (94 mm), respectively. Texas horned lizards eat ants almost exclusively. Females lay 14-37 eggs during reproduction. Texas horned lizards are highly camouflaged with the ability to squirt blood from their eyes to confuse predators.

Distribution
Where populations of P. cornutum exist in the Southeast, populations are near the coast where the sandy dunes are similar to their native habitat. Florida, Georgia, and South Carolina have seen isolated populations.

Control Efforts
P. cornutum populations in the southeast are small and do not seem to be spreading. It is unlikely that Texas horned lizards will become invasive.
