The Texas horned lizard (Phrynosoma cornutum) also called the horny toad or horned frog, is in decline in most of the state of Texas except West Texas, according to Russell Martin, a wildlife biologist with the Texas Parks and Wildlife Department. West Texas is where there are large oil and gas exploration fields, and where the fight over the proposed endangered species listing of the Dunes Sagebrush lizard (Sceloporus arenicolus) occurred over the last few years. That lizard was not put on the endangered species list. According to the Lubbock Avalanche-Journal, the lizard is doing fairly well in areas of West Texas, but is in decline in Central and East Texas. Martin attributes the decline to urbanization and the drop in harvester ant populations, the main food source for the lizard. The use of pesticides on invasive fire ants has contributed to the drop in harvester ants.
In addition to Texas, the lizard can also be found in southwestern Missouri, Kansas, much of the Southwestern United States and Mexico. It is against the law in Texas to kill the horned lizard or to collect it and keep it as a pet. While horned lizards are probably the coolest looking reptiles in North America, unless you have a steady supply of harvester ants (these lizards eat thousands of ants everyday) they are virtually impossible to keep.
