Pictured here is a coast horned lizard (Phrynosoma cerroense) on Baja, California's Vizcaíno Peninsula. Coast horned lizard populations are declining from southern Baja, California to northern California for many reasons including loss of lowland habitat from agriculture and urbanization and the introduction of Argentine ants, which displace the more nutritious harvester ants that these lizards feed on.
