Gila monsters live in deserts and dry places of southern Nevada and California’s San Bernardino County. One isn’t likely to find them in open grasslands, as they avoid open areas. Meanwhile, as its name suggests, the Mexican bearded lizard is native to Mexico and southern Guatemala.
During combat, Mexican beaded lizards go for a high arch posture while pressing their bellies together. Meanwhile, male Gila monsters will twist their bodies in a wrestling bout.
Mexican beaded lizards and Gila monsters are foragers as they search far and wide for food. They typically feast on young rodents, frogs, snakes, earthworms, lizard eggs, and dead meat (carrion). Sometimes, they go as far as climbing trees to feed on bird eggs.
