Venomous lizards are fascinating reptiles that possess the ability to deliver venom through their bites. One of the most well-known examples is the Gila monster, which is native to the southwestern United States and parts of Mexico. These lizards have specialized glands in their jaws that produce venom, which they use primarily for defense and to subdue prey. Another intriguing species is the Mexican beaded lizard, closely related to the Gila monster. Both of these lizards have a stout body and a distinctive appearance, with bead-like scales. While their venom is not lethal to humans, it can cause pain and swelling, reminding us that even seemingly harmless creatures can have surprising adaptations.
