Lizard venom refers to the toxic substances produced by certain species of lizards, which can be used for defense or to subdue prey. Unlike snakes, most lizards do not possess venom, but a few, such as the Gila monster and Mexican beaded lizard, have evolved venomous capabilities. Their venom contains a mix of proteins and enzymes that can cause pain, swelling, and other physiological effects in their victims. Research into lizard venom has potential medical applications, particularly in pain management and treating conditions like diabetes. The unique properties of these venoms are being studied for their ability to influence biological processes, which may lead to the development of new pharmaceuticals.
