Helodermatidae

Heloderma consists of venomous lizards native to the southwestern United States, Mexico, and as far south as Guatemala. Their closest living relatives are the anguid lizards. They are large, stocky, slow-moving reptiles that prefer semiarid habitats. Members of the family are venomous. Venom glands are located in their lower jaws, unlike snakes' venom glands, which are located in their upper jaws. Also, unlike snakes, helodermatids lack the musculature to inject venom. Helodermatids are carnivorous, preying on rodents and other small mammals, and eating the eggs of birds and reptiles. They are oviparous, laying large clutches of eggs.
