Yes, Gila monsters (Heloderma spp.) are venomous reptiles. They are one of the few known venomous lizard species. Gila monsters produce venom in specialized glands located in their lower jaws. They deliver their venom through grooved teeth when they bite their prey or defend themselves.

The venom of Gila monsters contains a mixture of toxins that affect various physiological processes in their prey. It’s important to note that Gila monsters are generally slow-moving and non-aggressive, and they rarely bite humans. However, if provoked or handled improperly, they can bite and inject their venom. If you encounter a Gila monster in the wild, it is best to observe it from a safe distance and avoid any attempts to handle or disturb it.
