Notes

Gila Monsters do not have fangs like venomous snakes. The teeth in their lower jaw contain two grooves. When the Gila Monster bites, venom from glands in their lower jaw flows up the grooves into the wound. The Gila Monster will chew on its victim to facilitate the flow of venom. The Gila Monster has powerful jaws, a strong bite, and is said to hold on like a bulldog.
