Definition
Helodermatidae is a family of venomous lizards, including the Gila monster and the beaded lizard. These lizards are characterized by their stout bodies, blunt tails, and distinctive beaded scales. They are native to North America and Central America. Think of them as the bad boys of the lizard world, armed with venom. Unlike most lizards, they use venom as a defense mechanism, not for hunting.
