Gila monsters are desert-dwelling lizards known for their venomous bite. Synonyms for these creatures include Heloderma suspectum, bead lizards, and Gila beaded lizards. They can be found in areas of Arizona, Nevada, and Mexico, where they live in rocky outcrops and riparian areas. These lizards are heavy-bodied and have a tough, bumpy skin that helps them retain water in their arid environment. Although they are venomous, they are not aggressive and will only bite if provoked. Despite their intimidating appearance, Gila monsters play an important role in their ecosystem, preying on small animals and serving as a food source for larger predators.
