The beaded lizard or Mexican beaded lizard (Heloderma horridum) is found in Mexico and the southern United States. Along with the Gila monster (Heloderma suspectum), it was thought until recently to be one of only two lizards known to be venomous, until research showed that some iguanas and monitor lizards also produce venom [1]. Their venom is similar to that of some snakes (e.g., the western diamondback rattler). There are a number of subspecies, including H. h. exasperatum, H. h. alvarezi, and H. h. horridum. Adult Mexican beaded lizards range from 13 to 18 inches (33 to 46 cm) in length.
