Mexican beaded lizard

The Mexican beaded lizard is a lizard found in Mexico that grows up to 18 inches in length. Along with the Gila monster, it was once thought to be one of only two lizards known to be venomous. However, recent research showed that some Iguanas and Monitors also produce venom. Their venom is similar to that of some snakes.
