Close-up of the world's largest natural beaded lizard

The bumps on the skin of the endemic Heloderma charlesbogerti lizard in southeastern Guatemala look like their bodies were beaded.

Guatemala beaded lizards are also capable of secreting venom.

With fewer than 200 individuals still living in the wild, the Guatemala beaded lizard is one of the most endangered reptiles in the world. Guatemala beaded lizards are also capable of secreting venom. But their venom is only used in self-defense, not when attacking prey. The main food of this slow lizard is bird eggs. They can live to 60 years of age in the wild.
