Fakta

It is one of only two venomous beaded lizard species, and the only lizards known to have evolved an overt venom delivery system, along with the rest of its genus.1

Some compounds in its venom are being studied for possible treatments of diabetes, Alzheimer's disease and HIV. One of them, exendin-3, is the basis of the drug exenatide.1

The beaded lizard is immune to the effects of its own venom.1

It is larger than the Gila monster, with an average adult weight of 800 g, and large specimens exceed 2,000 g.1

Beaded lizards have forked pink tongues that they use to smell, with the help of a Jacobson's organ.1

Young beaded lizards are rarely seen, as they are believed to spend much of their early lives underground.1
