Venom found to be widespread in lizards

The finding that many lizards - including some that are common pets - are venomous is rewriting the family tree of lizards and snakes

People bitten by their pet lizard can suffer a painful swelling and prolonged bleeding. Infection by bacteria in the lizard's mouth was always assumed to be the cause, but it turns out that many lizards, including some that are common pets, are actually venomous. The finding is rewriting the evolutionary family tree of lizards and snakes.

"To find the classic rattlesnake toxins in the bearded dragon - a hugely popular pet - was a huge surprise," says Bryan Fry at the University of Melbourne, Australia, who led the work.

Venom was considered the preserve of advanced snakes and just two species of lizard, the gila monster (Heloderma suspectum) and the Mexican beaded lizard (Heloderma horridum). It was thought that these lizards evolved the ability to produce venom independently of the snakes.

i dont know, but i too am curious.

what im wondering though, is how these new lizards with supposed venom get it out, do they have glands like venomous snakes? to be able to use it to hurt humans, their teeth would have to pierce skin anyway, which alot cannot do as well as snakes.
