Are bearded dragons poisonous?

According to the most recent research by Dr. Brian Fry of the University of Melbourne, bearded dragons are venomous. The researchers found venom similar to rattlesnake venom in bearded dragons. This is what they now believe causes the swelling when one is bitten by the lizard (they used to think that it was bacteria). Their delivery system is so primitive though that the venom is not really dangerous to humans except to cause pain and swelling.
