Which shows that a recent scientific discovery shows that Bearded Dragons amoung many other previously unknown types of reptiles are venoumous. In fact the venom they carry is simular to that of a rattlesnake. But that the vemon is in such a weak amount that it it completly harmless to humans. The glands are very small and the poisen so minute that it only effect small rodents and insects. Pretty interesting eh?
I have only recently found these articles and havent looked into finding them to be disproven so take this for what it is. something I found on the internet that seems to have factual scientific background to it.
