Is anaconda considered venomous?

These days no, Anacondas do not produce a venom. Well kinda. But there has been recent debate as to whether they (as well as other constrictors) once had venom. They do have what appears to be remnants of venom glands but they are for the purpose of saliva. Bryan Fry of the University of Queensland has found though that these glands still produce venom like proteins but they are in trace quantities and no longer used for killing and catching prey. He feels that in venomous animals if they stop relying on venom over generations these animals lose that ability over many thousands of years. So I guess it depends on your definition of venomous. They still produce minute amounts but can but it wont hurt us or any other animal really.   Many animals we once thought of as non venomous actually are such as iguanas and certain species of garter snakes. While not extremely toxic we now know these animals do have working venom systems. From what I understand it started with Fry looking into komodo dragons and the myth that they had super toxic saliva with various pathogens and bacteria. In reality they have venom. Anyone who wishes to learn more about venomous animals should really look into Bryan Fry. He has some books which I cant wait to read and he IMHO has revolutionized what we know about venomous animals. And my apologies to him if I misinterpreted anything I have read or seen in his lectures.
