Venom is a powerful substance used by many creatures on this planet, but how does it work? What purpose does it serve? The good folks at NOVA have crafted this fine documentary on venom in order to "track down and capture the world's most venomous animals." Visitors to the site can watch the program in its entirety, read a complete transcript of the program, and also learn more about the participants. The distinguished members of the team include Bryan Fry of the University of Melbourne, Greta Binford of Lewis & Clark College, and Zoltan Takacs of the University of Chicago. The program takes visitors around the world as the participants attempt to gain insights into the world of venom, and viewers will not fail to be amazed by their discoveries. The site also includes twelve different related links, including additional video clips on leeches, lizards, and the very timely Making Vaccines.
