A puff adder's bite can do serious damage, even to an animal with skin as thick as a rhino's. The photographic evidence we have is not pretty.
From the deserts of the American Southwest to the jungles and villages of Africa, vipers are notorious for their bad attitudes, diamond-shaped heads, and the longest snake fangs on Earth. But these snakes are not simply cold-blooded killers. The females have a softer side when it comes to family. Travel around the globe as we examine their maternal instincts. Then enter the lab as we dissect specimens in hopes of better understanding these viper queens.
