Southern Black Widow Spider
The black widow spider is famous for its interesting mating habits. But itís silk, especially whatís called dragline silk, is pretty special too. Dragline silk is one of seven kinds of silk that an individual spider produces. Itís the silk that provides the structural foundation of the spiderís web and supports the spiderís body as it moves around. It turns out that black widow dragline spider silk is super strong and stretchy compared to most other silks. Which makes it an attractive item for humans to try to copy or modify for use in lightweight but strong clothing or even body armor. (Scientific American, June 13, 2007)
