There is a fascinating itsy bitsy spider living in my bathroom. Its longevity is astounding! So I searched for spider info online. The marvelous European site (and more particularly its page on spider anatomy) "...contains more than 1300 pictures of 348 spiders in 162 genera commonly found in NW-Europe..." The poster below was created by the brilliant artist(s) at Charts and Diagrams at Zazzle. They derived it from a Wikipedia featured picture meaning it has been identified as one of the finest images on the English Wikipedia! The diagram is included on the European spider site as well. It would be a great gift for a biology teacher. Click on the image to buy or learn more.
