Something you won't see on Animal Planet
Spider Kama Sutra
If you have never visited the wonderful world of Pharyngula, please do. This entry is about how spiders have sex (very carefully). Includes some really cool photos. There are also articles about squid and octopus sex that you should not miss, but the articles that track the attempts by the wingnuttia to change the very definition of science are hard to beat, and most of the comments are first rate.
