I enjoyed this very good presentation about the octopus. However, I wanted to point out to Tara and to anyone else viewing this that the Pacific Northwest tree octopus DOES NOT exist. It was an internet hoax created in 1998 by Lyle Zapato and continues to be perpetuated by him and many unsuspecting victims. One very well written article on the matter is "Tentacled Tree Hugger Disarms Seventh Graders" written by Matthew Bettelheim, March 14, 2007. That article was published by Inkling Magazine.com and can be found at: https://web.archive.org/web/20070320203138/http://www.inklingmagazine.com/articles/tentacled-tree-hugger-gets-legs-up-on-twelve-year-olds/ If you do your research, you can find plenty of other corroborating evidence of this hoax.
