What did you already know of the material presented in the lesson?

I already knew several things about today's lesson. I previously found out that the tree octopus website was illegitimate. I found out that tree octopus' did not exist in sophomore year in Global Technology. In Global Technology, my teacher wanted us to research the tree octopus. Through him I had already revealed to myself that the tree octopus is fictional. He had also taught us that the pictures were photoshopped. Also, the majority of links from the tree octopus sight either led to another zapatopi.net name or wikipedia, which, can be editted by anybody. This is what I already knew about today's lesson.
