Octopus lab

I learned many facts about the octopus from this lab. First there are over 300 species of octopus. Also octopi release an ink to confuse their predators from attacking them. Octopi have special skin cells called chromatophore that give them the ability to blend in with their surroundings. Because they have no skeleton they are able to squeeze themselves into tight spaces. They also have very short life spans. It could be as short as six months to five years. Finally I learned that Octopi travel through the water by jet propulsion which releases a quick flow of water and also uses a lot of energy. Or crawling along the ocean floor which does not use as much energy.
The most interesting thing I did was taking the beak out. I had no idea they had beaks that were so similar to a bird's. The most disgusting thing I did was accidental popping his brain and all the pieces of it coming out. It was AWFUL!!! What I liked best was the opportunity to dissect an animal that I most likely will never have the opportunity to touch again and get a closer understanding of marine life. There was really nothing about the lab I didn't enjoy. If I were to change anything it would probably have just been the time frame.
