The phylum mollusca includes three major classes, one of which is the cephalopoda class. The major defining characteristics of the cephalopoda class are a visceral mass, a mantle and a muscular foot. All of which can be seen on the Fitch octopus that our group found today in the soft bottom intertidal Cholla Bay. Seeing one of these creatures was absolutely amazing. I even got to see it shoot its ink! I have never even thought about what it would be like to have one of these in my hand, but today I got to experience it and it was awesome. Hopefully as my time in Puerto Penasco continues, I will get to see even more of the amazing creatures.
