On a Friday morning, our biology class were tasked to dissect a squid. Our purpose was to locate and identify internal and external organs of a squid. This would help us relate to what we're learning in class by understanding the terms and using it to dissect a real life squid. I learned a lot like what a pen is, what an ink sac looks like, and where the funnel is located. While I'm not a big fan of dissecting anything, I think it's a good experience to have in a biology class. Interesting experience to dissect a squid and to see one up close and see its organs and so on.
1. 6 arms and 2 tentacles.
2. the arms are used. to swim, the tentacles to grab prey easier.
3. squid moves in the left direction while the water falls back in the right.
4. tentacles make it easier to grab food and small hooks around the suckers to pierce food.
5. a. mantle
b. visceral mass.
1. it has 4 gills
2. ink empties into the ocean to disguise the anmal's precense.
3. it serves as a site for muscle attachment . It is the remnant of a squid's shell.
4. through the anus.

It is cool to see the body plan up close isn't it? Good entry and great discussion of the Purpose of the dissection. Next time make sure to include facts from our class lesson on molluscs for the "connection to class" portion. You're also missing the photos needed to show each answer to the 9 questions. Were you able to get those in class?
