So today is the first day of the second week of the Marine Bio course! We dissected a starfish and a squid while discussing how they were classified, how they were structured, and how they behaved. What I found interesting was that even though they lacke brains, animals such as seastars and jellyfish still possess nerve nets that help them detect movement or touch. Another thing I found interesting was about the anatomy of a jellyfish. I learned that, because their body consists of more than 90% water, the jellyfish can grow large on a low metabolism. This is because a good majority of its body is not composed of entirely composed of its own cells and, as a result, it does not have to feed so often to provide its body with energy.
We discussed a couple articles today as well. There was one article that left me a little concerned and confused. The coral polyps that have been eaten by the butterflyfish do not seem to recover anymore. What concerns me is that there doesn’t seem to be an immediate of efficient solution to the problem. Do we just sit back and watch? How can we take action and promote others to take action? How do we get people to CARE for organisms (especially those we don’t have much in common with)? These are the questions I search for answers for.
P.S., our squid was female. There were so many eggs…It was like corn…
