Today, we started out, not by discussion, but by going straight into the lab to do what i believe is our last dissection. We got our dogfish shark that we had begun dissecting yesterday, and began removing the skin and skull, bit by bit, from the top of it’s head, in order to see the brain. After that, we found each part that was pointed out by the guide. Once we were done with that, we cleaned off, packed up, and went back into the classroom.
Once we got into the classroom again, we started discussion by talking about an experiment that wanted to get a closer look at dolphin and their echolocation. They found that, as the dolphin gets closer to food, the clicks become lower, and they get closer together. We theorized that this is because as the dolphin gets closer, it needs to know where the fish is more precisely. They also would want to catch the fish off guard if possible, hence the lowering og the volume. We then talked about an article about how tempurature can effect the growth rates of coral. The article said that the normal water tempurature, 27.5 degrees, Celcius, was the lowest mortality rate. What i found interesting, though, was that at the higher tempuratures, the larva matured faster. It made me wonder if that was because of certain enzymes, or something else.
Tomorrow, me and my group have to teach the class about sea turtles. My job is to teach about the anatomy. I love turtles, so I’m very excited.
