Dissection Activity

This dissection activity may be one of the most interesting activity yet. By dissection different types of fish and invertebrates, I was able to identify different parts of the organisms. I thought that the stomach, intestines and wastes were the easiest parts of the organisms to identify. The intestines were fairly large which made it easily accessible and I was able to identify them. The fishes were much more easier than the invertebrates. If only I had a knife, I would be able to dissect and cut open the fish more easier. The scalpel was small and was not that sharp, making the cutting much more challenging. I thought that the invertebrates' different organs were hard to identify since they were small in size. The most significant part was most definitely it's waste because it has a certain color. For the dissection of the fishes, I found it hard to look at it's gills because it was filled with dirt and all the things that the fish has filtered.

Obviously the invertebrates did not have a back bone and I did not find any bones in them either. However, it's muscles and tissues were much more difficult to cut open than the fishes. Both organisms had intestines and I also noticed that both of the organisms had filters in them. The invertebrates were bivalves and they are filter feeders. The fishes had filters in their gills. I thought that this activity was very educational and we were able to view marine organisms at a different perspective.
