In the lab experiment I expect to understand and be able to apply my knowledge regarding fish and mammals to the dissection of the perch and observations of the shark and lamprey. I also will study a perch hands on, once it is dissected I will be able to recognize the various systems and better understand how they work and differ from that of a human. I will also be able to use my new knowledge of mammals and fish to observe the vertebrates have adapted to their living environment.
