Document Summary
****next exam scheduled for march 21st - review session monday evening before. We left off last class discussing aspect ratio of fish tails and the swimming performance of fish. Aspect ratio: caudal fin height squared divided by caudal fin area. The taller the fin, the smaller the area, the higher that equation is going to be. High aspect ratio tail - tall tail without a lot of area - not a lot of drag. This is equivalent to sprinters vs. marathon runners. For endurance swimmers, you will see more red muscle, darker because of a presence of. In burst type swimmers are more white muscle, anaerobic powerful muscles a protein called myoglobin which stores oxygen in the muscles and makes it so dark. Bony fish have greatest diversity of any vertebrate group. You can find them throughout water column and any place where there is water on the face of the earth, fish will survive.
