I dissected a Lamprey and it wasn't very exciting. You could see any feature of the animal because it wasn't very big. The one think that I saw that was pretty interesting was the anterior gill slits and the respiratory system. Those were the most viable to see and they were actually pretty interesting. My favorite part of this process was definitely the process leading up to the dissection. I learned a lot from researching about the animal and its habitats. I leaned that they have two main developmental stages, a laval stage and a stage in which it is at's normal phase but a little smaller. When they are in their larval stage they live in the river bottom in the sand, when they get older they develop a tolerance to salt water and move into more salty environment.
Today in Biology a group dissected a HorseShoe Crab. In this dissection I learned about many different things one being the the crab has 9 different sensors/eyes that help them navigate. There are a few on the dorsal side and also a few by its mouth. I learned depending on the crabs background the internal organs may be more or less distinct.
