I think the most interesting of the dissections for me so far was the clam because it was so different from the rest of the other dissections. It has an incomplete digestive system and it has open circulation which means it has less internal organs than the other animals. They contain siphons, which the other animals don't have either, that takes in food/oxygen and releases waste/carbon dioxide. They also lack a brain/ganglia and doesn't move.
