Notes: Acoelomates and Pseudocoelomates To Pseudocoelomates Acoelomates Platyhelminthes These are flatworms, flukes and tapeworms. They have a gastrovascular cavity (no body cavity), true muscle tissue, and moderate levels of cephalization. Turbellaria. This class of acoelomates includes free-living marine organisms. The most well-known example of this class is Planaria Planaria is one of the few aquatic turbellarians. In it, nitrogeneous waste diffuses through the ectoderm. Planaria lack gas exchange and circulation specialization. It has a fine-branching gastrovascular cavity, a simple excretory system that functions only when osmotic forces are balanced and a flat shape - so all the cells are close to water. Osmoregulation is regulated by ciliated cells called flame cells that move water in and out of the flatworm. Flatworms move via cilia on the ventral side where mucus is often secreted when not "swimming" (for a planarian to swim it undulates). Eyespots detect light and lateral flaps locate pheromones. Trematoda and Monogenea.
