| Description: The acoelomates include two phyla, Platyhelminthes and Nemertea (otherwise known as the flatworms and ribbon worms). These animals do not have an internal cavity filled with fluid and also do not have a circulatory system. They have flat bodies, making all cells close to the surface so they can access oxygen. They don't have the ability to move it about on their own. They do have true nerve and muscle tissue.
