body cavity presence

acoelomate - such as flatworms (tapeworms) do not have a coelom between the digestive system and the outer body wall
pseudocoelomate - such as rotifers and round worms (hookworms), the coelom is derived from both the endoderm and mesoderm
coelomate - (true coelomates) is derived from only mesodermal tissue.
