pseudocoelomate animals have a pseudocoelom (literally “false cavity”), which is a fluid filled body cavity. tissue derived from mesoderm partly lines the fluid filled body cavity of these animals. thus, although organs are held in place loosely, they are not as well organized as in a coelomate. all pseudocoelomates are protostomes; however, not all protostomes are pseudocoelomates. an example of a pseudocoelomate is the roundworm. pseudocoelomate animals are also referred to as blastocoelomate.









































acoelomate animals, like flatworms, have no body cavity at all. semi-solid mesodermal tissues between the gut and body wall hold their organs in place.
