Animals that have true coelom are called Eucoelomates such as phylum Annelida, Arthropoda, Mollusca, Echinodermata, Hemichordata and Chordata. The fluid filled body cavity is lined with peritoneum, which is derived by embryonic mesoderm, and separates the digestive tract and outer body cell wall.
Animals without it, such as flatworms, are called acoelomates. In between there are some animals called pseudocoelomates, which possess a false coelom, which is an unlined or partially lined body cavity between the gut and body wall. A coelom is defined as a cavity that separates the gut from the body wall.It allows the internal organs to shift around and develop independently of the body wall, creating more physiological and evolutionary flexibility.SouthernMuse-The difference between pseudo coeloms and true coeloms is that a true coelom has a mesodermal lining on all sides, allowing muscles to develop that surround the organs and support them within the body wall.
