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.
2. Nearly all annelids have a fluid-filled cavity between the outer body wall and the gut, and this is referred to as a coelom (Figure 1). The coelom is often used as a storage area for gametes and acts as a hydrostatic skeleton for locomotion.he coelom (formed via schizocoely) is generally organized as a series of compartments divided by intersegmental septa. This compartmentalization means that if the worm is damaged the coelomic contents will only be lost from a few segments, and locomotion can be maintained.
