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.
There are also subtypes of coelom: 1  schizocoelom: develops from split in mesoderm found in annelids, arthropods and molluscs. 2  haemocoelom: true coelom reduced & cavity filled with blood found from arthropoda and mollusca. 3  enterocoelom: develops from wall of embryonic gut found from echinodermata to chordata.
