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.
Molluscs and annelids also share a eucoelomate body cavity; i,e,. the coelom is completely lined with mesoderm tissue. A major difference between them is that annelids are segmented and have a closed circulatory system whereas molluscs are not segmented and have an open circulatory system.Phylum: Mollusca - [soft body] snails, bivalves, squid and octopi. Molluscs are a diverse group with over 50,000 described species.nnelids are characterized by having elongate, conspicuously segmented body. Unlike the molluscs with their reduced coelom, annelids have a large coelom that is divided by septa between individual segments. Extreme segmentation believed to be an adaptation for burrowing in soil.
