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.
Protostomes include animals including Platyhelminthes, Molluscs, Arthropods, Annelids, Nematodes, and many other lower phyla. Among most of the protostomes, the coelom is formed via splitting a solid mass of the embryonic mesoderm; hence, they are called as schizocoelomates.herefore, it could be concluded that animals in the most developed or evolved phyla in the Animal Kingdom are the deuterostomes. When these two phyla are considered, one (Echinodermata) belongs to the group of invertebrates.
