Answer 1

Coelomate animals have a coelom, this is a body cavity that has a mesodermal lining. Coeloms arise in two different ways. Through splitting of the mesoderm cell mass which arises from the walls of the archenteron in which case it is called a schizocoelom. Or from the invagination of parts of the endodermal aspect of the archenteron, when it is called an enterocoelom. The coelomate phyla are Entoprocta, Ectoprocta, Phoronida, Brachiopoda , Mollusca, Priapulida, Sipuncula , Echiura, Annelida, Tardigrada, Pentastoma, Onychophora, Arthropoda, Pogonophora, Echinodermata, Chaetognatha, Hemichordata, Chordata.
