Question

What are the coelom present in phylum?

Answer 1

The organisms of phylum Annelida have a true body cavity called coelom . Coelomate animals or Coelomata (also known as eucoelomates — "true coelom") have a body cavity called a coelom /ˈsiːləm/ with a complete lining called peritoneum derived from mesoderm (one of the three primary tissue layers).
