Circulatory System
Diffusion
Unique Characteristic
Stinging cells: cnidocytes
Tentacles
Importance

Habitat for others

11. Coelm: body cavity Fluid filled space in multicellular animals
Coelomate animals: true cavity: with a complete lining called peritoneum derived from mesoderm
Pseudocoelomate animals have a pseudocoel:
“false cavity”
tissue derived from mesoderm only partly lines the fluid filled body cavity of these animals.
All pseudocoelomates are protosomes
Acoelomate animals, like flatworms, have no body cavity at all. Organs have direct contact with the epithelium.
