Habitat for others
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.
