Topics in Animal Kingdom

1

Animal Construction and Basic Body Plans

  • Animals are multicellular eukaryotic heterotrophs that ingest organic matter for energy and raw materials.
  • Animals lack cell walls in their cells.
  • The animal kingdom has over a million species.
2

Coelom, Development, and Segmentation

  • Coelom is a fluid-filled cavity between the gut and outer body wall.
  • Coelom acts as a hydrostatic skeleton, shock absorber, space for organ enlargement, and circulatory medium.
  • Coelom allows body wall and gut to work independently.
3

Phylum Porifera, Coelenterata, and Ctenophora

  • Porifera are pore-bearing sedentary aquatic animals, mainly marine, with cellular level of organisation.
  • Porifera body wall is diploblastic with outer pinacocytes and inner choanocytes, separated by mesenchyme.
  • Porifera body has ostia and osculum, and a canal system for water flow.
4

Platyhelminthes, Nematoda, and Annelida

  • Platyhelminthes are triploblastic, acoelomate, bilaterally symmetrical, dorsoventrally flattened worms.
  • Platyhelminthes show tissue-organ grade of organisation.
  • Platyhelminthes are soft-bodied and unsegmented; segmentation, if present, is pseudo-segmentation.
