Microbiology of Sponges
3 layers: central jelly layer surrounded on either side by live cells.
No nervous system
Jelly layer is non-living, but contains a variety of other cells.
Outer cell layer is made of pinaccocytes, forms external skin.
Inner cell layer is made of Choanocytes, which regulate water flow
Porocytes filter water through jelly layer.
Archaeocytes are totipotent (can transform into any other type of cell in the body), useful for regeneration, reproduction, hazard removal, transport, and a variety of other tasks.
