- Separating the ostia and the spongocoel
- Different cell types
- Outer layer: pinacoderm
- Controlling the ostia: porocytes
- Controlling the flagella, eating: choanocytes
- Transport nutrition: amoebocytes
- A few taxa of interest with respect to the origin of animals:
- Goes through cleavage-divisions
- Required to be multicellular and go through morphogenesis
