|
|
- Also known as [[Metazoa]]
|
|
- A member of the [[Opisthokonta]]

|
- Multicellular
|
|
- Most basal of Metazoa: [[Sponge]]
|
|
- Water enters through the [[ostia]] and exits through the [[osculum]]

|
- [[flagellated chamber]]
|
|

|
|
- Different cell types
|
|
- Outer layer: [[pinacoderm]]
|
|
- Controlling the ostia: [[porocytes]]
|
|
- Controlling the flagella, eating: [[choanocytes]]
|
|
- Transport nutrition: [[amoebocytes]]
