2. General Description
A phylum of aquatic invertebrate animals that comprises the sponges
Multicellular, porous bodies that allow water to flow through

3. Symmetry
Most commonly asymmetrical
Some can exhibit radial symmetry

4. Feeding Filter feeders Water enters through ostia (small pores)
Once food is filtered out, water exits through osculum (large pores)
carnivorous

5. Circulation No circulation system
Depend on water flow to feed, get oxygen, and remove waste
Adapted body shape to maximize water flow

6. Excretion cells release their waste products
 Water flows through and filters out the waste products
They all have different shapes

7. Response Multicellular organisms,
No organs, no brain, no nervous system.
can respond to an external stimuli is through their physical structures

8. Movement
Sessile
They cannot move at all

9. Asexual reproduction achieved through budding
male sponge releases sperm into the water to enter a female sponge in sexual reproduction

10. Respiration
 oxygen moves from water to sponge through diffusion

11. Class
