-Poriferans have a spongy appearance

-Can withhold fluids. they are multicellular with no organs or tissues

-Eat by filter feeding and are asymmetric

-They eat tiny floating organic particles and plankton

# data[].attributes.body
-They each have a different type of symmetry

-The poriferans are filter feeders

-The poriferans have external fertilization and reproduce sexually and asexually

-Both poriferans and cnidarians produce toxins as a defense mechanism

-Flatworms nervous system is located in their head

-Cnidarians use jet propulsion to move forward

- Cnidarians have 2 body forms with 3 layers: polyp: sessile form, oral surface up, tentacles up; medusa- swimming form, oral surface down, tentacles floating down; radially symmetrical

-Cnidarians use highly specialized stinging cells to capture prey and for protection

-They eat starfish, sea slugs, fish, turtles, other cnidarians, and dinoflagellates
