-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

- 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]]> 2021-03-08 19:15:32 UTC https://padlet.com/grothmannan1/pkiyeub9c6aulfod/wish/1284015765 Flatworms characteristics grothmannan1 https://padlet.com/grothmannan1/pkiyeub9c6aulfod/wish/1284026228 -Bilateral symmetry

-Development of sense organs for prey pursuit 

-Has a central nervous system, hermaphroditic (has male and female reproductive organs)

-Can live everywhere: oceans, freshwater, land, inside other organisms

-Has a head and brain, and regeneration able to grow small body pieces into entire worm

-They eat crustaceans, worms, mollusks, and tiny aquatic invertebrates

-They also eat dead and injured animals]]> 2021-03-08 19:17:33 UTC https://padlet.com/grothmannan1/pkiyeub9c6aulfod/wish/1284026228 Similarities of all 3 grothmannan1 https://padlet.com/grothmannan1/pkiyeub9c6aulfod/wish/1284032668 -They each have a type of symmetry

-They are all multicellular

-They can all exist in aquatic environments 

-They are all invertebrates because they do not have back bones

-They are eat and expel waste from the same opening

-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]]> 2021-03-08 19:21:06 UTC https://padlet.com/grothmannan1/pkiyeub9c6aulfod/wish/1284045235 Links grothmannan1 https://padlet.com/grothmannan1/pkiyeub9c6aulfod/wish/1294533717 https://maryvale.padlet.org/gonzalezc/4s3ny79z7ezpc7zw
