1. Megan Finnerty Biology 5/6

2. CCnidarians ◦J◦Jellyfish ◦H◦Hydra ◦S◦Sea Anemones ◦C◦Coral PPorifera ◦S◦Sponges

3. SSymmetrical MMulticellular, few tissues, some organelles CContains internal cavity and a mouth NNet like nervous system AAquatic environments MMinimal skeleton, of chifton or calcium carbonate

4. NNo definite symmetry. BBody multicultural, few tissues, no organs. HHas no nervous system. LLives in aquatic areas. AAll are filter feeders. OOften have skeleton of spicules.

5. Paralyzes prey with tentacles and then the food falls into the mouth. It is then digested in the gastrovascular cavity Cnidarians Feeding http://universe-review.ca/R10-33-anatomy.htm

6. Takes the Incoming water and filters it. Food particles are then trapped by the choanocytes. Food is digested and then passed along to the archaeocyte cells. Porifera Feeding http://www.biologie.uni-hamburg.de/b-online/library/onlinebio/BioBookDiversity_7.html

7. CCnidarians ◦F◦Following the digestion, nutrients are transported by diffusion. ◦W◦Waste is through the body walls by diffusion. PPorifera ◦A◦As the water moves through the body cavity, oxygen is dissolved. ◦W◦Waste is diffused.

8. Uses the nerve net to detect stimuli Cnidarians Response http://biodidac.bio.uottawa.ca/thumbnails/catquery.htm?Kingdom=Animalia&Phylum=Cnidaria&category=diagbw

9. No nervous system Can produce toxins instead Porifera Response http://mymarinebiologyhome.blogspot.com/2007/09/shape-of-life-090807.html

10. UUses water in the gastrovascular cavity and hydrostatic skeleton UUses jet propulsion to move http://funscubadiver.com/gallery/bonaire-giant-sea-anemone.htmhttp://lifestyle.iloveindia.com/lounge/jellyfish-facts-5755.html O R

11. AAre Sessile (live adult life stationary) AAs a larva, it is carried by water currents until stationary larva http://www.biology.ualberta.ca/CMD/home.htm

12. Both Sexually and Asexually reproduction Polyps can either reproduce asexually by budding and creating another polyp or producing a medusa The Medusa(male) releases the sperm in open water and fertilizes the egg Cnidarians Reproduction http://universe-review.ca/R10-33-anatomy.htm

13. Both sexual and asexual reproduction Sperm released into water currents, brought to female for internal fertilization Asexual is by budding or gemmules Porifera Reproduction http://authors.ck12.org/wiki/index.php/Simple_Invertebrates:_Sponges,_Cnidarians,_and_Worms

14. BBoth are invertebrate BBoth are protostomes PPoriferia have no symmetry while Cnidarians have radial symmetry
