CnidariaThe beautiful wonders of the ocean By: Simon Han
Why should you date me? • I have cnidocytes (venomous cells) that I can use to protect you. • I’m radially symmetrical. Symmetry = Beauty • I have no central nervous system or respiratory organs. Less worries. • I’m very relaxed. I go with the flow, but it’s not because I’m too weak to swim against currents.
Where can I be found? • I live in aquatic environments, mainly marine environments, and I can be found from coral reefs to arctic oceans. • All I require is water and zooplankton to feed on.
What are my favorite activities? • Provide the world’s most beautiful and productive ecosystems. (Coral reefs) • Sting things that get caught in my tentacles. • Deliberately injure myself and regenerate.
What are my evolutionary advancements? • Multicellularity • Two germ layers (Diploblasts) • Nerve cells (A nerve net for nervous system) • Radial symmetry
What are some of my unique features? • Cnidocytes, the venomous cells on my tentacles • A middle layer of jelly called the mesoglea between the two germ layers • Use of the cavity has a hydrostatic skeleton • Regeneration
What am I looking for? • Cnidarians only, but any class works • Must be patient (I have a very complex sexual reproductive cycle)
