Presentation transcript:

Cnidarians Characteristics Invertebrates Stinging cells-Nematocyst Used to capture food Defend themselves Central body cavity

Body Structure Two types Polyp-vase shaped Mouth opens at top Tentacles surround mouth Stays attached to underwater surface

Medusa-Bowl shaped Mouth opens downward Tentacles trail Adapted to swim

Food Acquisition Use stinging cells to capture prey Use tentacles to pull prey into mouth Prey passes into hollow body cavity Digested Expel waste through mouth http://youtu.be/zkF_1r6ll54

Movement Some have muscle like tissue to move Jellyfish swim Hydra summersault Sea Anemone stretch, shrink and bend http://youtu.be/IXtw3eXq7XA

Nerve Net Nerve cells that spread out like a net Help a Cnidarian move Respond to danger Find food

Reproduction Asexually Sexually variety of ways Budding Just pull apart to form two new polyps Rapid increase in population in short time Sexually variety of ways http://youtu.be/MI5cAFsfpx8

Sexual Reproduction http://youtu.be/wsaZ8-I7akg
