  10. 10. Nervous System<br />it characterized by a series of interconnected nerve cells (a nerve net). <br />The nerve net conducts impulses around the entire body of the jellyfish.<br />http://i62.photobucket.com/albums/h118/jessjoy81/Jellyfish.jpg<br />
  11. 11. Nervous System cont.<br />The strength of a behavioral response is proportional to the stimulus strength. <br /><ul><li>Nervous system work when jellyfish receptors for</li></ul>1.

  12. 12. Reproduction<br />The eggs and sperms developed inside the body wall called “ Gonads”<br />After eggs are fully developed then release into stomach then through the mouth into the sea. <br />In most case, male jellyfish releases his sperms into the surrounding water. then the sperms swims into female jellyfish’s mouth—the fertilization occur. <br />http://i66.photobucket.com/albums/h254/kristin77_photos/jellyfish.jpg<br />
  13. 13. Reproduction<br />The egg is released into the water and it becomes a larvae.<br />The larvae attaches itself to a base and it becomes a polyp (which looks like an anemone) <br />It develops more and it will create and release the baby jellyfish<br />One larvae can produce +5 jellyfish <br />http://i62.photobucket.com/albums/h118/jessjoy81/Jellyfish.jpg<br />
