Nervous System
Moon Jellyfish lack basic sensory organs and a brain. Their nervous system and rhopalia
(a small sensory nerve that most Scyphozoa have) allow them to perceive stimuli, such as light, odor and allows them to respond quickly. The jellyfish has a series of interconnected nerve cells called a nerve net. Some jellyfish have specialized structures called rhopalia. They have receptors for light, balance, chemical detection and touch.
