Range from 2 to 40 centimeters; some can reach up to 2 meters in diameter. Largely water (94% to 96%) with thick jelly layers. Radially symmetric.
|General information: |
Jelly fish begin as polyps with tentacles and look like an anemone. As adults they have a body-form called a medusa. It is a bell-shapewith trailing tentacles. The jellyfish swims by contracting and relaxingmuscles around the edge of the bell.
|Special anatomical, physiological orbehavioral adaptations: |
The radial symmetry in the jellyfish allows the ability to sense bothfood and possible danger on all sides. This is beneficial becausethe jellyfish is not a fast swimmer. The tentacles of the jellyfishbear cnidocytes or stinging cells. These are used for defense andalso to capture food.

|Personal Observations: |
The jellyfish is very graceful as it pushes itself through the water.The Monterrey Bay Aquarium has a very large display of jellyfish with ablue background. This gives the jellyfish the appearance of glowingin the dark.
