Jellyfish

Jellyfish are over 95 percent water and do not have gills, a heart, blood or a brain. Even though their organs are limited, they still retain the sense of taste and smell. Jellyfish cannot see objects, but can sense the difference between dark and light areas. The body of the jellyfish is called the bell, in reference to its shape. Many jellyfish also have stinging tentacles which can span over 100 feet in length. These tentacles are used to sting and capture prey. Jellyfish feed mainly on small animals called zooplankton.
