Jellyfish swim in an unusual way, with a pumping action. Muscles in their bodies contract and propel them through the water.
A jellyfish takes food in through its mouth which is located on the underside of its bell. Food is digested in a sac-like structure, and the waste is passed out through the mouth.
The long tentacles of the jellyfish are what produce the sting. You can touch the top of the jellyfish without being hurt.
Jellyfish come in white, blue, pink, yellow, green, purple, red and orange colors.
