Jellyfish are softbodied, free-swimming oceanic creatures with a coagulated umbrella-formed chime and trailing appendages. Jellyfish are found in each sea, from the surface to the remote ocean. Scyphozoans are only marine, yet a few hydrozoans live in freshwater. Huge, frequently bright, jellyfish are basic in beach front zones around the world. Jellyfish have wandered the oceans for no less than 500 million years, and conceivably 700 million years or all the more, making them the most established multi-organ creature. The ringer can throb to secure drive and headway. The appendages might be used to catch prey or protect against predators by emanating poisons in a difficult sting. Jellyfish species are grouped in the subphylum Medusozoa which makes up a noteworthy piece of the phylum Cnidaria, despite the fact that not all Medusozoa species are thought to be jellyfish.
