Jellyfish are free-swimming, non-aggressive, gelatinous marine animals surrounded by tentacles, but contact could be dangerous. The jellyfish’s tentacles can paralyze a human and manifests itself as cardiac arrest. Serious stings may cause anaphylaxis and hence people stung by jellyfish must get out of the water. Jellyfish are found in every ocean, from the surface to the deep sea. They are abundant in cold and warm ocean water. Jellyfish have roamed the seas for at least 500 million years, making them the oldest multi-organ animal.
