A jellyfish is an aquatic group of animals found in every ocean of
the world. It is soft-bodied and also a free-swimming animal with a
gelatinous umbrella-shaped bell and trailing tentacles.
Jellyfish can also be found in some ponds or freshwater lakes. While most jellyfish species are often found in shallow coastal waters, some species live in the very depths of the oceans. Jellyfish are believed to be the oldest multi-organ animal species in the world dating back to at least 500 million years back and possibly even 700 million years more.
