From the lighter side: Entertaining!
But seriously, folks: Jellyfish are free-swimming members of the phylum Cnidaria. They can be found in every ocean and can float around near the surface or deep under. If you touch a jellyfish's tentacles (the stringy parts that flow from the rounded part), you'll get stung and it's going to be pretty nasty. There are quite a few species of jellyfish, but the scyphomedusae are the most well known. Those are the large jellyfish that are common coastal areas worldwide. Jellyfish are mostly transparent or translucent, though some may be colorful. They are carnivorous (they eat meat) and live all around the world.
bigger animals are the jellyfishes enemies.
