Jellyfish habitats are fictional regions or biomes within an ocean or sea that are inhabited by swarms of floating jellyfish. These fictional areas are often depicted as being tranquil, beautiful, but also potentially dangerous. The jellyfish that are central elements to these areas are often a type of fictional creature, and dazzling displays of bioluminescence are common. The color of these aquatic creatures (calming blues, reds, golden yellows, etc.) strongly influences the tone of the location as does the relative depth of the area below the surface (in the shallows where there is sun or starlight, deep below where there is only darkness, or somewhere in between). The stinging tentacles of the jellyfish may be deadly or damaging, and these regions may be a type of hazardous location.
