How do you care for Atolla Jellyfish (Deep-sea Crown Jelly)?
| Light | Lives in total darkness; light is foreign to its habitat. It makes its own blue flashes when attacked. |

How do you trim and propagate Atolla Jellyfish (Deep-sea Crown Jelly)?
Not applicable: no home maintenance exists. In the wild it eats plankton, including gelatinous zooplankton and small crustaceans, caught with one long tentacle. It reproduces sexually (the tentacle is used in mating, per Wikipedia) and asexually via polyps; life-cycle details were not verified.
What problems affect Atolla Jellyfish (Deep-sea Crown Jelly)?
The problem is not husbandry but that it cannot be kept: it needs a cold, dark deep-sea environment and can only be collected by remotely operated vehicle (ROV) from hundreds to thousands of metres.
How do you fix Atolla Jellyfish (Deep-sea Crown Jelly) problems?
Enjoy it through wild footage or at a public aquarium that keeps deep-sea jellies; Monterey Bay Aquarium shows a red crown jelly in its Midwater exhibit. No temperature, oxygen or survival-time figures were verified, so none are given.

Deep ocean worldwide; the genus occurs in all oceans. Lives in the midnight (bathypelagic) zone, open water, below sunlight, about 1,000-4,000 m for A. wyvillei (genus roughly 500-5,000 m).
What should you know before buying Atolla Jellyfish (Deep-sea Crown Jelly)?
No sting hazard is documented in the sources consulted. It cannot survive outside a cold, dark deep-sea set-up, and removing it from the wild needs deep-sea research capability. Its red looks black at depth; when attacked it throws pinwheels of blue flashes, a 'burglar alarm' that draws bigger predators.
