Traditional processing methods, carried out by a jellyfish master, involve a 20- to 40-day multi-phase procedure in which, after removing the gonads and mucous membranes, the umbrella and oral arms are treated with a mixture of table salt and alum, and compressed. Processing makes the jellyfish drier and more acidic, producing a crisp texture.
Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a species of the family Ulmaridae.

Deepstaria enigmatica have been observed during jelly-falls. This happens when a jellyfish carcass falls through the water column to the ocean floor. A Deepstaria enigmatica jelly fall was first observed in the lower portion of the oxygen minimum zone of the ocean. It was observed as shrimp and crabs were scavenging its carcass.
Box jellyfish swim by expanding and contracting their bells vigorously. [6] During the day Tripedalia cystophora is mostly to be found within 20 cm (8 in) of the surface, in sunlit positions among the prop roots of mangroves. These warm sunlit areas are where its main food item, the copepod Dioithona oculata, are to be found during the day. [5]
