Jellyfish as food jellyfish, which may utilize salt curing to accomplish this, creating a dried finished product. Some commercially processed edible jellyfish are purveyed in dried sheets. The process of producing dehydrated jellyfish typically includes the removal of the tentacles prior to drying, because the upper dome area of the marine animal is the part typically used for cooking. Jellyfish deteriorate rapidly at room temperature so processing starts soon after they are caught. The bell is separated from the dangling oral arms and both are washed in seawater before being scraped to remove the gonads and mucus. Dehydration is traditionally undertaken by sprinkling
Jellyfish Lake in the afternoon. The moon jellyfish do not have an organized horizontal migration pattern. At night they migrate to the surface presumably to feed. The copepods that make up a significant portion of the moon jellyfish diet in Jellyfish Lake also migrate to the surface at night. Beginning in about the fall of 1998, a precipitous decline in the golden jellyfish medusa population was detected in Jellyfish Lake. By December 1998, the medusa population had declined to zero. Based on their extensive investigation of the disappearance of the golden jellyfish medusae, Dawson et al. determined that the most likely cause
