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 circular tanks to avoid trapping specimens in corners. They have a live "Jelly Cam". The outflow is spread out over a large surface area and the inflow enters as a sheet of water in front of the outflow, so the jellyfish do not get sucked into it. As of 2009, jellyfish were becoming popular in home aquariums, where they require similar equipment. Jellyfish are armed with nematocysts. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom, but only some species' venom causes an adverse reaction in humans.
