Bibcode: 2004LimOc..49..233A. doi: 10.4319/lo.2004.49.1.0233. At least 10 jellyfish collectively can carry SpongeBob into the sky. SpongeBob, in particular, is extremely fond of the creatures and never tries to intentionally hurt them. Likewise, most jellyfish see SpongeBob as a friend as they comforted him when his dreams of flying were crushed and later called on his aid to stop the construction of a highway that had gone through Jellyfish Fields.

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. Jellyfish prepared this way retain 7–10% of their original weight, and the processed product consists of approximately 94% water and 6% protein. Freshly processed jellyfish has a white, creamy color and turns yellow or brown during prolonged storage. [126]The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5m (119ft 9in) long (though most are nowhere near that large). [54] [55] They have a moderately painful, but rarely fatal, sting. [56] a b c Angier, Natalie (6 June 2011). "So Much More Than Plasma and Poison". The New York Times.

Green jellyfish - A very rare kind of jellyfish that is green with an amazing height-bearing flight that makes them pretty high from defeat. In Revenge of the Flying Dutchman and the DS version of SpongeBob's Atlantis SquarePantis, they are seen on many levels, including the Bikini Bottom main hub, Jellyfish Fields, the Volcano of Mu and the underground cave of the Amulet.

[ permanent dead link]Big Lenny - An enormous and dangerous jellyfish whose stings are almost always fatal. The only person known to have survived one is named Dr. Manowar, who has a gigantic swelling on the side of his head as a result. This swelling only hurts when someone touches it. Big Lenny could be a Man O' War or a box jellyfish as their stings are known to kill people. Big Lenny is seen in " I'm Your Biggest Fanatic" as a picture and in the PC game Operation Krabby Patty during the jellyfishing game. This article is about the aquatic animal-form. For similar animals, see gelatinous zooplankton. For other uses, see Jellyfish (disambiguation).

League, Michael (11 October 2011). "The Way to End a Dive". PolarTREC. McMurdo Station, Antarctica. Further information: Bioluminescence and Green fluorescent protein The hydromedusa Aequorea victoria was the source of green fluorescent protein, studied for its role in bioluminescence and later for use as a marker in genetic engineering. Most jellyfish do not have specialized systems for osmoregulation, respiration and circulation, and do not have a central nervous system. Nematocysts, which deliver the sting, are located mostly on the tentacles; true jellyfish also have them around the mouth and stomach. [33] Jellyfish do not need a respiratory system because sufficient oxygen diffuses through the epidermis. They have limited control over their movement, but can navigate with the pulsations of the bell-like body; some species are active swimmers most of the time, while others largely drift.

S2CID 10927442. Archived (PDF) from the original on 3 March 2016.In 1961, Osamu Shimomura extracted green fluorescent protein (GFP) and another bioluminescent protein, called aequorin, from the large and abundant hydromedusa Aequorea victoria, while studying photoproteins that cause bioluminescence in this species. [134] Three decades later, Douglas Prasher sequenced and cloned the gene for GFP. [135] Martin Chalfie figured out how to use GFP as a fluorescent marker of genes inserted into other cells or organisms. [136] Roger Tsien later chemically manipulated GFP to produce other fluorescent colors to use as markers. In 2008, Shimomura, Chalfie and Tsien won the Nobel Prize in Chemistry for their work with GFP. [134]

Ryall, Julian (2 November 2009). "Japanese fishing trawler sunk by giant jellyfish". London: Telegraph.co.uk. Archived from the original on 4 November 2009. Jellyfish play an essential role in the ocean’s food chain. They consume a variety of smaller organisms, including microscopic plankton, various crustaceans, and even other jellyfish.
