20	The symbol of a serpent [[{{Autocannibalism}} eating its own tail]], making a circle.
21
22	Dating back to AncientEgypt, the Ouroboros is a symbol of [[{{Infinite}} eternity]] and the cyclical nature of time and the universe. The fact that the serpent is eating itself is also indicative of the idea of self-consumption in the way we live. Sometimes it may even be two serpents each eating the other's tail, taking on similarities with the [[DragonsUpTheYinYang Yin Yang]] symbol. Another, [[NewerThanTheyThink more modern]] common variation is for the snake or snakes to have an additional knot which forms the infinity symbol, ∞.
23
24	The ouroboros' primary {{Motif\|s}}, found in ancient and medieval philosophical and UsefulNotes/{{alchem\|y}}ical texts, is a representation of eternity and cycles. In particular, it is associated with themes of death, rebirth, and renewal and with interpretations of history as a repeating cycle instead of a linear progression. In modern fiction, it is also often associated with TimeTravel, and in particular with the concept of time loops, where the "final" parts of the sequence serve to set up the "starting" ones in a cycle with no beginning or end. Note the connection to ThePhoenix and also the serpent as the shedder of skin and rejuvenator which acts much like the phoenix motif.
25
26	Sometimes, the ouroboros is present as a physical being in its own right, and, in some versions, the serpent encircles the world or the WorldTree, and is tied to its fate. Most often, however, the ouroboros appears as a symbol or motif instead of a living creature.

38	* ''Manga/BattleAngelAlita'': [[BigBad Desty Nova]] has a LotusEaterMachine he has named the Ouroboros program.
39	* ''Manga/FullmetalAlchemist'': All of the homunculi are marked for what they are by a tattoo of a winged serpent eating its tail with a hexagram in the center, somewhere on their bodies. Also interesting, is that "One is all, all is one" is sort of ArcWords for the series.
40	%%* ''Literature/HighSchoolDXD'' gives us Orphis, the [[PhysicalGod God of Dragons]].
41	* ''Manga/KenichiTheMightiestDisciple'': The Eight Deadly Fists of Ragnarok have Ouroboros surrounding the Roman Numerals on their gloves.

43	* ''Anime/MonColleKnights'': Oroboros is the master of the seventh realm, time, and as such it is an inorganic lifeform. It "appears" through the center of a gate that is the mathematical infinity symbol, and the Big Bad intends to use it to make everything one.
44	* ''Anime/{{Noein}}'': This motif crops up a lot, usually signaling that the amount of crazy quantum time travel hax is about to get even ''worse''. The giant one that occasionally appears by a nearby island even [[spoiler:serves as a portal to (effectively) TheLegionsOfHell]] near the end of the series.
45	* ''Manga/{{Ouroboros}}'': The two main characters are in a team named Ouroboros, whose symbol is two dragons that bite each others' tails to form an infinity sign. This can also be found in one of Tatsuma's one-liners: "There are two dragons in Ouroboros".
46	* ''Anime/TigerAndBunny'': A crime syndicate calls itself Ouroboros; members can be identified by ouroboros-symbol tattoos. For a while, Barnaby believed they were [[spoiler: responsible for his parents' deaths, but they turned out to be a {{red herring}}]]. While it seems like it is unrelated to the motif of the Ouroboros, Ouroboros is in fact [[spoiler:fed by Maverick, who essentially leads the heroes. His actions cause Ouroboros to become a real shadowy organization as well, and they are essentially unstoppable, vowing to return [[SequelHook at the end of the series.]]]]
47	* ''Manga/SoutenKouro'', an adaptation of ''Literature/RomanceOfTheThreeKingdoms'' [[RootingForTheEmpire focusing on Cao Cao]], starts with depiction of the ''Ton'', a massive grotesque snake/dragon/crocodile-like beast that eats the world.

As long as her tail remains in her mouth, the world is held in balance. When she gets possessed by the [[EldritchAbomination Lord of the Locusts]], she lets go of her tail and the world is no longer safe.
53	* ''ComicBook/GIJoeDevilsDue'': In the ''G.I. Joe Reloaded'' AlternateContinuity, an ouroboros is the symbol Cobra carved in the place of one of their first attacks.
54	* ''ComicBook/MickeyMouseComicUniverse'': In "The Dragon That Swallows Its Tail", the protagonists, during their journey, end up going to the past, and find the eponymous dragon, which is actually a cave formation. At its end turns out to be a portal to the modern day; they cross through and find out that their arrival caused a StableTimeLoop which made them go on their journey in the first place.
55	* ''ComicBook/{{Thorgal}}'': In "The Lord of the Mountains", a ring that allows time travel takes the form of an Ouroboros. It happens to represent the StableTimeLoop that will happen/has happened to one of the characters.

59	[[folder:Fan Works]]
60	* ''[[https://www.fimfiction.net/story/7335/apotheosis Apotheosis]]'': Much like Celestia and Luna embody the sun and moon, the two dragon gods represent the ouroboros. In the physical world, this is symbolically represented through a cyclical pattern of usurpation and renewal -- one brother rules for a time, but over time becomes corrupt and complacent; this drives the other to usurp him, bring initiative and leadership back to the dragons, and banishes the former ruler into the wilderness, where he broods and renews himself until it is time to repeat the cycle. In the spirit world, the two are represented by a physical ouroboros, a reclusive beast that embodies the brothers and their endless cycle.
61	* ''Fanfic/PastSins'': In ''The Road Home'', Shining Armor, Cadence, and Twilight are attacked by a lake serpent with AHeadAtEachEnd that Twilight identifies as an ouroboros.

65	[[folder:Film -- Animated]]
66	* ''WesternAnimation/TheSecretOfKells'': Brendan manages to defeat [[EldritchAbomination Crom Cruach]], an ancient deity which resembles a mix between using a gigantic serpent and a Celtic Knot, by [[ArtInitiatesLife trapping him within a chalk circle]] and stealing his eye, whereupon Crom, blinded, consumes himself into nothingness.

70	* ''Film/TheFerryman'' involves an evil spirit that manages to escape death by possessing the bodies of the people on board a pleasure cruise.

73	[[folder:Literature]]
74	* "Literature/AllYouZombies": The bartender wears an ouroboros ring, symbolizing how the story's event make up a convoluted, self-contained StableTimeLoop, and how [[spoiler:the main character's history is a closed looping system, as through time travel he's fated to have a one-night stand with himself to give birth to also himself, and then to go back again and make sure that the whole thing takes place properly]].
75	* ''The Chrysopoeaia of Cleopatra'' is an alchemical text that dates all the way back to 2nd century Alexandria. "Chrysopoeaia" means rather literally "Making Gold" or basically, since you're dealing with alchemists here, transmutation into gold i.e. a Philosopher's Stone. You can also see from the light-dark comparisons the similarity to the [[DragonsUpTheYinYang Taijitu]].
76	* ''Franchise/ConanTheBarbarian'': In ''Literature/ThePhoenixOnTheSword'', Thoth-amon's Ring of Power is shaped like a serpent coiled three times and holding its tail in its mouth.

78	* ''Literature/{{Discworld}}'':
79	** ''Literature/TheLightFantastic'': Tethys, the water troll, landed on the Disc after falling off another world. One of the worlds he passed had a giant serpent eating its own tail around the disc, instead of the turtle/elephant arrangement of ''Discworld'' itself. This may be a reference or either the Norse mythology of Jörmungandr or, due to it also appearing in connection to the turtles-elephants-world model, Adisesha of Hindu tradition.
80	** ''Literature/{{Pyramids}}'': Dios carries [[SerpentStaff a staff tipped with a pair of carved serpents]]. He doesn't actually notice that each one has its tail in its mouth until after [[spoiler: he's flung 7000 years into the past, making him a StableTimeLoop.]]

83	* ''Literature/{{Redwork}}'' is about alchemy, and there's a ring in the shape of a serpent eating its own tail.
84	%%* ''Literature/SeptimusHeap'': Septimus's Dragon Ring is an Ouroboros.

89	* ''Literature/WorldWithoutEnd'' has it, not in the narrative itself, but rather in the cover (actually, it looks more like a basilisk).
90	* ''Literature/TheWormOuroboros'' is a story that is taken to be part of a wider conflict with an ill-defined beginning or end which casts an interesting light on the heroics of the main characters. To reflect this, they have the name and also the BookEnds of HereWeGoAgain.
91	%%* ''Literature/{{Wyrm}}'': The ouroboros is an important recurring symbol.%%How?
92	[[/folder]]

94	[[folder:Live-Action TV]]

99	* ''Series/TheHeartSheHoller'': [[RealityWarper Meemaw]] creates a RecursiveReality by telling a story to Hambrosia about herself telling a story to Hambrosia. In the appropriately-titled [[WhamEpisode "Oralboros"]] Cutter the Vet dies from a VisualPun the full effects of this RecursiveReality when he makes an Ouroboros out of himself.

101	* ''Series/{{Lost}}'': In Mrs. Hawking's first appearance, she is wearing a brooch in the shape of an ouroboros. Appropriately enough, her role is to tell Desmond [[MentalTimeTravel (who is in the past, but with memories of his future)]], [[YouCantFightFate to not deviate from the timeline he remembers]]. In Season Six, when Desmond meets her, she's wearing a different brooch that [[AlternateUniverse has two parallel lines on it]].
102	* ''Series/Millennium1996'': Members of the Millennium group are identified by the Ouroboros symbol.
103	* ''Series/ThePretender'': This is the symbol of a sect that practices cannibalism. Later, it's revealed that [[spoiler:Mr. Lyle]] is a member.
104	* ''Series/RedDwarf'': "[[Recap/RedDwarfSeasonVIIOuroboros Ouroboros]]" reveals that Lister was discovered as a DoorstopBaby in a box with the word "Ouroboros" on it (originally misread as "Our Rob or Ross"). This turns out to be significant as [[spoiler:Lister is [[MyOwnGrampa his own father]]]]. The box originally contained Ouroboros-brand everlasting batteries.
105	* ''Series/TheXFiles'': In "[[Recap/TheXFilesS04E13NeverAgain Never Again]]", Scully got an Ouroboros tattoo. Then she [[DidTheyOrDidntThey did or did not]] hook up with a guy with [[AnimatedTattoo a tattoo that talked to him]]. It's one of several hints from the series that Scully might be somehow immortal.

113	* Music/TheMarsVolta: ''The Bedlam in Goliath'', the fourth full-length album, contains a track named "Ouroborous" that loops back onto a pair of choruses and a series of guitar riffs that WordOfGod has declared to be a reference to this motif. Also fits in with the various weirdness that permeates the album, being as it is based around sayings and events that the band encountered while using an old OuijaBoard they found in UsefulNotes/{{Jerusalem}}, and the string of unpleasant events that they thought were due to a curse from the board.
114	* Music/{{Mothy}}: In the Music/{{Vocaloid}} song "The Escape of Salmhofer the Witch" in the ''Music/EvilliousChronicles'', two ouroboros symbols are seen at the end, probably representing the "Twin Gods" of the series.
115	* Music/TheSmashingPumpkins' fifth album ''Machina'' featured a lot of artwork from Vasily Kafanov and a lot of other alchemy-inspired artwork.

116	* Music/TaylorSwift: The lyric video for "Look What You Made Me Do" features an ouroboros during the chorus.

124	* Myth/HinduMythology: Adisesha is a [[OurTitansAreDifferent primordial being]] who coils and forms the seat of Vishnu. Adisesha does not actually consume itself and it in fact has thousands of heads but still Adisesha forms a symbol for infiniteness and the endlessness of time.
125	* Hoop snakes, which are part of folklore in both [[FearsomeCritters North America]] and [[YowiesAndBunyipsAndDropBearsOhMy Australia]] supposedly bite their tail and roll downhill to escape danger. (There aren't any snakes that actually do this.)
126	* Myth/NorseMythology: Jörmungandr, the World Serpent, is the offspring of the giantess Angrboða and [[TricksterGod Loki]] who grew so large that he could encircle Midgard, the Earth, and grasp his own tail. When Jörmungandr lets go of his own tail, the world will end.
127	* Literature/TheTalmud:
128	** Bava Kamma 117a-b describes an event where Rav Kahana died, and a huge serpent encircled the hill where he was buried with its tail in its mouth. Rabbi Yochanan, who [[WhatHaveIDone felt responsible for his death]], had to ask three times before the serpent would let him pass, the final time referring to Rav Kahana as his "teacher" instead of his student or colleague. [[BackFromTheDead Then he raised him from the dead]].
129	** A similar story is told about Rabbi Elazar son of Rabbi Shimon (Bava Metzia 84b). The other rabbis didn't bother to bury him for many years. Eventually, Rabbi Elazar's father appeared to them in a dream and demanded why his son wasn't buried beside him. In this case, the snake let them in when they called "Serpent, serpent! Open your mouth to allow a son to enter next to his father." A serpent also encircled the cave when Rabbi Elazar's own son was was going to be buried, but apparently couldn't be dislodged (85a).

138	* ''TabletopGame/{{Pathfinder}}'':
139	** Stats for the ouroboros are included in ''Bestiary 6''. They are described as being enormous serpents [[TheWormThatWalks made from even tinier serpents (in turn made from even smaller ones, repeating to infinity)]] from the Astral Plane. Embodiments of the cycle of creation and destruction, they forever consume themselves and are reborn in an endless loop. They are among the most powerful beings in the cosmos, but are extremely aggressive and destructive, making them a favorite summon for extremely powerful but homicidally insane spellcasters.

146	** ''TabletopGame/WerewolfTheApocalypse'': ''Chronicles of the Black Labyrinth'' discusses the Ouroboros as a symbol of the Wyrm.

150	* ''Franchise/BlazBlue'': Hazama has a weapon called Ouroboros which grants him long-range attack options.

155	* ''VideoGame/BroodStar'': The Ouroborosect is a dragon-like space bug whose serpentine body encloses the playable area of the screen during its boss fight. It doesn't bite its own tail because it's too busy spitting energy bullets and laser beams at the player's spacecraft.

157	* ''VideoGame/CityOfHeroes'' has an organization called Ouroboros that seeks to fix problems caused by people messing with time. In game terms, their facilities allow players to replay story arcs they have outleveled. Their symbol is a golden, angular ∞ version.

160	* ''VideoGame/FalloutNewVegas'': In the DLC ''Old World Blues,'' all the [[BrainInAJar Think Tanks]] have looping thought processes as a result of a limitation of their programming.

161	* ''VideoGame/FireEmblemHeroes'' depicts Gullveig, the BigBad of Book VII, with a SnakesAreSinister motif, which is eventually revealed to be additionally based on the mythological Ouroboros.

The Chapter where this reveal is dropped is also literally titled “Ouroboros”.
162	--> '''Gullveig''': “All those born of the past will know death in the future. I, however, was not born—and neither will I ever meet my end. My life is a cycle unending, eternal. The golden serpent springs ever forth from its own swallowing mouth.”
163	* ''VideoGame/FlightRising'': Mentioned by the description of the Swallowtail Buttersnake familiar (as a pun on the more literal definition of swallowtail), "Also known as the Ouroboros Buttersnake."

165	* ''VideoGame/GrooveCoaster'': The track "ouroboros -twin stroke of the end-" features one in its background visuals. Furthermore, [[BookEnds the intro of the track is repeated at the end]], and yes, [[https://www.youtube.com/watch?v=GqCcy_P9XGE&t=312s fans have looped it.]]

172	* ''VideoGame/MegaManZXAdvent'': The Ouroboros is [[spoiler:the ultimate [[TransformationTrinket Biometal]] in the form of a giant floating ring made up of all the [[ArtifactOfDoom Model Ws]], which serves as the final level of the game and the source of the BigBad's final OneWingedAngel, through which he intends to RestartTheWorld]].
173	* ''VideoGame/MetalGearSolid2SonsOfLiberty'' has an Ouroboros appear in the map screen if you try to use it when GW is glitching. This hints at the purpose of the S3 program.
174	* ''VideoGame/NoMoreHeroes'': The last boss fight takes place in an arena surrounded by an energy dragon that eats its own tail. It constricts more tightly as the battle progresses, representing the self-destructive cycle of revenge.
175	%%* ''VideoGame/{{Peggle}}'': ''Peggle Nights'' has an Ouroboros-themed level.
176	* ''VideoGame/ResidentEvil5'': The apocalyptic [[TheVirus Virus]] threat is named "Uroboros" (the Serbo-Croatian spelling), since it [[BodyHorror mutates its host into a giant mass of intertwining tentacles, slowly devouring the host so it must constantly seek more hosts to infect.]]
177	* ''VideoGame/ShinMegamiTenseiStrangeJourney'': The boss of Sector Eridanus is Ouroboros. You have to fight her twice over because, for the first time, five demons are giving her energy to survive indefinitely. She's beaten on the second try, [[ThatOneBoss but who said that it'll be easy?]] [[spoiler: Then it turns out that defeating Ouroboros doesn't actually enable the Red Sprite to escape the Schwartzwelt...]] she appears as a silver serpent, her body in a vertical infinity symbol, tail in her mouth.
178	* ''VideoGame/{{Snake}}'' (yes, that game) pulls a lethally straight example in which snakes die when biting their own tails, much like the real-life example noted below.
179	* In ''VideoGame/Splatoon3'', there is a gigantic, [[SlipperyAsAnEel eel-like]] {{flying\|SeafoodSpecial}} [[{{Superboss}} King Salmonid]] named [[NamesToRunAwayFromReallyFast Horrorboros]]. While it never ''does'' eat its own tail, it always flies in a circle around the stage, and its being named after the ouroboros ties in well with [[TheHorde the Salmonids]]' worship of both [[ToServeMan eating other sapient races]] and [[LetsMeetTheMeat being eaten themselves]].
180	* ''VideoGame/StriderArcade'': The first boss is called Ouroboros, a large centipede/serpent robot created by the merge of Kazakh's ruling party. In its second appearance during the final stage, it actually starts circling itself in place, making it look just like the symbol it is based on. Ouroboros Mk.III from the [[VideoGame/Strider2014 2014 ''Strider'']] is a ShoutOut to it. Ouroboros also just happens to be Hiryu's best-known Hyper Combo from ''VideoGame/MarvelVsCapcom'', though it was likely named due to the Hyper's nature (two bots constantly spinning around Hiryu) rather than as a callback to the boss.
181	* ''VideoGame/SwarmSimulatorEvolution'': The final and most powerful production unit is called the Endless, and it resembles a cosmic ouroboros made of [[AscendToAHigherPlaneOfExistence ascended swarm units]].
182	* ''VideoGame/AVeryLongRopeToTheTopOfTheSky'': Rings that protect against multiple status effects are named after snakes; the best one is the Ouroboros Ring, which stops every status effect except instant death and stun, created by fusing the two Snake Rings, Jade and Yellow.
183	* ''VideoGame/XenobladeChronicles3'': the six main characters gain a power early on that allows them to merge with each other into "Ouroboros forms", represented by a fiery image of an Ouroboros symbol in their eyes. Several characters say that "the will of Ouroboros" is the only thing that can fix the world. [[spoiler:There have been multiple generations of Ouroboros across thousands of years fighting against Moebius, trying to break the stasis Moebius has kept the world trapped in. An eternal cycle created to combat another eternal cycle.]]
184	* ''VideoGame/{{Xenogears}}'': The FinalBoss is [[spoiler:a form of [[BigBad Miang]]]] called Ouroboros, and its defeat probably represents the end of [[spoiler:the 10000-year cycle of death and rebirth [[GreaterScopeVillain Deus]] initiated in order to repair itself and fly off to destroy other planets]].

187	[[folder:Webcomics]]
188	* ''Webcomic/GunnerkriggCourt'': In the [[http://www.gunnerkrigg.com/archive_page.php?comicID=558 third treatise,]] there's an ouroboros symbol in the sky. In [[http://www.gunnerkrigg.com/archive_page.php?comicID=674 a later page,]] a [[ArtShift stylized depiction]] of Coyote appears to reference the ouroboros.
189	* ''Webcomic/{{Homestuck}}'': The two-snake symbol, specifically referencing ''Literature/TheNeverendingStory'''s use of it, is associated with the [[spoiler:Cherubs]]. [[BizarreAlienBiology It turns out to be a part of their mating process]]; when mating, they transform into immense crocodile-headed snakes, and the act is consummated when they bite each other's tails and twist themselves into an infinity symbol.
190	* ''Webcomic/KerKylsWatch'': The ruler of 29XX is named Lord Ouroboros.
191	* ''Webcomic/OzyAndMillie'': In one strip, Lewellyn, a dragon, attempts to explain the symbol, and [[https://ozyandmillie.org/2005/09/23/ozy-and-millie-2134/ provide a visual reference]] by biting on his own tail.
192	* In ''Webcomic/{{Rhapsodies}}'' the Circle Band's logo consists of the Chinese symbol "Fo" superimposed over an ouroboros
193	* A ''Webcomic/SaturdayMorningBreakfastCereal'' comic posits that the symbol was initially conceived as a discreet signal to inform potential paying audiences of buildings containing autofellatio shows.
194	* ''Webcomic/UnwindersTallComics'': In [[http://tallcomics.com/?id=76 this]] strip, there's an ouroboros in the panel border art. It's the first hint that this {{metafiction}}al webcomic is doing something amazing.

197	[[folder:Web Original]]
198	* ''WebAnimation/{{hololive}}'': One half of [[TimeMaster Ouro Kronii]]'s name is derived from this creature, as it represents time and infinity, so it's no surprise that snakes are one of her AnimalMotifs. Her New Year's 2022 kimono reveal stream also introduces a white snake mascot named Boros, bringing this reference [[{{Pun}} full circle]].
199	* ''WebAnimation/HomestarRunner'': In the Strong Bad Email on [[http://www.homestarrunner.com/sbemail174.html mini-golf,]] the "Worm Hole" dodges Homestar's putt, after which the Worm himself pops up, shouts "Get Your Own!" and takes a bite out of the golf ball. Then ''another'' Worm pops out of the golf ball, bites the first Worm, and the two end up forming an endless loop.
200	-->'''Homestar:''' [[ComicallyMissingThePoint "I'm gonna say that's a birdie. Yep... definitely a birdie."]]
201	* ''Website/{{Mortasheen}}'':
202	** The [[https://bogleech.com/mortasheen/grobbidile.htm Grobbidile]] is a useless, wormlike by-product of monster creation most notable for a potent HealingFactor and insatiable hunger for the closest source of meat. As a result, most Grobbidiles spend their lives joyfully devouring their own tails. Rarely, it can evolve into the [[OurHydrasAreDifferent hydra]]-themed [[https://bogleech.com/mortasheen/grobbydrus.htm Grobbydrus]].
203	** Before Grobbydrus was revealed, someone came up with a fanmade creature called an [[http://fawkestheskarmory.deviantart.com/art/Mortasheen-Ourobbidile-262213877 Ourobbidile]] which would be created when a Grobbidile consumes a growth serum. Their backs are lined with hard plates and they are far more aggressive than their previous forms, and attack prey by rolling at them like massive wheels and flattening them. When they lack other targets, they revert to idly chewing on their own regenerating tails.
204	* ''Website/SCPFoundation'': The Ouroboros Cycle is a long tale featuring four of the SCP-001 proposals. First is the Children, where the Foundation uses nine children to harness a dangerous power that can wipe anything out of reality. Second is the Broken God, where the Church of the Broken God revive their deity, who then goes on a rampage across Mexico, becoming bigger with each chunk of metal it gets. Third is Atonement, where a Foundation Scientist becomes like a humanoid black hole with the power to wipe out all but one world in the Multiverse and offers to do so after telling the O5 Council that the anomalies they work to contain come from other worlds and leak in. The last is The Way It Ends, which follows an elite group of Chaos Insurgency agents in a quest to kill all the O5s. The overall theme consists of the Foundation messing with power beyond their understanding and how, no matter what happens, the Foundation must remain.

207	[[folder:Western Animation]]
208	* ''WesternAnimation/{{Ninjago}}'': The main city inhabited by the first season's villains, the Serpentine, is named after the Ouroboros, with the arena in the center having carvings on the walls depicting the symbol. This ends up being foreshadowing of sorts, as [[spoiler:in the finale of season 1, the Ninja stop the [[EldritchAbomination Great Devourer]] by baiting it into running into and biting its own tail, causing it to resemble the symbol.]]
209	* ''WesternAnimation/SheRaAndThePrincessesOfPower'': The ouroboros is the symbol of Tung Lashor's gang of SnakePeople.
210	* ''WesternAnimation/StarVsTheForcesOfEvil'': Queen Eclipsa casts an Ouroboros spell on Rhombulus's snake arms. She was apparently particularly proud of this spell.

214	* Friedrich August Kekule von Stradonitz realized that the unusual properties of benzene could be explained if its carbon chain connected around in a hexagon. He claimed he got the idea after having a dream in which he saw a serpent eating its own tail.
215	* UsefulNotes/CarlJung, he of Jungian {{Archetype}}s, proto-{{troper}}, included this in his writings.
216	* It is possible that the inspiration for the symbol is the view of UsefulNotes/{{the Milky Way galaxy}} in the night sky, hence its appearances in astronomy-focused cultures.
217	* It's possible for real snakes to bite their own tails. Usually, the real-world ouroboros dies when this happens, [[https://www.tumblr.com/troperjovialjam/717859452485844993 though one can save it with a little sanitzer to make it gag]]. It's usually a result of heat delirium, where the snake can't tell that that tasty-looking moving thing is a part of it.
218	* [[https://www.youtube.com/watch?v=_pVl6_rP6DE Armadillo Lizard,]] a little lizard whose defense tactic involves curling up and biting its own tail, protecting its soft underbelly with its hard back, and as such it is given the scientific name ''Ouroboros''.
219	* [[http://www.zmescience.com/ecology/animals-ecology/ouroboros-snake/ A Stimson's Python]] in the Alice Springs Reptile Centre somehow shed its skin inside itself, with the shredded tail ending in the mouth. It broke itself free after 3 hours.
