Ah, Nessie, Nessiteras rhombopteryx, the Loch Ness Monster. Its mysterious allure and continuous camera shyness has led the Loch Ness Monster to inspire many other myths and urban legends of lake-dwelling cryptids, as well as having legends of other lakes sneak back into its own. Many lakes around the world have had local stories about the secret monster that lives at the bottom, and as the world was getting ready for the moving pictures, a lot of these separate myths consolidated into one shared stock trope about hidden lake creatures waiting to be found by open-minded zoologists.
The creature is prone to travelling around the surface like an iceberg with a small section peeping out at the top (often making it cunningly indistinguishable from a log when seen by a Caledonian drunk) while its main body lies hidden beneath the surface. Explanations often revolve around its being some ancient or long-lost creature found miles away from where it would be expected, locked in by changes of geography, in an ecology often far too small actually to support it unless it devoted itself to eating once a year and never breeding.
There is also often a plot that goes along with these beasts that decks the halls of Syfy Originals. Some idiot starts the plot by becoming kelpie chow. Some low-paid fringe scientist, with fewer peer-reviewed papers and far better looks than any normal scientist, will go or be forced out there to investigate alongside a gruff, no-nonsense local and a wacky comedy sidekick, daring to find the truth while being threatened with ridicule and/or group buggery by the other locals.
The earliest written mention of Nessie may be in a 7th century biography of St. Columba who saved a swimmer being pursued by a "water beast" in Loch (river) Nessby making the sign of the cross.
A number of myths also have their creatures as helpful or at least sufficiently beautiful to not want to kill, so there's also a softer side to the trope where the creature will be friendly. The myths of Nessie being a plesiosaur help play into that, being a slightly more friendly-looking form than a giant eel or a floating turd.
These creatures may sometimes be linked to Sea Serpents. When this is so, either kind may be modelled after the other, either with lake serpents being portrayed as more snakelike than they usually are or sea serpents gaining features such as flippers and plesiosaur-like necks.
Occasionally, the monster will turn out to have been something completely different.
Is not in any way related to the name of an RPG protagonist.
- The Loch Trevor Monster in Superman's Pal, Jimmy Olsen (and later Project Cadmus-related comics).
- One of those elements used again and again and again in Disney Mouse and Duck Comics, whether in the form of an expy or the original. Carl Barks already did it, but that didn't keep everyone else from doing it, too.
- Near the end of the comic strip run of U.S. Acres (aka. Orson's Farm), there was a week-long storyline involving Wade discovering that a giant Cloud Cuckoo Lander sea serpent is living in the water trough. Naturally, Wade is the only one who sees him. (The storyline can be seen a Platypus Comix article about the comic here.)
- The Fabulous Furry Freak Brothers: In one episode, Franklin is attacked by whole swarm of Loch Ness Monsters. "Only an inch long, but icky as Hell!"
- Nessie's Roman-era ancestor makes an appearance in Asterix and the Picts.
- Ringo from Phoebe and Her Unicorn, who is a Nessie-like monster that lives in the lake near a summer camp Phoebe attends. He also happens to be friends with a Creepy Child named Sue, and Marigold develops a crush on him (in spite of her being a unicorn) though he is Oblivious to Love.
- In A Thing of Vikings, Hiccup has visited Loch Ness during his trips to Britain to investigate rumours of a Tidal-class dragon living there, but so far he has found nothing to confirm or deny the theory that such a creature exists.
- Lake Placid had a giant crocodile, which was raised by a surprisingly foul-mouthed Betty White, and was running amok eating people. As it turns out, there's actually two of them. And they had babies. At least 10.
- In Monster Trucks, once scientists discover the underground lake hosting Creach and his species, the creatures are compared at least once to the Loch Ness Monster.
- The 1996 film Loch Ness in which an American scientist trying to disprove the existence of the Monster, only to later disprove his own evidence when he accidentally finds it.
- The Water Horse posits that the titular creature is a dinosaur-like beast which reproduces by laying a single egg and dying, so only one is in existence at a time.
- Beyond Loch Ness is a Syfy Channel B-movie about the titular creature... in Lake Superior. Yes, you read that right. Granted it's explained Nessie migrates between the oceans and various lakes, she just happened to be in Loch Ness when she was seen in the first part of the film.
- Amazon Women on the Moon reveals that Nessie was also Jack the Ripper.
- And speaking of Amazon Women on the Moon, its Nessie prop is originally from the 1981 Loch Ness monster movie directed by Larry Buchanan - The Loch Ness Horror.
- Baby: Secret of the Lost Legend is about the Congolese Nessie a.k.a. Mokèlé-Mbèmbé (a Lake Monster thought to be a Brontosaur in Africa).
- The Librarian: The third film depicts Nessie as a plesiosaurus, which is being held in The Library.
- A tourist had decided to visit the Loch Ness lake, in the hopes of seeing the famous monster. Looking for information, he asks a local:
Tourist: Tell me; when does the monster usually appear?
Local: Usually after the sixth glass, mister.
- Danny Dunn and his friends once went searching for a lake monster in central Africa, thinking it might be a dinosaur. It turned out to be (no, really!) a giant electric walking catfish.
- Steve Alten writes a lot of books with Sea Monsters. A recent novel, The Loch, deals with, of course, the Loch Ness Monster. In a twist however, Nessie isn't a peaceful plesiosaur (it's pointed out that Nessie couldn't be a plesiosaur since if it was an air-breathing creature there'd be a hell of a lot more sightings of it) but a giant eel with a taste for tourists. Turns out it and several like it were put there by an ancient Scottish order, then trapped and brain-damaged by construction and pollution. That caused them to grow to an unnatural size, broke their normal food chain, and turned them savage.
- Fantastic Beasts and Where to Find Them explains that the Loch Ness monster is actually a shapeshifting lake monster that turns into an otter when Muggle tourists are around.
- The Amazing Dr Darwin: Erasmus Darwin had an encounter with this critter.
- Star Trek: Stargazer: According to the novels, the trope isn't just confined to Earth. The Kandilkari have "The Lake Dweller That Roars", though it's unclear as to whether it's real or not. Nol Kastiigan seems to think so, but it's not certain.
- Redwall: High Rhulain features the reptilian Slothunog. It's only on one page, but it makes up for it by being the most awesome page in the book. There's also the Deepcoiler in Salamandastron, a giant carnivorous eel that lives in a great inland lake. The shrews thought it was a myth. They were wrong.
- Anthill A Novel by E. O. Wilson mentions one. It's probably just a myth.
- Illuminatus!: Nessie makes a brief cameo.
- In Voyage of the Basset the sea serpent looks like this. In a variation on the "monster" bit, he's actually a good creature.
- Hometown: Shady. An odd and suspicious case, since all sightings (and attacks) report a creature far too large to survive and stay hidden in the bodies of water where the sightings took place. And yet the bodies, mauled by an unknown but appropriately-sized animal, keep turning up.
- Dinoverse: When Janine's sent back in time and encounters an Elasmosaurus she immediately nicknames Nessie. Nessie's a big time Prehistoric Monster here, going after pterosaurs and using its neck like a constrictor snake to attack a Tyrannosaurus rex that was wading in the shallows.
- The Blackbury Monster in "The Blackbury Monster" by Terry Pratchett, one of the early stories collected in Dragons at Crumbling Castle. This may or may not be related to the time Johnny Maxwell claimed to have found Nessie in his goldfish pond.
- Alice, Girl from the Future had a dragon from The Time of Myths say that Nessie is probably his niece; she was very lazy; so once she met Archimedes and learned from him that anything submerged in the water loses a lot of weight, she decided to live in the water so as to avoid carrying that weight.
- InCryptid, utterly unsurprisingly, has a number of these. The first that the reader sees is the Michigan Lake Monster, which features prominently in the short story "Loch and Key." A second plesiosaur appears in the Cold Open of Chaos Choreography, the pet of a trio of archaeology students from a Portland-area community college, whom Verity and her husband Dominic move from a city reservoir to a much more secluded lake high in the mountains. Specifically noted as not being sea monsters, as these are freshwater beasts and will quickly die if introduced to the ocean.
- The Loch Moose Monster in Mirabile. The protagonist finds out what it really is early on, but takes inspiration from the original Nessie and encourages her friends at the Loch Moose Lodge to play it up as a mysterious tourist attraction, complete with deliberately fuzzy photographs and the like, because the people of Mirabile tend to be nervous around new species (with good reason in many cases) and she doesn't want anybody panicking and wiping it out before it has a chance to get established.
- Thomas Thiemeyer's sci-fi novel Reptilia deals with the "African Nessie" Mokèlé-Mbèmbé, said to be a sauropode in Real Life though in the novel is more similar to Nessie and is an alien.
- Ology Series: Monsterology includes lake serpents, immensely long-lived plesiosaur-like animals found all over the world, in its chapter on water-dwelling animals. Since only one is known to live in any given lake, no one knows how they manage to reproduce.
- Hattie & Hudson: Hudson is a lake monster that resembles some type of plesiosaur.
- Event Group:
- Some odd, turtle-shelled plesiosaurs show up in a lagoon in Brazil in book 2.
- According to book 4, the Loch Ness Monster used to be real, but the species went extinct during World War II.
- In The Andy Griffith Show reunion movie Return to Mayberry some locals - including Earnest T. Bass - try to convince people there's a lake monster.
- In Bewitched the Loch Ness Monster is actually an old warlock boyfriend of Samantha's who got transformed into a monster.
- Doctor Who:
- The Skarasen (a.k.a. the Loch Ness Monster) from the 1975 serial "Terror of the Zygons". Much later on, Sarah Jane was able to namedrop the Loch Ness Monster during an argument with Rose as to which Companion endured the most incredible "space stuff". Rose couldn't trump it. ("School Reunion")
- In a case of Negative Continuity, the Borad becomes the Loch Ness Monster in the Sixth Doctor serial "Timelash".
- The paradox was cleared up in the Eighth Doctor Adventures novel The Taking of Planet 5, when the Borad is eliminated just after his arrival in the past by a Time Lord clean-up crew.
- The Goodies get hired to capture the Loch Ness Monster in the episode "Scotland". They return with a man in a Nessie costume. And a real Nessie egg. Which hatches.
- The Lost Tapes episode "Monster of Monterey" contemplates that one or more elasmosaurs (carnivorous marine reptiles of the plesiosaur order) may inhabit Monterey Canyon and are responsible for many of the mysterious disappearances amongst sailors in those waters, with the ominous shadow that twice glides past the boat looking very much like the plesiosaur silhouette. The creature itself was based on the Zuiyo-maru carcass, aka "New Nessie," the remains of a dead sea creature which bore an uncanny resemblance to a plesiosaur.
- On an episode of Married... with Children in which Al claims to have been visited by aliens, daughter Kelly tells him, "And by the way, the Loch Ness Monster and Bigfoot wanted to know if you're still on for poker at Darth Vader's house tomorrow night."
- In the first episode of Monster Quest, the suggestion that "Champ", or "the American Loch Ness Monster" could be a plesiosaur is bandied about. In another episode, they were searching for "Ogopogo", and they found what they believed was a dead baby Ogopogo... and it turned out to be a decomposed salmon or trout fillet.
- Some of the giant fish pursued on River Monsters have a reputation for bumping boats or dragging fishermen into the water, feats often attributed to the scarier versions of this trope. Jeremy Wade eventually did a two-hour episode devoted to Nessie. He didn't catch her, obviously, but he explored various possibilities of the creature's identity and eventually concluded that a Greenland shark was the most likely suspect.
- The X-Files episode "Quagmire": Mulder and Scully investigate reports of a lake serpent and find a surprisingly ordinary (albeit still deadly) crocodile. This being The X-Files, however, after they've left, a The End... Or Is It? ending shows there really is a serpent in the lake.
- A few of the "Unexplained" segments on Unsolved Mysteries featured searches for varying versions of these—New York/Vermont/Quebec is believed to have one inhabiting Lake Champlain (which is bordered by the two states and the province), appropriately named "Champ"
- The Police's "Synchronicity II", besides singing about an emasculated frustrated man living in a suburban family hellhole, makes vague mention of a mysterious creature in a Scottish lake "many miles away" (possibly referring to the Loch Ness Monster).
- "Loch Ness Monster" by Big Dipper, where the narrator's boat is bumped into by the title creature, and he becomes obsessed with making a second encounter and getting evidence. The lyrics are also a deliberately silly metaphor for unrequited love - Nessie is referred to with feminine pronouns, and in the bridge the narrator laments "It's a mystery / why she left me".
- Nessie, of course, is the most famous of the lot. Interestingly, its fame is a fairly recent phenomenon, largely resulting from alleged sightings in the 1930s: before that, it was just another local legend like many, many, many others. Many of the "imitators" were already recorded in local folklore long before Nessie became famous.
- Canada has several, including Ogopogo (which is actually protected under provincial legislation, just in case) in the Okanagan Valley lakes and its cousin Manipogo (who lives in Manitoba), and Memphré (in Quebec/Vermont, the first recorded North American monster). All of them were recorded in local legend long before the 1930s; as far back as the 1810s for Memphré.
- There are many, many, many others:
- Champ is probably the most famous North American one, dwelling in Lake Champlain. Champ was noted to have a horse's head and a serpent's body... And yes, it was recorded in local folklore several decades before Nessie became an international star.
- The Storsjö Monster or "Storsie" in Jämtland, Sweden, the earliest sightings of which go back to the 17th century. Along with its hypothetical nest and eggs, the monster was officially a protected species until some smartass asked for a license to collect its eggs and the authorities had no choice but to declare the protection frivolous and repeal it.
- See also the Bear Lake Monster of Bear Lake, Idaho.
- Central Africa's lake monsters tend to overlap with Living Dinosaurs, such as the Mokele-Mbembe, which is purported by some to be a surviving sauropod, although local descriptions indicate it may actually be an undiscovered species of semi-aquatic, long-necked rhinoceros.
- The Iliamna Lake Monster, supposedly said to occupy Lake Iliamna in Alaska, although eyewitness accounts and Native American legends related to them suggest they're some sort of gargantuan sturgeon-like fish, not plesiosaur-like creatures.
- The Other Wiki, as a matter of fact, has a rather impressive list of reported lake monsters from all over the world.
- In Safe Havens, Samantha theorizes that plesiosaurs were what ancient merfolk looked like, as she noticed, between the half-human merfolk on Earth, and the half dodo merfolk on Mars, that she believes merfolk's top half reflects the dominant species of the time. Hence, plesiosaurs in the time of the dinosaurs.
- Martin Ruane (1945-1998), while better known in his native England as Giant Haystacks, also competed as Loch Ness in Stampede Wrestling and was in WCW for a month, debuting in February 1996 before the SuperBrawl VI PPV as a member of the Dungeon of Doom before he left the group in March. His last appearance saw the Giant (The Big Show) defeat him at the Uncensored PPV on March 24. His run was cut short due to health problems.
- Parodied to heck and back in the Hamish and Dougal episode "The Monster of the Loch". First, Hamish and Dougal are fishing, when they're attacked by a monster with bark like skin, and twig-like claws, and branch-like arms, and leaf-like scales. Then, when they've discovered it's actually a log and used it to start a fire, the Laird complains that now they don't have a log that looks like a monster, there's nothing to attract gullible tourists to the Glen. So he spends a week in his lab while watching Frankenstein and Godzilla and creates ... another log. And then the monster turns out to be Real After All, but the Laird is so infuriated by it eating his log that he shoots it.
Dougal: So we did have a monster ... and you killed it. And now we don't even have a log.
- That Mitchell and Webb Sound: As a result of a Kickstarter joke Gone Horribly Wrong, a group of scientists drain Loch Ness to find Nessia... and determine it did indeed exist. Of course, as a result of their actions, they killed the creature, rendering the entire endeavour pointless. Also, re-filling the Loch is going to take several thousand years.
- The Champions supplement Kingdom of Champions (which deals with superhero adventures set in the UK) has several pages on "Nessie", offering four different optional explanations (Fake, Wildlife, Supernatural, and Alien) for game use. The book also has brief notes on sea serpent stories, and a supervillain group (the Shark Squad) whose minisubs look like sea monsters.
- The 3rd edition supplement Places of Mystery has a brief entry on Loch Ness (one of the few non-man-made locations in the book) which points out the problems with attempting a "realistic" treatment of the monster (it would probably have to be a large sturgeon), but notes that a supernatural monster might have been the result of some typically dubious behaviour by Aleister Crowley.
- In the Transhuman Space setting, the secret Society for Applied Teratology (detailed in the Toxic Memes supplement) recreates famous cryptozoological species by advanced bioengineering, mostly to make the world a more interesting place. Their Nessie (covered in more detail in Bio-Tech 2100) isn't doing so well, but is an ongoing project; they may create further monsters for other lakes (some of which may be more hospitable for the purpose).
- In Magic: The Gathering, there's the Gitrog, a monstrous froglike beast that appears in the short story Sacrifice, haunting a mountain lake next to a village. The heroine thought it was a myth, the villagers worshipped it. The villagers got eaten anyway and the girl ended up worshipping it too.
- Pathfinder's Bestiary 2 includes stats for them under the name of Water Orm.
- Ravenloft has an undead lake monster. One assumes it was a living lake monster at some previous point.
- Shadowrun: Lake serpents are reptilian creatures with long tails and necks, pronounced humps and plesiosaur-like flippers. They're generally considered to be lesser relatives of dragons, and are closely related to Sea Serpents, from which they're distinguished by their smaller sizes and herbivorous diets. Some speculate that they've been around all along and that things such as Nessie and Ogopogo are examples of early sightings; certainly, the Loch Ness pods are the most well-known lake serpents in the setting's modern day.
- Busch Gardens Williamsburg has a roller coaster called Loch Ness Monster that's naturally themed around the beast.
- The Spellcasting Series: The Lok Pik Monster. It basically serves as the You Shall Not Pass! guardian of the first game's final chapter.
- Psychonauts: While not quite a sea serpent or plesiosaur, the game nonetheless has its own lake monster — the Hideous Hulking Lungfish of Lake Oblongata, who is... an enormous, mutated lungfish who lives at the bottom of Lake Oblongata. Her real name is Linda. She's pretty nice when she's not being brainwashed by the Big Bad into kidnapping kids.
- Ace Attorney: "Gourdy" is a monster of unknown attributes that supposedly lives in Gourd Lake. Lotta Hart's attempts to get a picture of him become a key plot element in case 1-4. While there's no canon evidence of Gourdy's existence, a piece of official fanart shows the cast enjoying a picnic by the lake while a dark Nessie-like shape is seen poking out of the lake in the far background.
- Lapras is a plesiosaur, the sort of creature Nessie is often explained as being, and its production name was Ness. Draw your own conclusions.
- Gyarados is based on legends about magic carp jumping over the dragon gate and becoming dragons, but its abode being in lakes seems to be inspired by lake monster myths.
- Monster Rancher has the Lesione, which is like a cross between a plesiosaur and a trained sea lion. In the advanced games, one Lesione plays the role of a lake monster.
- EarthBound has the gentle and friendly Tessie, the Lawyer-Friendly Cameo of the Loch Ness Monster. Mother 3 follows up both of these with the Oh-So-Snake, in the well beneath Osohe Castle. Tessie also makes a reappearance, though she's stuffed and mounted in Porky's tower.
- Shadow of the Colossus features the wading lake monster, which is rather more frustrating.
- There's also Sally, the Lake Salamanca monster in City of Heroes. Sally is peaceful, though, and dives below the water if you attack her. And attacking her was the only way to get the Believer badge.
- Mega Man Star Force 2 involves the legend of Messie, a sea monster supposedly found in (say it with me) Loch Mess. People have been seeing it recently, but it turns out to be a fake. There is a real Messie, though — and its elusiveness is explained by the fact that it's an EM being, invisible to most people. It ends up fusing with the guy who created the fake Messie to become a rather nasty boss, Plesio Surf. Incidentally, something funny went on in translation here. The character's English name refers to the longstanding theory that the "real" Loch Ness Monster is a plesiosaur. But the original Japanese name is Brachio Wave — referring to the Brachiosaurus, which did sorta look like a plesiosaur from the neck up, but didn't live underwater. Between this and its incredible size (40 feet tall and twice as long, making it one of the most colossal creatures ever to walk the Earth), a Brachiosaurus couldn't hide in Loch Ness if it wanted to.
- World of Warcraft has an underground tram running from Ironforge to Stormwind. In the middle, the tram runs between two humongous aquaria. One aquarium contains a plesiosaur named "Nessy".
- Nancy Drew: In Danger on Deception Island, Nancy has to assemble a model of the local legendary sea monster as one of her Solve the Soup Cans tasks. It naturally resembles a plesiosaur, although the actual creature never appears in the game until the end in a photograph. Said creature is also a "real" cryptid called the Cadborosaurus a.k.a. Caddy.
- Zoo Tycoon: There's an easter egg in the original game that will let you keep these in your zoo.

- The Sims: Occasionally, one of these swims down the river in the Neighborhood view. It's a random event, and not in any way related to any of the games going on in the households.
- Super Mario Bros.:
- Super Mario 64 has Dorrie, found swimming in the underground lake in Hazy Maze Cave. Signs leading up to the area warn of a terrible monster, but it turns out to be completely harmless, and in fact even friendly and helpful to Mario.
- Super Mario 3D World introduces Plessie, another friendly lake monster type that lets the characters ride on its back and dash through river levels.
- Mass Effect 3: Mentioned in the DLC Leviathan, when Shepard sees a plesiosaur skeleton hanging from the ceiling of a lab.

- The graphical adventure text adventure Cryptozookeeper features a mission to bring the Loch Ness Monster into the game.
- Transarctica has a bridge over a lake in the north-western part of game map guarded by this monster. Crossing it without the unique harpoon car, which can obtained in only one location, is definitely a bad idea.
- The Touhou game Urban Legend in Limbo has Nessie as Nitori's urban legend theme. She and the rest of the kappa have built a Nessie-shaped robot based on the legend, so they can easily make "evidence" of the monster, and profit off of it. Due to the nature of Gensokyo, however, Nitori is eventually stalked by a real Loch Ness monster.
- In The Darkside Detective, the "Loch Mess" case revolves around one living in one of the lakes that gives Twin Lakes its name.
- Commander Keen: in the third game, a Nessie-like creature called Messie can be seen swimming in the seas of Vorticon VI. It is actually possible for Keen to hop on it's back and hitch a ride, which is the only (non-cheating) way to reach this game's Bonus Level.

- The April Fools' Day episode of TierZoo discussed the Loch Ness Monster during its look at cryptid builds. It was assumed to be a plesiosaur build that manged to survive the massive balance patch that banned most prehistoric reptile players. Plesiosaurs were top-tier builds prior to the patch thanks to their long reach proving useful for catching schools of fish, and Nessie would fair just as well in the current metagame. In fact, there's no way that the Loch Ness server could ever suport a build as overpowered as Nessie, which is a point against its very existence.
- TREY The Explainer did a three-part video series on Nessie. While he ultimately deemed it a myth, he speculated that if it were a real animal, it would be a freakishly large species of cold-water leechnote .

Scooby met a lake monster that was compared to Nessie in The New Scooby Doo Movies episode "Loch Ness Mess" and met Nessie again (apparently out of continuity) in the Scooby's All-Stars episode "A Highland Fling with a Monstrous Thing."
- An episode of The Simpsons was actually about Homer and Mr. Burns attempting to capture the Loch Ness Monster.

- The Fairly OddParents features the spoofing "Loch Dimmsdale Monster" (with the loch also spoofing), in one scene after Timmy Turner lost track of Poof, he went searching in the loch and mistook the monster's ball-shaped tip of the nose as Poof.
- Some people believe Nessie to belong to the now-extinct Plesiosauria, an order of sea-dwelling reptiles (some growing 30 or 40 feet in length) which did look like the monster.
- Most researchers rule this out as improbable, since the plesiosaurs were primarily saltwater creatures, and supposedly went extinct millions of years ago - as opposed to the 10,000 year-old lake Loch Ness.
- Aside from the ever-popular (but highly improbable) "plesiosaur" theory, Nessie's been speculated to be things like a giant long-necked seal, a large eel or sturgeon, a monster salamander, a huge slug, and even an escaped circus elephant.
- Hyphalosaurus was pretty much the closest equivalent to a real Nessie: it was a long-necked, completely aquatic freshwater reptile that lived in what was once a large lake in a temperate climate. Unfortunately, it less than a meter long and lived in the early Cretaceous... though relatives might have survived in Europe until the Ice Ages.
- Minne the Lake Creature, a (statue, sadly) monster who "lives" in the lakes around Minneapolis.
- Hippo, seal, otter and manatee sightings have all been misreported as Stock Ness Monster encounters. The first, at least, occasionally do earn the "monster" part of the title, attacking swimmers or small boats in defense of their territories or young.
- Not exactly a dinosaur, but an unidentified animal looking something like a seal-manatee cross keeps lolling around the waters of Miami, captured on film by a Gene Sowerwine. Already there have been attempts to consider it a modern variation of a mosasaur... although closer inspection suggests the animal is just an ordinary manatee, albeit with a deformed tailfin (most likely the result of having an unfortunate encounter with a boat propeller). It has also been speculated that it might be a living Caribbean monk seal, a species of seal that is thought to have gone extinct in the 1950s.
- Brickly, the Lego Ness Monster who inhabits the lake at Downtown Disney outside the Lego store. While Legoland already has a pair of dragon mascots (Ollie and Allie), when they began building a Legoland in Florida, enough people asked if Brickly was going to be the mascot for Legoland Florida that they decided to make it canon-and released a special edition set just for him.
- The specific name of the Loch Ness Monster, Nessiteras rhombopteryx ("the monster of Ness with the diamond shaped fin") was devised in the 1970s by the naturalist Peter Scott. It's an anagram of 'monster hoax by Sir Peter S', though Scott denied this was intentional and fellow Nessie researcher Robert H. Rines (who took two supposed pictures of the monster) pointed out the anagram could also be read as: 'Yes, both pix are monsters, R.' However, according to the rules of the International Code of Zoological Nomenclature, the name cannot be considered official because the is no specimen for it to be attached to.
- A number of them are also proven hoaxes, like the Silver Lake Monster of New York, which was an inflatable dummy created by a hotel owner as a tourist trap (although Native American legends from the region suggest the creature is Older Than They Think).
- One possible explanation for plesiosaur-shaped sea monsters is the partly-decomposed carcass of a basking shark (the lower jaw rotting away to leave only the spine and fins).
Stock and Loch don't rhyme? Well for God's sake then, don't tell anyone else.
