Buccha from Air Gear is a rare Double Subversion. He eats a lot, and appears to be tremendously fat. However, he's only got about 6% body fat; his appearance is due to blood pooling in his stomach from overeating. When he exerts himself, the blood goes to his muscles, and his ridiculously sculpted body is revealed.

A rhino beastman has his horn broken off in a fight with Shirou, revealing a bone core. Rhino horns are made up of highly compressed keratin and have no bone cores, unlike the horns of bovines, sheep, or antelopes.

It's alright that biology isn't Paru Itagaki's forte, but as illustrated in Beastars, it seems to be her pianississimo:

• There is a plot point that Legosi seems to dislike his grandfather due to the fact he isn't a wolf, and Legosi and his mother are half breed wolves (quarter in Legosi's case rather.) It turns out his grandfather is a komodo dragon. Ignoring the impossibility of a mammal and a reptile having children, Legosi looks like he has only inherited a few reptilian traits from his grandfather: small pupils and immunity to komodo dragon toxins.

• A hippopotamus student is occasionally grouped with the carnivores (due Because Real-Life Hippo are Responsible for killing human beings Or any stigma attached to hostility.) While hippos occasionally scavenge on carcasses and are hyper-aggressive, they are primarily herbivores.

• And it eventually comes out that Legosi's mother developed scales similar to her father later in life that was the contributing factor to her suicide.

• As revealed in Chapter 124, Legosi isn't the only halfbreed in the series with the introduction of another hybrid character called Melon. A serial killing Leopard-Gazelle hybrid, who is forced to hide his heritage.

• This was even hammered home further with the introduction of the hybrid Daycare in Chapter 142.

• This series also gets several other things wrong about biology although some of them may be intentional. For example, it greatly exaggerates the deadliness of Komodo dragon venom. In real life they are not a very venomous species, but the series depicts Gosha has having to be extremely careful not to accidentally poison people and dripping large amounts of venom from his mouth when excited, and when he is especially upset his venom acts like Hollywood Acid. It also gets where they secrete the venom from wrong. In real life Komodo dragons secrete venom from a pair of sacks in their lower jaw, not from the upper jaw like Gosha does.

• In Chapter 154, some of the history of this civilization is revealed. Apparently when the carnivores or "life animals" first encountered the herbivores or "nature animals", some form of magical "survival instinct" triggered causing the carnivores to view the herbivores as objects of protection, rather than potential meals even though the historical account just established that the carnivores would eat each other to survive. It remains to be seen how much of this account is factual versus mythical versus revisionist history but, needless to say, the current story flies in the face of established predator/prey behavior observed in nature.

• Towards the climax of the Melon arc, some traits ascribed to some species cross the line from exaggerated to purely fantastic. Apparently, a few drops of venom from a strong komodo dragon is enough to melt a huge hole through a building wall in a matter of seconds; they can also bristle their scales like a mammal would bristle their fur. Leopard spots move on their bodies based on their thoughts or emotions. And more.

Apparently, golf skills are hereditary. Eve being able to use Kazuhiko's trademark swing is taken as the ultimate proof that she is Kazuhiko's real daughter by Amuro and Seira. And while a flashback shows that Eve was taught by her father in the past, Aoi and Himekawa also trained under him and are pointedly unable to use it, further reinforcing that Eve can do it because she shares her DNA with him. Not to mention that Aoi was able to instantly master Amuro's golf style, despite it being different from the one she had been using until that point, right before the show reveals Amuro is her real father. Needless to say, genes don't work like that.

When Ichigo has to rescue the soul of a little boy who has been trapped inside a bird for a very long time, the bird is persistently referred to in English, including the official manga and anime English translations as a "parakeet". It's not. It's a cockatiel, a bird more closely related to cockatoos than grass parakeets (such as the budgie).

Synesthesia is a phenomenon where one kind of stimulus leads to another. Synesthetic people can perceive sounds as colors or feel that numbers have a certain texture or personality. It has absolutely nothing to do with perceiving people's state of mind as colors, which is quite impossible in the real world.

• Actually, seeing auras around people can be a type of synesthesia. It could be caused by the brain interpreting emotional cues as colors (more on the ideiosthesia side of synesthesia) or interpreting pheromones and other variations of scent cues the body gives off depending on the emotions one is experiencing as color. There's also two flavors of synesthesia, projective and associative. One with the first type would see the color around someone while the second type would simply associate the color of their mood with the person.

• Outside of that, Canaan does make repeated mention of "scents", so it could be that she has a smells -> colors variety... and has a nose like a bloodhound.

• Also, synesthesia doesn't work the way it is shown in episode 10! It is a process inside our brains, so if some device (see below) does cancel out all noise, it won't reach the synesthesiac person's ears, ergo, there is no way it can be converted into any other sense and do any damage, if it's Hakko's voice.

• The explanation for all of this lies in the fact that Canaan's synesthesia is ultimately born from the Ua virus. Considering the other "Borners", there is no real reason why it would have to follow the same rules.

• Active noise control, which cancels out all sounds, is a realistic notion, except that to cancel sounds in the entire facility, as shown in episode 10, it'd have to consist of thousand of sound detectors and hundreds of anti-noise generators scattered all over the place. And a huge mainframe to process the noise data in real time.

Dolf is half-crow, half-blackbird, an impossible cross-breed, with a yellow beak that he hides by covering it with shoe polish. He also has a crooked beak that doesn't resemble either a crow's or a blackbird's and looks more like an eagle's. His father, supposedly a full crow, has the same type of beak, so we know where he inherited it from.

Losing an eye because you accidentally ricocheted a small, round-edged, plastic-looking object into it at arm range would be extremely improbable in real life. Human blinking reflex is faster than that and there wouldn't be a terrible kinetic energy involved, so the stunt would have probably ended in just an ugly black eye and/or a cut, maybe with superficial cornea damage, certainly not a burst eyeball. Possibly in-universe too if we interpret that Lui's wound wasn't actually that serious and Ukkomon mistakenly thought so because he understands human nature so bad. The scene even shows the Digivice falling to the ground after presumably rebounding off Lui's eye, further implying the damage couldn't have been deep or else it would have gotten stuck.

Doraemon: A major plot point involves Sewashi changing the past by sending Doraemon back to the 20th century to improve Nobita's future, resulting in his great-great-grandmother being changed from Jaiko to Shizuka. He demonstrates that no matter who Nobita will marry, he will always be born which is not possible due to 1/16th of his genes being different, thus, he will cease to exist. The fact that this doesn't occur in any of the mangas or adaptations so far suggests that there is something that Sewashi didn't tell or either the authors just didn't think about this.

For a series that largely backs up its science and doesn't rely much on artistic license, there are a few notable exceptions where plot needs are more important, such as the fact human beings can't actually survive being petrified in solid stone for thousands of years.

• Ruri's disease, from which she's suffered for most of her life, is eventually diagnosed as pneumonia caused by the bacteria pneumococcus. But bacterial pneumonia isn't a chronic illness, meaning that it should have gone away on its own long ago if Ruri managed to survive for this long.

• The population of the village descended from six astronauts, three males and three females. However, three of each sex is not enough diversity to build a population. In the absolute best scenario, you could have no inbreeding for four generations, after which genetic disorders and deformities will slowly kill subsequent generations.

• Foxtail Millet does not contain any gluten proteins. This makes it nigh impossible to make it into noodles like Senku does without using another grain (like wheat flour) as binder to provide the missing gluten. The resulting noodles would not be green as depicted, and would taste very different from regular ramen noodles to Senku and Gen. Of course, this is addressed - both Senku and Gen consider the product pretty awful and crumbly. There's a guy who made them for real, and they were pretty similar to what's shown in the anime.

Chitose Karasuma, After suffering from a terminal illness for so long, she has learned to alter her body temperature and go into comas at will.

Large dog breeds like Akita Inu (Gin), Tosa Inu (Musashi) and Great Danes (Ben) have an average lifespan of maximum 10-12 years (6 to 8 years in Ben's case). In the manga, the Time Skip since Nagareboshi Gin is 10 years, making it plausible for them all to still be alive (save Ben). The anime however, changes the time skip to 14 years instead, certainly pushing the boundaries, especially when wild dogs in general have a shorter lifespan than pet dogs do.

• This is especially noticeable with Ken who were born in Nagareboshi Gin and is still portrayed as roughly a young dog, in Real-Life Great Dane Saluki Hybrids in their Adult Forms They have totally different bumps when you're no longer young.

• in the Original GNBG There is no way that reddish brown Riki and Fuji would get a brindle (tigerstriped, torage) puppy together due brindle colour being dominant, meaning that at least the other parent has to be one to get the colour passed down.

Cordelia Gallo Have Several Examples:

• Her giving birth to Victorique would be fatal to her (and to Victorique to a lesser extent) in real life, with survival rate <10%:

• She was chained to a freezing-cold altar, flat on her back, with no visible assistance. Giving birth in that situation would be torturous and fatal to the mother (and eventually the child). Cordelia's petite frame doesn't help either. Not to mention she would suffer at least a 3rd degree tear during such childbirth.

• As she would suffer such serious tear, she would be susceptible to infections (postpartum infection during the period is often fatal) and would not be walk normally afterward.

• Without nursing, she would heal much slower and more susceptible to infections than nursing mothers.

Baki the Grappler, in addition to all the other insane/biologically impossible things that fighters do, Shinogi Kanno can rip out nerves with his bare hands. In a fight with Baki, he blinds him by ripping out his optic nerves; apparently unlike all other humans, his optic nerves are located in his neck. Baki then temporarily repairs them by knotting the nerve endings. Of course, he makes a full recovery. Somewhere, a neurologist is weeping.

Meta Knight and Tiff give Kirby a torch to turn into Fire Kirby because his opponent, Heavy Anaconda is a cold-blooded reptile (with the logic that fire > ice). Being "cold-blooded" doesn't literally mean one has cold blood, it means they lack the ability to thermoregulate (of course, Fire Kirby defeating Heavy Anaconda by setting it on fire would still work because, obviously, a snake would get killed by being set on fire).

• In "Shell-Shocked," Escargoon's shell being broken off is treated as embarrassing at best and it likely had nothing inside, while in reality a snail's shell houses most of its organs, meaning that breaking it off would kill it. Especially strange considering earlier in the episode Escargoon explicitly stated that his shell is less like clothes and more equivalent to one's spine.

Shizuku herself; she only allows Deme-chan to suck up things that she doesn't consider to be alive, but that seems to only include animals visible to the naked eyes; blood, for instance, is okay (this is a plot point).

• Queen of Ants After Devoring his Victims These own victims become their offsprings

• In Battle Tendency Arc. Apparently, pillar Men species evolved naturally and predates humans by hundreds of thousands of years. Don't think too hard about how. Admittedly, the crazier powers the four surviving Pillar Men show off are a result of Stone Masks altering them, but the basic traits like absorbing organic matter and being unable to survive in sunlight are all baseline Pillar Men characteristics.

• Post Art Evolution, Iggy's face looks remarkably human-like for a dog. Also, interestingly, throughout his entire appearance, Iggy's nose looks more akin to a cat's nose than a dog's.

• Kars Obviously, a male harpy with a Lovecraftian Superpower isn't going to be scientifically accurate in any way, but the thumb claws on his wings Don't have alulas.

° Risotto Nero has Three Examples:

• The adult human body contains around 4 grams of iron, only enough for a couple of razor blades, and definitely not a whole pair of scissors (assuming Metallica needs an exact ratio of iron to work with).

• On the other hand, Metallica should technically be even more lethal than it's portrayed as; to shunt all the iron in a person's bloodstream would require destroying all their hemoglobin, which would render their blood useless for delivering oxygen. While this is acknowledged with Doppio being unable to breathe, he should have been doomed by then; even if he does eat a frog and drained a young boy of blood to replenish some of his iron, the human body wouldn't be able to produce new blood cells fast enough to survive that.

• Humans don't actually have black sclera. Of course, that's assuming that he's human in the first place... Or that he's not just wearing contacts, or it's a side effect of his Stand power.

Malena Turning her into a fetus outside the womb should have killed her instantly, but Polnareff manages to keep her alive by wrapping her in a blanket until Alessi can be defeated.

While some studies show that women can have lower body temperatures, the difference is negligible. That being said, Trish shouldn't be aging that slowly from The Grateful Dead with only a few wrinkles compared to the rest of the gang's shriveled up bodies.

• Risotto Nero's Stand Metallica can create objects such as razors, nails, or scissors out of the iron in one's blood. In reality, the human body only contains about 4 grams of iron, absolutely not enough for scissors. A few razors or nails would actually be plausible, however.

In the TV anime, Pucci tells F.F. as they are being cooked alive in boiling water through him infusing a Stand power into them that makes all water they come into contact with boil instantly that the highest temperature all aquatic life on Earth can withstand is about 89.6°F or 32°C. This is true for most multicellular aquatic life, but there are some extremophile bacteria like those found near deep-sea hydrothermal vents which can withstand temperatures well above 100°C/212°F.

• Pucci accidentally using C-Moon's powers while helping a woman who's leaving a supermarket causes the woman's eggs to hatch into deformed chick embryos. In reality, store-bought eggs are not fertilized, meaning the yolk cannot become an embryo, and even if it could, the fact that it's refrigerated would ruin the incubation process.

• Jolyne's right eye is hit by the acidic spit of the stand Yo-Yo-Ma, causing it to erupt into white liquid and leaving it out of service for the rest of the fight as well as the Green Green Grass of Home fight, until Foo Fighters heals it with her plankton... somehow.

there are many instances of improbable events involving horses; one gets easily lifted briefly into the air by a single man, and some can receive certain injuries without being permanently retired

The opening for season 3 of Kaguya-sama: Love Is War briefly shows Karen doing reporting for the Mass Media Club before getting struck by lightning, with the ensuing X-Ray Sparks showing that her microphone has a bone in it.

In the Season 2 It is evident:

• The bird-type Friend is called a Spotted-billed Duck in Episode 1, while drawn with Mallard coloring.

• Greater Roadrunners are fast runners with limited flight ability, yet the Greater Roadrunner was seen flying rather than running for the entire episode.

• The narration for Tanuki in episode 8 implies that Tanukis prefer to live in wetlands and forests. Tanukis don't usually live in wetlands, and Japanese fans speculated that the staff simply quoted a passage from the Japanese Wikipedia article when doing research.

• In episode 8, Crested Ibis was captioned as a mammal.

Goes without saying. The idea that messing with human genes with nanotechnology would not only give people the strengths and abilities of animals, but also allow them to transform their bodies at will, is utterly laughable.

• While the animal facts are usually well-researched, salamanders are misclassified as reptiles, and their regenerative skills greatly exaggerated.

• Chapter 24 claims that a Bengal tiger could kill a Tyrannosaurus with a bite to the neck. Never mind the great size difference between the two predators, and the fact that the larger animal has not only one of the strongest bite forces of any animal, but also a very thick and powerful neck.

Demon Slayer: Kimetsu no Yaiba, “Breaths” are the center of all techniques performed by human demon slayers in the series. While learning how to breathe effectively is a real thing among athletes and martial artists, in here it is taken to a whole new level, proper breathing can make the characters have unprecedented control over their bodies, it can freely control their blood flow to make their muscles have super strength, it can push their bodies to move faster than bullets, it can outright stop hemorrhages by focusing hard enough; even so the series pushes Breaths as something that is not supernatural at all compared to actual demons who can cast magical demonic arts.

As expected due to the fantasy-ish setting and heavy anthromorphization; for one, bee children look nothing like their adult forms, and all worker honeybees, and therefore most honeybees, are in fact female. Also, almost everyone is drawn with four legs. And in the first series, the species of Hatch's adopted family isn't even a real type of bee.

Dodo birds, besides being extinct (presumably this is an Alternate History), cannot fly. They also make poor dirigible captains, but neither of these things bother the Kotobuki's "captain."

• The amount of blood rushing down Kate's head and the sheer time she holds it on when she's doing her negative-G stunt should have knocked her unconscious, or at least make her slightly delirious, no matter how precise she's calculating the entire thing. The series' military adviser shows that this is possible, but he also claims that the speed of her turn is significantly slowed down for dramatic effect of the shot of her flying upside down.

Zig-Zagged. The Larvae have eyes and tongues which they use as a replacement for arms for their limbless body.

In a few scenes, Jiji is shown sweating profusely. Although cats do have sweat glands, they're mostly in the pads on their feet.

Conan repeatedly knocks out people with a needle coated with some sort of general anesthesic. Not only would this require some sort of dissolving agent to get rid of the needle, possibly causing minor acid burns from repeated exposure (especially Ran's dad), but the side effects of long term anesthesia are nothing to sneeze at.

The ogre’s hippo form strangely has wolf-like fangs instead of tusks, even though most of his other animal forms remain fairly true to their species as far as the animation goes. Though to give them some credit, hippos are one of the most murderous land animals on the entire planet and, despite being herbivores, have been known to chomp on humans and other animals for territorial reasons, so it isn't just their insane bulk and size that's got Pero frightened.

Naruto was born the day of the Demon Fox attack. But at the time of the sealing, at which point Naruto can't have been older than a few hours, at most, he is shown without an umbilical stump. That usually doesn't happen until ten days after birth.

• Organ transplants tend to work a bit like LEGO with anyone being able to put pieces of other people onto themselves with minimal effort. Eyes are repeatedly removed and given to other people. In one case, a character (Madara) manages to pluck out another character (Kakakshi)'s eye by apparently just grabbing it with their bare hands when running past them during a heated battle. Even better, the character then just plops the eye into their own socket and is immediately able to use it perfectly. Another character managed to pull out his own eyes and put them into someone else's head without the other person even noticing what had happened. Human-to-animal transplants are apparently flawless, too, as seen when Itachi transplants one of Shisui's eyes into a crow, with the crow being able to use the eye without issue for over a decade. The one time that eye surgery is portrayed somewhat realistically, requiring a lengthy recovery period, it is used to temporarily write a character (Sasuke) out of the plot.

• The cells of Hashirama Senju can apparently just be implanted willy-nilly into anyone for various effects. Madara Uchiha discovered their power when, for some reason, he used pieces of Hashirama's flesh to patch his wounds. Worse, he'd bitten off and swallowed flesh, only to spit it out hours later, when it should have been dissolved by his stomach acid.

• The same thing happens with Orochimaru. Late in the story Kabuto injects Orochimaru's blood into his body and it gradually infests his body like a cancer while also giving him Orochimaru's abilities. He also does the same with the Sound Four abilities. While not too ridiculous for the ones with implied or explicit bloodline abilities, it also works for those like Tayuya who just use ordinary jutsu.
Plenty of characters suffer significant burn injuries, but only to their skin and body. Their hair and clothing (usually) remain intact.
In the sequel, Sarada can use her sharingan as a microscope to see viruses. Regardless of magnification, such a feat is impossible with visible light as viruses are just too small. Such a feat would require special dyes, ultraviolet light, or an electron microscope.

Foxes and Tanuki have Human-like Hands, This especially the Manga Showing Nenga-Sama a Bear With Follicles in His fingers. While the Feets Is Anatomically Subtle to the Real-World.

• In a scene from the manga, hair is showning on Manmaru's Armpits despite Penguins Don't have Hairs in Armpits like those Seeing in Mammals Armpits

• Monro the Mole have big frowning claws like these of Wolverine. And Lock of hair That moles in real world don't have.

The virus looks like its made of yarn and is ball shaped. (Yet, doesn't look like a typical ball of yarn). It's also apparently able to penetrate the epidermis (since merely being touched by a cat on bare skin is enough to infect people) and instantaneously becomes symptomatic.

Unless Anna's father was also Caucasian, it's almost impossible for Anna to have blue eyes.

• Marnie's features are even more unlikely. Her father is a blond, blue-eyed "foreigner" of some kind but her mother appears to be a standard Japanese beauty (black hair and dark eyes.) Needless to say, the odds that their child would be a blond, blue-eyed girl are... remote.

In One Piece: When Usopp gets hit in the face by Mr. 4's four-ton bat, an x-ray of Usopp's head briefly flashes on screen to emphasize the damage, showing that he has a bone in his long nose that gets broken by the impact.

Panty from Panty & Stocking with Garterbelt should have every STD known to man and some known only to monkeys with her sex life. Angel powers keep her safe.

Kakehashi kills the virus in Fuyoko’s bio weapon with the white arrow. Viruses are nonliving, and therefore, cannot be killed. Although, it’s possible that the literally supernatural power of the arrow terminates all processes even remotely lifelike.

The short scene showing a Spearow's point of view reveals it sees in black and white (as it did back in the first episode). Birds in Real Life are known to have good color vision, and they can distinguish colors better than people can. Though it can be excused on the account of Spearow not being a real-life bird and being a Pokemon so its vision might work differently.

In one episode of the old anime, a whale makes an appearance on-screen and eats a bunch of different creatures. One of them is a jellyfish. After eating it, he spits out its skeleton.

Yukishiro Enishi, the brother of the wife Kenshin accidentally killed, was so traumatized by witnessing the event that his hair and eyes turned white and turquoise respectively.

In chapter 45, Noko-tan finds a large egg and incubates it inside her headspace, expecting a deer will hatch from it despite deer being mammals. She's totally right, somehow. She names him Toshi-zou.

When Eikichi attempts to grope Mariko's ass underwater, a stingray bites his penis. (Real stingrays' mouths are not capable of biting humans.)

Modern banana cultivars do not have seeds and consequently can't be grown from them as Lucius is able to do with the banana he brings back to Rome from Japan. To cultivate a new banana plant, you need an offshoot from an old banana plant. This is besides the fact that bananas are not native to Egypt (where Hadrianus first tastes one), which is far from their native tropical climate.

Downplayed. Sphinx (the Cat Name, not the Egyptian Building.) is a male calico cat, which are possible but are exceptionally rare (about 1 in 3000, requiring an extra X chromasome to give the pattern). Index randomly finding him is either one hell of a lucky find or he's a product of Academy City science somehow.

throws around figures in the millions, billions, and even trillions quite freely. On the low end of this scale is Toriko himself, who is said early in the series to burn 100,000 kilocalories a day, something that would give a normal man heatstroke. There's also a technique, Monkey Martial Arts (or Enbu), that's dedicated to consciously controlling the independent wills of the 60 trillion cells in a person's body. At one point, the four main characters declare their combined might of 240 trillion cells.

Despite the unrealistic premise, this mainly was Averted with a vengeance, with one notable exception - Trainer regularly approaching horsegirls from behind and suddenly feeling their thighs. It does get him well-deserved back-kicks, but he seems to be protected by a thick layer of Plot Armor. Do Not Try This at Home - if you do it with an actual horse, even the friendly and quiet kind, you might end up killed.

In the DVD bonus episode, a manatee survives being trapped underwater for an entire day. Manatees can only hold their breath for about twenty minutes.

Hige, Toboe, and most of the minor character wolves are more brown then any real wolf, and every wolf that has markings is over simplified—although realistic ones would be hard to animate. The only visually realistically wolves are the pure white Kiba and pure black Blue. The pure black Darcia would count too, if not for his eyes being different colors.

For an in-universe example, the shop owner tells people that, since Yamataro “came from the sea” (read: was found on an ice floe), he’s a species called a “sea bear”... and can only digest fish, in Real-Life Polar Bears are both Carnivore and Piscivore and Can't Breath Underwater for For an extended period of time.
