* ''TabletopGame/{{Warhammer 40000}}'': {{Space Marine}}s, just ([[SuperSoldier acid spitting, one-ribbed, three-lunged, two-hearted, two-stomached, electric skinned, super strength, reinforced skeleton, fast healing, power armored]]) {{Space Marine}}s.[[labelnote:Elaboration]]At worst, the idea of Space Marines having a single rib bone as hard as armor that encases their lungs would self-defeating for their lungs, as the rib cage isn't all bone since it needs to be flexible to not hamper the lungs expanding while breathing in[[/labelnote]]

* ''Literature/{{Hothouse}}'' by Creator/BrianAldiss. It has giant insects, man-eating plants, people growing wings after being [[SpaceIsMagic mutated by space radiation]], the entire planet being covered by a single banyan tree, and ''[[GiantSpider giant plant-spider hybrids]] that use their webs to connect the Earth to the Moon''. The publisher even admitted that he knew it was ridiculously unrealistic, but still published it because it was awesome. Which turned out to be good move, because it ended up winning a Hugo award.

* In ''Anime/ScienceNinjaTeamGatchaman'', there is an episode generally referred to among fans as 'The Puppy Episode' (#20). In it, G-2 receives a hit that leaves a bit of shrapnel in his head -in an inoperable location. The good Doctor who is the Xavier for the team -and who is repeatedly shown ''not'' to be a medical doctor, but a scientist- decides that the only way to get the shrapnel out is to ''stick G-2 in a giant centrifuge'' normally used for G-forces training. G-2 later escapes and joins his team on the Godphoenix. The final explosion and death throes of the giant mole mecha (yes, really) send the ship into a massive series of spins -which removes the shrapnel. Somehow.
** The puppy of the fan title was rescued by G-2, resulting in his injury. The set-up was to show him as a softer character then the hard revenge-driven type he had so far been shown to be -but how drastically they fail in how medicine really works overshadows the moment of heartwarming.

* Anything and everything about [[FetishFuel vore]]. [[SchmuckBait Don't look for it unless you want to be scarred.]]
** Typical sites actually separate the realistic vore as "Hard vore". Usually it's decided by whether or not there is stomach acid present and whether or not the prey dies. Excretion is not taken into account. If the prey is unharmed, alive, and [[MST3KMantra undigested when they come out]], it still counts as soft.

* ''Franchise/{{Godzilla}}'' is a prime example of this trope. It's best not to think too hard about how a [[AttackOfThe50FootWhatever giant radioactive dinosaur, giant butterfly, or half-plant half-Godzilla hybrid]] is able to exist. Just invoke the RuleOfCool, a bit of TechnoBabble, and perhaps the AnthropicPrinciple (you can't have Godzilla films without Godzilla) and be done with it. ''[[http://www.angelfire.com/ego/g_saga/kaijubiologyarticle.html This page]] attempts to scientifically explain how Kaiju could possibly exist. To summarize, they're basically reanimated corpses whose cells have been transformed into microscopic fission reactors.

* ''Vurt'' is [[ArcNumber big on fives]]. So it has FiveRaces, five [[HalfHumanHybrids two-way]] [[NonhumanHumanoidHybrid mixes]], five three-way mixes, and five four-way mixes, plus one purely theoretical combination of all five races. This means that some two-way mixes can breed with partners that one of their parents couldn't breed with, which is genetically improbable--but since one of the viable pairings is human and ''dog'', it's also probable that TheyJustDidntCare.

* Another film with risible but plot-critical errors: ''Film/JawsTheRevenge''. Most glaring is how the shark decides to kill a family out of revenge, [[VoodooShark even though the very concept of revenge is well beyond the mental capacity of a shark]]. (Or is it?..... Other fish do seem to have this concept) Also, this shark died in the original ''Jaws'' but apparently got better. How would it recognize relatives of Martin Brody, anyway? It also is able to travel from Martha's Vinyard to the Bahamas (which is too warm for great whites) in three days. And it roars. [[IfItSwimsItFlies And leaps into the air]]. [[DepartmentOfRedundancyDepartment And it roars.]]
** The Bahamas isn't actually too warm for great whites. As endotherms they can tolerate a wide range of temperatures.

* ''Manga/{{Toriko}}'' thrives on this trope. A gigantic mammoth that the heroes go spelunking inside, searching for the most delicious piece of meat. An overabundance of large predators eating each other. Flowers that detect how {{Badass}} you are. A guy with a skeleton consisting of 4000 bones. Then there are all the absurd food ingredients. The anime is even worse than the manga, having animals that are ''biologically impossible'' as well as environments that don't make one lick of sense.

* There has [[http://www.messybeast.com/self-solid.htm never, ever been an actual self-colored red cat]], as a few of the characters in ''Disney/TheAristocats'' are. This is genetically impossible due to red fur being linked to tabby stripes. There are two red coat patterns that could be mistaken for self reds: a diluted red, or cream, can have tabby stripes that are very faint and easy to look over, especially from a distance. A long haired red tabby might also be mistaken for a self red because the fur length can confuse the pattern. Neither of these shows up, as Thomas O' Malley and the orange kitten Toulouse are a vivid red and, as far as one can tell, do not have very long fur.

* All the gigantified radioactive animals in ''VideoGame/{{Fallout}}''. WordOfGod states that the ''VideoGame/{{Fallout}}'' universe [[JustifiedTrope intentionally runs on]] HollywoodScience.

* The ''Film/{{Species}}'' movies, especially the second one. A film about the difficulties Creator/NatashaHenstridge has getting laid...
** The fate of TheVirus-infected astronaut's human victims in ''SpeciesII'': his Evil Spawn go from conception to full term in ''minutes'' and then tear their way out of their hosts like chest bursters. This is ridiculous because, whatever alien biology the fetus has, it needs nutrients from its human mother to survive; the human uterus could never supply enough to allow such growth rates. These things need to assimilate as much as nine pounds of material in minutes; even ''Franchise/{{Alien}}'' chest bursters usually had the decency to take a couple of hours. Then there's the part where the infected astronaut blew off his own head with a shotgun and not only survived but also retained his memories, which is like smashing your hard drive, getting a new one, and expecting your old files to still be there when you plug it in.

** Not ''made'' from a dog, he was reincarnated as a kangaroo-man ultimate fighting machine bioengineered thing after having ''been'' a dog in a past life.

* Although there is no official explanation given as to the how [[TheVirus the Rage virus]] in ''Film/TwentyEightDaysLater'' works after infecting a victim, the virus apparently infects its host after a single heartbeat. Also, the infected don't eat, they don't drink, it's debatable whether or not they sleep, and they're constantly vomiting copious amounts of their own blood. How could they possibly live for a total of 28 days before falling over dead from starvation?

* The 'farm humans for energy' backstory from ''Film/TheMatrix'' makes less than no sense. One much better solution for the machines would be to simply burn the humans and whatever they were feeding humans with. Humans were originally supposed to be organic computer hardware for the machines, which is at least somewhat plausible. However, the Wachowski Brothers were [[ExecutiveMeddling told to change that]] since the execs were worried [[ViewersAreMorons people wouldn't understand it]].

* ''Franchise/{{Alien}}'': The creatures are so cool, it's easy to overlook the impossibility of the fast growth cycles (even before being sped up in the ''Franchise/AlienVsPredator'' movies) no matter how much it ate in that time, the fact that a creature outside of Earth is compatible with species from Earth even as a parasite, that silicon-based lifeforms aren't actually likely due to how silicon bonds, and how blood like that can work. Basically these things are powered by RuleOfCool and RuleOfScary.

* Maggie Stiefvater's ''Literature/{{Shiver}}'' werewolf series has a rather... odd explanation for werewolf transformation. Once you're bitten, the transformation into a full-blown wolf is triggered by cold temperatures. (Living in a hot climate to stop this has no effect, since even a sudden blast of air conditioning can kick off the transformation.) But it's not this. In one of the books, one of the characters has not taken well to being bitten, and it is then discovered that perhaps bacterial meningitis could stop the transformation, seeing as breaking out into a fever pre-transformation almost cured one of the characters. So yeah... injecting somebody with bacterial meningitis somehow ''helps'' rather than hinders.

* Almost all modern examples of NuclearNasty, where it's clear they don't actually think radiation works that way (I.E. creating monsters) but are doing it merely for the sheer RuleOfCool.
* Likewise, practically every example of the ZombieApocalypse genre requires that viewers ignore the issue of where the living dead get their capacity to move, if they lack a metabolism to generate energy and their tissues are so decayed that muscle contraction and neural signaling shouldn't be possible. Even variants in which the "zombies" are biologically alive tend to neglect things like the ravening hordes' need for water or rest.

*** Convergent evolution.

* In a ''Series/{{Battlestar Galactica|Reimagined}}'' episode (season 2, episode 13), Dr. Baltar heals president Roslin's cancer by injecting her with some cylon/human hybrid blood that is more resistant to diseases because it has no antigens (particles that are recognized as hostile by the immune system) and therefore "no blood type". Therefore, it is somehow capable of destroying a cancer in a very late stage. If Type O negative blood (the real type closest to having "no antigens") could do that, there would be a lot less cancer in the world...
