This Query is part of the Worldbuilding Resources Article.

As you all know there is a series of questions that have been asked to create fictional creatures in a realistic evolutionary way.

And below is a summarized list of all of the questions in order of post, so that a link to this meta post should be enough for future questions.



Due to a large amount of low quality question using this series' formula, user JBH has suggested adding specifications to the core idea of the series. Below are the most recent rendition of the rules as of April 27 2018. If a question has used the title Anatomically Correct and you feel it's poorly executed, please link to this post.

The Anatomically Correct (AC) series of questions are a popular tradition on Worldbuilding.SE. Their purpose is to invite site participants to consider how to describe fictional or mythological creatures from an evolutionary context with as much biological and behavioral realism as possible.

  • In keeping with the Stack's general rule of not fielding questions about 3rd party or commercial worlds, the ACS is now limited to questions about documented myths and legends of Humanity and creatures thoroughly designed (other than lacking anatomical fulfillment) for a fictional world of the OP's own creation. (Source)

It is the responsibility of the questioner to provide sufficient detail to specifically identify the creature in question.

  • Generalizations such as "Elves as commonly found in fantasy stories" or "vampires" (without further clarification) are unacceptable and grounds for closing the question as "Unclear what you're asking."

  • Links to specific examples of the creature in question are encouraged, but may not be used alone. A specific description of the creature is required or the question will again be closed as "Unclear what you're asking." An ambiguous or insufficient description may result in closure due to the question becoming "Primarily opinion-based."

  • Images of the creature are always appreciated. If possible, reduce large images to a width of 450 pixels and link the image to a larger version. As with links, images may not be used alone. A specific description is required to avoid closure.

  • Creature descriptions must include important behavioral attributes and a clear physical description. It is the questioner's responsibility to invent the creature and the privilege of participants to explain how that invention could be manifest with evolutionary believability. To coin a phrase, We're willing to help, but we will not invent the creature and summon it into this world for you.

  • This question writing guide was developed long after the first AC question was asked. While we encourage questioners to review earlier AC questions to better understand how to meet these requirements, the fact that some previously asked questions do not meet these expectations may not be used to justify a poor question.

The best answer is expected to be the one that provides the greatest detail, the greatest creativity, and the greatest capacity for suspension of disbelief.


If you have come to comment on a recent Anatomically Correct post that needs to be added, please post that on the community answer, or I will not see it. Also, the question cannot have been closed within a week of posting because of being off-topic or a duplicate.

    $\begingroup$ Er...why "anatomically" correct? Aren't these just "scientifically correct"? "Anatomically" doesn't mean "evolutionarily", and "anatomically correct" typically means "including genitalia, nipples, etc." (E.g. there's a line in Batman & Robin making light of the infamous "bat-nipples" on the costumes in that movie: "an anatomically correct rubber suit puts fire in a girl's...lips.") $\endgroup$ Commented Dec 2, 2015 at 22:50

    $\begingroup$ ...and if you haven't seen that film but have heard how terrible it is, and you've wondered if it can possibly be as bad as people say, that line should tell you all you need to know. $\endgroup$ Commented Dec 2, 2015 at 22:51

    $\begingroup$ @KyleStrand: "anatomically correct" does usually refer to sex organs, but can also refer to any other part normally depicted in an unrealistic manner. For example, typing "anatomically correct" in Google gives me "... heart" as the fourth suggestion. ("... baby dolls" is the first suggestion, and creepy images related to that search show up as you're typing. You might not want to try this at home.) $\endgroup$

    $\begingroup$ That response doesn't actually make much sense. Your question indicates that what you mean is "realistic evolutionary" creatures, but that is not what "anatomically correct" means. "Anatomically correct" does not seem to mean what you think it means. $\endgroup$ Commented Jan 25, 2016 at 21:02

    $\begingroup$ @KyleStrand anatomically correct means one of two things; (1) referring to correctly sexual organs in dolls OR (2) a part of a creature correctly placed and existing. These questions use the second meaning. $\endgroup$

    $\begingroup$ But you're not talking about "a part of" a creature. You're talking about the entire creature designed in such a way as to conform to all kinds of scientific principles, including but not limited too anatomy. $\endgroup$ Commented Jan 25, 2016 at 21:09

    $\begingroup$ @KyleStrand good point, but I am not going to change it, so either be angry over a slight term that doesn't matter, or accept it. Your choice, I am not arguing this anymore. $\endgroup$

    $\begingroup$ I'm not angry, I'm just trying to help you use a correct term (I even suggested an obvious one, "scientifically correct") instead of a silly and incorrect one. Clearly you're not open to suggestions, which I suppose is fine. $\endgroup$ Commented Jan 25, 2016 at 22:30

    $\begingroup$ Er... same difference. If you're not willing to change the phrase, then by definition you're not open to change suggestions. But I thought you were not going to argue the point any more? In any case, if the time required to make the change is the only thing holding you back from doing so, you could ask for help. Suggested edits to your question & answer here on meta aren't permitted, though, so you'd have to change these yourself. $\endgroup$ Commented Jan 25, 2016 at 22:39

    $\begingroup$ why not just tag them as anatomically-correct? It's the sort of thing that seems to come up enough--to a lurker like me--that it wouldn't be crazy to have a tag for it. $\endgroup$

    $\begingroup$ That whole series irks me because the anatomy of a species is directly shaped by the species itself. So for instance "Anatomically correct human" means "A human that has all their organs, limbs and other bodily structures at pretty much the same lengths, widths and proportions as humans in general". Now translate that to every other species in this series. How would we know if one particular unicorn is "anatomically correct"? By comparing him to every other unicorn and see if he matches. Right.... so where are all our other unicorns to compare with? Uhm... $\endgroup$

Only I can edit the current program, i.e. keep it's record of the entries up to date, but anyone else can make a spin-off and have their own version if I drop off the face for any reason. Numbering can be pasted or ignored (it is cleaned from the entry text anyway when sorting). The answer does not disturb the linkages/enumeration in the original answer and the program also leaves those intact. So three step update, paste the links below, paste the entries to the program, sort, paste the list over the one below. $\endgroup$
