This stack exchange is about worldbuilding. Specifically it is for making sure that the features of your world are sensible and realistic/logical. I assumed that this purpose included asking for the function of interesting-looking features that you'd like to use in your worlds. The main reasons I had were:
- This is a rather fact-based query. It in fact is the only way we know what the function of bodyparts are
- It is a common way to worldbuild, especially with fantasy, where taking creatures from mythology is rather common
- A lot of other questions do it
But I have been made aware that these questions are somehow off-topic, because there are other questions that come up with things the other way round or something like that
Can we clear up the rules in this area?
