Biology is a natural science concerned with the study of life and living organisms. With regards to science fiction and fantasy works, it is generally associated with the practicalities of invented forms of life or life-supporting habitats.
Biological questions on science fiction and fantasy are usually related to either
- how a given creature or being from a science fiction or fantasy property would work in real life, or
- how a real life human or being would work in the setting of a science fiction or fantasy property.
If your question is about real-world biology, your question is off-topic here. You might consider asking on the Biology Stack Exchange.
