Which is right for you?
Choose Cryptozoology if…
- Weighing blurry eyewitness accounts for what is plausible sounds fun.
- You are fine if honest debunking feels as good as a real mystery.
- You can sit with an open question and not need it to resolve.

Before you commit
Cryptozoology
- Wanting something real while honestly debunking it would frustrate you.
- Most leads dissolving into misidentified bears would feel like a letdown.
- You want fieldwork, not hours reading sighting reports at a desk.
Speculative Biology
- Nobody seeing the years of logic behind one drawing would deflate you.
- You want a tangible result, not notebooks and tab-stacks of evolutionary logic.
- Starting a design over because the biology doesn't hold would frustrate you.
