In a sense, many cryptozoology stories seem to be close to mythology - some have supernatural angle (yet, admittedly, not all or even not most). And the "real, ontopic" myths themselves are full of cryptids (Nemeian Lion? Ruuh bird? Phoenix?)
Should cryptozoology stories (e.g. Nessie? Yeti? Chupacabra? etc...) be on-topic? If so, within what constraints?
