Former Cryptids are cryptids that have been scientificaly proven to exist
When we think of cryptozoology, we usually think of Sasquatch, the Yeti, and the Loch Ness Monster, creatures that, despite so many years of searching, remain hidden. But some cryptids have been found, like the Okapi, the Gorilla, the Kraken, and many, many more.
The fact is that all these creatures were not so long ago considered the stuff of myths and hoaxes by serious zoologists, and that something like the platypus was considered even less unlikely than something like a plesiosaur in Loch Ness, or an undiscovered ape wandering the Pacific Northwest. These are all real creatures that, at least for a moment, blurred the line between zoology and cryptozoology.
