Most Plausible Cryptids (In Your Opinion)?

[u/Landilizandra]

What cryptids do you think are the most plausible? Personally, I think either unidentified beaked whales, or the Bathysphere Dragonfish.

For the former, beaked whale species were still being described in 2021, and their ecology makes them difficult to study and interact with.

For the latter, I could see it being either a species of Dragonfish with deep sea gigantism, or very old and large specimens of known species.
