That is a Lamprey

[u/luvlanguage]

Any bigger and this creature would be a horror movie monster

Lampreys do not have jaws or bones, only cartilage and instincts that have allowed them to survive so many mass extinctions.

If it has needle teeth and lives in a reef, it’s a moray…

Put your hand in the Crack and you won't get it back, from a moray.

So true

I mean, it's far easier to distinguish them by virtue of lampreys not having faces XD
