Basically every sea monster cryptid. There's so much shit down there we don't know about. Guarantee many many many of them are over exaggerated yes but there has been more than one case of a sea monster cryptid turning out to actually just be a real creature. Fucks me up
Well the current collosal squids we see aren't exactly boat crushers. They are big but not THAT big yk? Still definitely the inspiration for the legend but not as true to form as the oarfish was
I just noticed I used giant squid instead of collosal squid that's on me
