What is the rarest devil fish in Sea of Thieves?

Excuse me, but I'm curious about something related to the game Sea of Thieves. Can you tell me, what exactly is the rarest devil fish that one can encounter in the game? I've heard rumors about some rare creatures in the game's vast ocean, and I'm particularly fascinated by the idea of a rare devil fish. Do you know which one is considered the most elusive and difficult to find?
