Thalatte

"I can’t make head nor tail nor stomach lining of it, skipper."

Thalatte are biological peculiarities that roam the depths of the Unterzee. Apparently, these creatures possess a "beaked mouth", a "hooked sucker-maw", a "double handful of maxillipeds," and an uncountable number of other mismatched organs. Their meat is also notorious for being extremely foul, and can drive a person to madness if not processed correctly. Part of this process apparently involves a full nine-hour boil.
