…aka Oilfish aka the “It” Fish aka Shiro Maguro aka Abura Bozu aka Abura Sokumutsu aka Mutzu. I have finally found a fish that Japanese won’t eat (raw, at least), and is in fact prohibited to be used for that purpose in Japan, and it turns out it’s all because eating it may make orange jets of oil (specifically, indigestible wax esters) shoot out of your ass. And yes, I speak of that as a bug, not a feature.
