That is bizarro. The fried head is by far the best part. Lots of people don't eat them though. I don't think they realize that you are actually supposed to eat them. I've freaked a few people out when they saw me eat one in the past,,, people who were eating with me, and people sitting near me. It grosses lots of Haoles out. lol
Growing up in Hawaii,,, our neighbors on both sides of our house were locals who had like 2 or 3 generations of their families living in the house together. The Old Grandpas on both sides would go out and hand net all kinds of crap everyday,,, and they would bring EVERYTHING caught in their nets back,,, everything ... vertebrate , invertebrate, plant. They always shared with us,,, almost insisted that we ate something from them every night (they'd bring some over if we weren't outside in the backyard already). Anyway, my taste buds were allowed to run wild from that experience let's say. I enjoy FRESH seafood sooooooooo much as a result. Octopus was my favorite back then,,, and it still is today. Eating a whole shrimp head is nothing compared to some of the crazy looking stuff they snagged in those nets.
I have a favorite sushi place that's actually far from the fanciest. I've tried them all in the Central FL area, and part of the reason I like my little place the best is because they fry the heads so much better than just about anyone else.
