When I was a kid, because tuna came in tiny little cans at the store I thought they were these small, crappy little fishes. But then my family got cable and I was introduced to a wonderful little channel called Discovery and my world was changed forever.

Not only did we experience 48 new channels just as Shark Week was beginning (I know, all cable TV was crap in comparison after that) I learned that Tuna fish were enormous, muscly creatures.

And the jacked-as-hell fish kept surprising me more and more when years later I saw footage online of Tuna auctions. These fish sell for a crap-ton of money.

But I don't think I've ever heard of a single fish being sold for $636,000, like this monstrous Tuna that was just purchased by the "Tuna King".

Sure, the guy has a name that makes him sound like the villain of a children's cartoon series, but Kiyoshi Kimura's winning bid just made him the proud owner of a 467 pound fish he'll be cutting up and using across his 51 sushi chains.

That's right, this big monster is going to be in Sushizanmai chains all across Japan, but it's not really cost effective for him to do so.

Technically speaking, he paid $85 per $3.40 he'll earn at his stores, but the amount of publicity he'll be getting for winning the auction could bring in a lot more business and exposure, so the winning bid was basically Kimura paying for advertising.

This isn't even the most he's paid for a fish, back in 2013 he shelled out $1.3 million for a rare bluefin Tuna.

Kimura has a history of being the winning bidder at these fish auctions and makes headlines pretty much everytime he takes home the biggest fish. Heavy lies the Tuna King crown, I guess. (h/t abs cbn news)
