We've got some seriously bad news for fish-lovers. According to a report from nonprofit Oceana, over 20% of 449 fish that they tested were mislabeled, exposing some pretty serious "fish fraud." This is a staggering percentage, especially when considering that less than 1% of fish is tested for fraud. There's a huge chance that the expensive fish you're ordering while dining out is cheap - or even, according to this related Twitter thread from a biology professor, dangerous. There are fish out there that will hurt you to eat. And, as @AwesomeBioTA's class discovered, some of this "fish" is almost too disgusting for words.
