The monkfish (pictured below) is definitely one of the most hideous looking fish in the ocean. But, if you frequent posh seafood joints, you might know that monkfish meat is very expensive and very delicious thanks to its lobster-like texture. It's not unheard of for a recreational angler to reel up one of these beasts while dropping on a wreck, but for the most part, monkfish live in water so deep that a baited hook rarely gets in front of them. Why then are researchers capturing monkfish with tiny seabirds called Dovekies in their stomachs? Because no matter how much you think you know about fish behavior, you don't know everything, and there are no hard-and-fast rules to feeding behavior.
