So why has no one ever heard of it? Well, if you've ever gone fishing off the coast of Boston, you probably know Sea Robin by its more commonly used name: "Bait Stealer."

No, that's not a creature from the black lagoon or a Nordic fairy that wreaks havoc on nearby villages. It's a Sea Robin, a delicious, inexpensive, sustainable fish found throughout the Northeast.

"You're out catching flounder or black sea bass, you think you've got something, and it's a sea robin." That's how Adam Geringer-Dunn, the owner of the newly opened Greenpoint Fish & Lobster in Brooklyn, describes the sensation he felt when catching Sea Robin on childhood fishing trips. It's the annoying fish that keeps popping up when you're trying to catch something else.

The reason the Sea Robin is primarily known as an aquatic nuisance is because a lot of them aren't all that useful. "There isn't a ton of meat on them, so you really need to be getting a larger sized one for it to be worthwhile," explains Geringer-Dunn. And, while most people aren't actively trying to catch them, the larger ones are out there. Greenpoint Fish & Lobster has a direct relationship with a fisherman that recently began providing them to the shop's retail counter.

And guess what? That weird-looking thing is totally delicious. "They have little feet and walk along the bottom of the ocean," says Gerigner-Dunn. "They're eating all the same things fluke are eating, so it has a very similar flavor." That means a mildly sweet flavor, with a firm texture and a slight flakiness when cooked.

But the best part of cooking with an unsung fish is the price. Geringer-Dunn sells the fish whole for $3.99/lb or filleted for $6.99/lb. There's the sustainability factor when you go for an underfished option rather than an overfished one like tuna.

So if you're located in the North East, ask your fishmonger if they've got Sea Robin in stock or can get it. If they look at you a bit funny, just ask for Bait Stealer.
