If you haven’t caught the new, apocalypse-themed issue of Lucky Peachyou’ve got some catching up to do. One thing you’ll find is an interesting piece about sustainable fishing and the health of our oceans by Peter Meehan. He hit the high seas with Bren Smith of Thimble Island Oyster Company to find out what really goes on out there, and why fisherman are finding it harder than ever to fight the effects of climate change, overfishing, and pollution.

Unfortunately, you can only read the piece in the magazine itself, but Meehan just hit off the Lucky Peach Tumblr with an awesome web exclusive in which Smith describes some of the fucked up sea creatures he deals with on the boat.

That monstrosity you see above? Oh, that’s just an oyster toadfish, a.k.a. a bar dog: “With their sharp teeth and strong jaws, they can crunch through any oyster shell and bite to the bone if they catch your finger.” They are not considered edible, but Smith says there “two secret slices of tender white meat to be found if you know where to look.”

If you’re into odd critters of the ocean, check out the full post to learn about oyster crabs, slipper shells, and portly spider crabs.
