freaky footed fish

Since Liam loves looking at the fish for sale here (as in to be cut up and eaten fresh, fresh, fresh), we've seen pretty much every species of fish eaten in Korea. We've seen these ugly guys (not the ugliest, however, that title belongs to the Pacific Lumpsucker) around before, but just realized recently that they have FEET. What kind of crazy, mutant fish has FEET? No, that's a real question. When I google "Korea fish feet," the results I get are all for "doctor fish," the fish I wrote about yesterday which nibble the dead skin off your feet. Does anyone know what these fish are called?

(I apologize for the poor quality of the photo. The fish were in a weird-shaped tank.)
