Seen this kind of fish before? Never say yes because you haven't. This is the Pancake Batfish that lives in the Gulf of Mexico and some part of Louisiana. Check out the description below.

Pancake batfish—such as the new species Halieutichthys intermedius —are so named because they're flat and can use their stout, armlike fins to shamble along the seafloor with a stilted gait, reminiscent of a walking bat.
H. intermedius lives in only the Gulf of Mexico, including parts—such as coastal Louisiana—that were heavily affected by the 2010 Gulf oil spill. The fish's status in the Gulf a year later is unknown.
