This “walking” rock sole fish has an unusual way of moving. Flatfishes, including flounder, sole, and halibut, live on the seafloor and eat small bottom-dwelling animals. To move forward, flatfish bunch up a few fin rays to form a “fin-foot.” In a wavelike sequence, the “feet” move the fish across the seafloor. The movement is just one way these fishes have adapted to life on the seafloor.
