It's a... bird?
From National Geographic magazine:
"A trick of light seems to give an extra pair of feet to this phalarope bird, seen from below the water."The photo was taken by Bates Littlehales, a staff photographer for the National Geographic Society for 37 years, who is now a nature photographer.
