"While Komodo Island, Indonesia is famous for its giant prehistoric lizard, its underwater also holds unique marine species to treasure. The orangutan crab is one of them. With its maximum size of two centimeters, it felt like searching for a needle in a haystack just to find him," wrote Indah Susanti of her image, a winning selection in the Portraits of Planet Ocean Flickr contest. Orangutan crabs (Achaeus japonicas) are covered in thin reddish hairs, and are frequently found living in bubble coral (Plerogyra sinuosa), as seen here. See more winning photos.
