About 1,500 species of starfish or sea-stars are found on the seabeds of all the world's oceans, from the tropics to frigid polar waters. Many species are brightly colored in various shades of red or orange, while others are blue, grey or brown. Starfish have a mouth at the center of the oral (lower) surface. I wanted to show a pattern from this seldom-seen side of the starfish. Photo: 105mm macro lends; Banda Sea, Indonesia.
