UNDERSEA GARDENS OF THE NORTH ATLANTIC COAST © National Geographic Society Painted by Else Bostelmann under direction Roy W. Miner UNDER A MAGNIFYING GLASS, A SEA WORM METROPOLIS RISES ON A TINY PEBBLE Petal-like breathing organs give the SEA DIANTHUS (foreground) the appearance of a spreading flower head. Each plume has tiny eyes so sensitive to light that, when a shadow passes, the "flower" pops into the tube. Crowned with golden "piano keys," SAND BUILDERS (upper and lower left) carefully wall themselves in with sand grains. Grayish tentacles protruding like "whiskers" are covered with a sticky substance that catches bits of food. Shells of thousands of BRYOZOA, or MOSS ANIMALS, and HYDROIDS blanket the background. SWALLOW-TAIL PROTOZOA extend Y-shaped lappets (lower right).
