THE NATIONAL GEOGRAPHIC MAGAZINE "SOFT" CORALS RESEMBLING GIANT WARTS BASK IN A GARDEN OF SEAWEEDS Expansive surfaces of the alcyonarians are finely pitted and leathery in texture, with convoluted or folded edges. These creatures are unable to develop the lime which gives the hard coral its rigid supporting skeleton. NOT A PURPLE CHRYSANTHEMUM, BUT A SEA ANEMONE These "flowers" of Great Barrier Reef really are animals. Dainty "petals" are tentacles, reaching out for food. Soft and fleshy bodies, usually cylindrical in shape, anchor themselves to the surface of rocks.
