Cloud Mantas: Ranging from the size of a large dinner plate to a wingspan nearly six feet across, cloud mantas have flattened, ray-like bodies, narrow, delicate heads with two large dark eyes, and flowing-finned tails that are reminiscent of betta fish or scallop-edged leaves. They are equally comfortable underwater and flying through the air, and often travel in groups of 5 to 20, depending on size of individuals. The species varies in shades of blues and grays with paler underbellies, but most notable are the large green splotches across the upper surface of their bodies and 'wings' which are filled with chlorophyll and photosynthesize both food and oxygen for the creatures. Gentle and graceful, these plantimals also make meals of mosses and lichens, scraping them off rocks near water with small mouths located on the underside of their heads. As a cloud manta ages a colorful crystal grows in the middle of its forehead, comprised of excess minerals that it purifies out of its body. If worn pressed against the throat in a choker or collar, these crystals are said to allow someone to breathe underwater.
