The Seadragonus Giganticus Maximus, the giant sea dragon from the big dragon novel, can be a variety of colors. They are typically blue, green, or purple and are often covered in marine corals, anemones, and barnacles that act as natural armor. Some specific color varieties include deep green, pale pink and white, dark blue with red stripes and a white underbelly, dark red with tan stripes, black with a yellow underbelly, turquoise with shades of blue, yellow, and green, and many more. Their color can be as diverse as the ocean itself!
