The corals are of different shapes, sizes, and colors, and they are scattered across the water's surface. There are also a few small fish swimming around the corals. The image is taken from a low angle, looking up at the reef. In the bottom right corner of the image, there is a watermark that reads "Copyright 2017 CORALATIONS".
