The image is an underwater photograph of a coral reef. The water is clear and the sand is a light beige color. The reef is covered in small rocks and coral reefs. In the center of the image, there is a large sea urchin with black and white stripes on its body. Surrounding the urchins, there are several small fish swimming around it. The fish are of different sizes and colors, including black, white, and yellow. There are also a few coral reefs visible in the background. The image appears to be taken from a low angle, looking up at the reef.
