The image is an underwater photograph of a coral reef. The coral reef is covered in various shades of pink, orange, and green, with various types of sea anemones and other marine life scattered throughout. In the center of the image, there is a small white and pink sea slug with black spots on its body. The slug is resting on a bed of green algae and rocks. The background is dark, making the colors of the coral reef stand out even more. The image appears to be taken from a low angle, looking up at the slug.
