The image is an underwater photograph of a coral reef at night. The coral reef is covered in various shades of green and brown, with some areas appearing darker and others lighter. In the center of the image, there is a large rock formation with a yellowish-orange color. The rock appears to be covered in algae and other marine debris. The background is dark, making the coral reef stand out even more. The image is taken from a low angle, looking up at the rock formation.
