The image depicts an underwater scene in deep blue water, characteristic of the Key Biscayne, United States, marine environment. Suspended particulate matter and numerous air bubbles are visible throughout the water column. A large, dark-bodied fish, streamlined with a distinct caudal fin, swims horizontally in the mid-frame, oriented from left to right. In the lower-left corner, a dark, indistinct shape, potentially the head and shoulder of a diver, is partially visible. Centered in the lower portion of the frame, a slender, light-colored pole extends upwards, topped by a horizontal, dark-colored fixture resembling a modern street light.
