This image depicts an interior view of an underwater viewing tunnel at The National Aquarium, located in Al Qana, Abu Dhabi, United Arab Emirates. The upper two-thirds of the frame reveal a vast aquatic environment, predominantly blue-green in tint, with visible light rays penetrating the water from an unseen source above. Within this environment, numerous marine animals are visible: at least five large rays, characterized by their flat, broad bodies, are present, including a prominent light-colored ray in the lower-left foreground. Dense schools of smaller fish populate the mid-ground and background. The lower one-third of the image features a man-made tunnel structure with a semi-circular, transparent ceiling and walls, through which the aquarium habitat is observed. Two parallel escalators are positioned within this tunnel, descending downwards. Two human subjects are visible on the right-hand escalator, both facing forward. The lead individual wears a dark long-sleeved top. The second individual, positioned behind, wears a light-colored jacket over a dark shirt. The tunnel's interior is illuminated by multiple square, recessed light fixtures on the ceiling.
