An underwater view captures a dolphin swimming in a tank at the Varna Dolphinarium in Varna, Bulgaria

An underwater view captures a dolphin swimming in a tank at the Varna Dolphinarium in Varna, Bulgaria. A light-colored dolphin, likely a bottlenose, is partially visible in the left-center of the frame, moving horizontally from left to right. Its head, featuring a prominent rostrum and eye, is distinct, with motion blur evident on its body and fins. The tank's water is a clear teal color. Three distinct circular white lights are observed in the upper-mid section of the image, appearing as light sources or reflections within the tank. The transparent viewing panel exhibits multiple scratches and surface imperfections. To the far left, a dark vertical structural pillar is partially visible. Through the water and the tank's glass, reflections and views of the external environment are apparent. These include what appear to be windows, beyond which blurred natural elements such as bare trees and distant green foliage are discernible, indicating an outdoor setting beyond the facility's interior. Architectural details, possibly indoor awnings or ceiling structures, are also reflected or visible in the upper background. The bottom foreground consists of a dark, textured surface, likely a viewing platform or floor.
