The image presents an overhead view of a shallow marine environment in the coastal waters of Varna, Bulgaria. The water exhibits a clear, greenish-teal coloration. Multiple jellyfish are observed suspended within the water column. In the mid-left foreground, two prominent, translucent, disc-shaped jellyfish are visible, one partially overlapping the other. Each of these exhibits four distinct, symmetrical, white horseshoe-shaped internal structures, consistent with Aurelia aurita. Additional smaller, less defined jellyfish are dispersed throughout the frame. Numerous reflective air bubbles are scattered across the water's surface, particularly in the mid-right and lower-right sections. The bottom of the aquatic area is discernible along the lower edge of the image, displaying dark brown or reddish submerged aquatic vegetation, resembling seaweed, interspersed with dark, oval-shaped bivalves, likely mussels, attached to the substrate. No human presence or explicit actions are depicted.
