A hyper-realistic underwater scene shows a mermaid, 23 years old, gliding at full speed, just above the ocean floor, at a depth of six to seven meters, surrounded by natural rock formations and coral, her deep copper-red hair flowing behind her, catching the light as she moves, adorned with sparkling diamond, opal, and turquoise stones that complement the turquoise water and match her shimmering, iridescent tail. Her skin has natural texture, and her green eyes are focused ahead. In the background, hidden behind a large coral outcrop, approximately several meters away, well-built, tanned, blonde European snorkeler, a 30 years old, peers out, also deep underwater, holding onto the coral edge, wide eyes shocked behind his snorkel mask, He gapes his mouth wide in astonishment and loses the snorkel, as he watches the mermaid pass, unsure if she noticed him. The water surface is not visible, as this entire scene is immersed deep below, focusing solely on the underwater world, vibrant coral and rocks framing the scene, the mermaid’s motion creating gentle currents, while the snorkeler’s presence adds a hidden human element in the background
