Moon Jellyfish Bloom in Sardinian Twilight Waters

Steel-blue ambient light washes over a wide panoramic expanse of the Sardinian sea during indigo twilight. Hundreds of translucent moon jellyfish float in a dense, pulsing bloom, their bell-shaped bodies glowing faintly against the deepening water. A soft haze of plankton diffuses the distance, creating layers of visibility that fade into the dark horizon. The water remains perfectly still, holding the jellyfish in a suspended state. Delicate tentacles trail beneath each translucent dome, catching the faint residual light. The surface above reflects a gradient from deep violet to black, while the jellyfish bells display subtle pink and white internal structures. One cluster of jellyfish rests near the bottom right, their edges blurring into the milky water.
