#arch#, A vibrant underwater arch, intricately formed from living corals, sponges, and anemones. Its surface is a riot of texture, from the rough, stony feel of branching coral to the soft, pulsating undulations of sea anemones. Colors burst forth in electric blues, fiery oranges, neon greens, and deep purples, creating a dazzling mosaic. The arch appears organic and slightly asymmetrical, with feathery tentacles and bulbous growths adding to its complex, evolving structure.
