A surreal underwater world where a dense forest of giant sequoia trees stands submerged, resembling a coral reef. The towering trees have their roots anchored to the ocean floor, and their lush canopies sway gently in the water. Vibrant marine life, including schools of colorful fish, sea turtles, jellyfish, and other aquatic creatures, thrives among the branches and foliage of the trees. Sunlight filters through the crystal-clear water, casting dramatic rays of light that illuminate the tranquil underwater scene.
