caption: The image shows a large brain coral on the bottom of the ocean, surrounded by a variety of sea plants and other marine life. The coral is a vibrant green color, and its tentacles are spread out around it, giving it a unique texture. The sea plants are a mix of colors, including blues, greens, and yellows, and the other sea life is a mix between blues, purples, and pinks. The sun's rays are reflecting off the coral, creating a beautiful sparkle in the water.
