The water is crystal clear, allowing us to see the vibrant colors of the coral and the various shapes and sizes of the sea anemones. The coral is a mix of colors, ranging from bright pinks and purples to deep blues and greens, and the urchins are a deep brown. The sun's rays are reflecting off the surface of the water, creating a beautiful sparkle.
