As the sun’s rays penetrate the ocean’s surface, they illuminate a vibrant world teeming with life. This sunlit layer, known as the euphotic zone, stretches from the sea’s surface down to 200 meters and is often referred to as the ocean’s “rainforest” due to its rich biodiversity.
In these warm waters, countless marine creatures thrive by harnessing sunlight for photosynthesis. Schools of juvenile black and white snappers dart among the coral reefs, shimmering in the sunlight. Moray eels slink through underwater crevices, while an array of unimaginable marine life in diverse colors and shapes flourish in this sun-drenched environment.
Off the coast of Lingshui, a coastal county on Hainan Island in southern China, the euphotic zone reveals an astonishing underwater paradise. Lingshui is renowned for its beautiful beaches, clear waters, and abundant marine life. The region’s warm sunshine not only nurtures the coral reefs but also supports a vast array of species that depend on this delicate ecosystem.
Exploring the sunlit depths of the euphotic zone offers a glimpse into the complex and vibrant communities that exist beneath the waves. From the tiniest plankton to larger sea creatures, each plays a crucial role in maintaining the health and balance of the ocean’s “rainforest.”
Preserving this underwater world is essential for maintaining biodiversity and supporting the livelihoods of communities that rely on the sea. Conservation efforts in regions like Lingshui are critical to protect these rich marine habitats for future generations.
