Underwater landscape. This is called the “euphotic zone.” Ninety percent of ocean life lives here, including ALL the ocean plants. The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth. Many varieties of sea vegetation thrive to depths to about 600 feet (183 meters) in the so-called “euphotic zone.”. The majority of plants can only live in water that's shallow enough to let in sunlight, which they require for photosynthesis, the process by which plants produce nutrients.
