Adinary Nuance

Pelagic zone is more specific than ocean or sea. It means the open-water area, not the coast, beach, or seafloor. It is different from deep sea, which focuses on great depth rather than the open water itself. Writers use pelagic zone in science or geography, not in everyday conversation.
