The bathyal zone is the part of the ocean that extends from the edge of the continental shelf down to the abyssal plain. It's like the twilight zone of the sea, where sunlight barely penetrates 🔦. Unlike the sunlit surface, it's a dark and cold environment. It's a region of steep slopes and unique marine life. Think of it as the mysterious middle ground between the shallow and deep ocean. Organisms here have adapted to the extreme conditions.
