Definition
The bathyal district is another term for the bathyal zone, referring to the same region of the ocean between the continental shelf and the abyssal plain. It's the area where sunlight is scarce, and life adapts to the darkness. Consider it like using "district" as a fancy synonym for "zone". It's typically populated by organisms adapted to high pressure and low temperatures. It's a bit of scientific jargon that adds precision 🔬. The terms are often interchangeable.
