What zone is known as the midnight zone?

• A. Twilight zone
• B. Bathypelagic zone
• C. Midnight zone
• D. Abyssopelagic zone

Answer: (B)

In ocean depth zones, the midnight zone refers to the completely dark layer below the part of the ocean where some light still filters through. This darkness defines the bathypelagic zone, which runs roughly from 1,000 to 4,000 meters below the surface. With no sunlight reaching these depths, the environment is cold and under high pressure, so most organisms here rely on energy that sinks from above or on bioluminescence to find prey or mates. That combination of no light and this depth range makes the bathypelagic zone the Midnight zone. The twilight zone is shallower and only dimly lit (mesopelagic), and the abyssopelagic zone is deeper still, beyond the bathypelagic.
