In between the euphotic and the bathyal zone is the twilight zone, an area that still receives some sunlight, but not enough for plants to grow. The bathyal zone (aka midnight) is the middle zone that has no light. Many zooplankton and smaller fish live here.he euphotic zone is from the surface of the ocean down 200 meters. This zone is also sometimes called the sunlight zone because there is enough sunlight to have photosynthesis. This zone has the highest levels of sunlight, photosynthesis, and dissolved oxygen. Many large predatory fish live here.
The mesopelagic zone starts 200 meters below the surface and extends to 1,000 meters (3,300 feet). The bathypelagic zone is from 1,000 meters to 4,000 meters (13,000 ft).The abyssopelagic zone is 4,000 meters and below. While most sea turtles stay in the epipelagic zone, leatherbacks have been recorded diving down into the bathypelagic zone.The upper portion of the epipelagic zone receives sunlight that drives photosynthesis in microscopic floating plants called phytoplankton.he mesopelagic zone starts 200 meters below the surface and extends to 1,000 meters (3,300 feet). The bathypelagic zone is from 1,000 meters to 4,000 meters (13,000 ft).
