WebFast Facts. The area between 200 and 1,000 meters is the mesopelagic or “twilight” zone. Light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal. Mesopelagic organisms have an interesting variety of mechanisms that help them find food as well as avoid being meals for other species. The mesopelagic zone has some unique acoustic features.
