WebDysphotic Zone (Twilight Zone or Mesopelagic Zone) The area between 200 and 1,000 meters (656 and 3,280 feet) is the dysphotic zone. Also known as the twilight zone (or mesopelagic zone), light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal. WebThis interval from the surface to 650 ft (200 m) is therefore known as the euphotic ( “ eu- ” = good, “ photo- ” = light) zone, or simply the photic zone.
