The constraints of darkness, high pressure, cold temperatures, and large distance from the base of the food chain (plankton, which require sunlight) limit the amount of life that the bathypelagic zone can support. The sunlight zone, the twilight zone, the midnight zone, the abyss and the trenches. Both of these limits are variable, but the bathyal zone is generally described as lying between 200 and 2,000 m (660 and 6,600 feet) below the surface.
