In ocean, animal masses {deep scattering layer} (DSL) rise at night and fall by day, in vertical migration.
Ocean zones {oceanic zone} include bathyal and abyssal zones.
Oceanic zones {abyssal zone} can be below 2000 meters.
Oceanic zones {bathyal zone} can be from surface down to 2000 meters.
Oceanic zones {euphotic zone} can have light.
ocean coasts and river mouths {limnetic zone}.
Continental shelf {littoral zone} can be between tides.
Continental shelf {neritic zone} can be above high tide.
