The abyssal zone is the abyssopelagic layer or pelagic zone that contains the very deep benthic communities near the bottom of oceans. "Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres, this zone remains in perpetual darkness and never receives daylight. It is the deeper part of the midnight zone which starts in the bathypelagic waters above.
