In general, the deep sea is considered to start at the aphotic zone, the point where sunlight loses its power of transference through the water.

The bottommost zone, below the euphotic zone, is called the aphotic zone.

The depth of the aphotic zone can be greatly affected by such things as turbidity and the season of the year.

The aphotic zone underlies the photic zone, which is that portion of a lake or ocean directly affected by sunlight.

Depending on how the zone is defined, the aphotic zone of the ocean begins between depths of roughly or, and extends to the ocean floor.

The aphotic zone is further divided into additional zones: the bathyal zone, the abyssal zone, and the hadal zone.

Some, such as the swallowers, can live as deep as 10, 000 feet ( 3, 000 m ) in the ocean, well into the aphotic zone.

For information on animals that live in the deeper areas of the oceans see aphotic zone.

Extending from the bottom of the photic zone down to the seabed is the aphotic zone, a region of perpetual darkness.

The off shore areas may be called the pelagic zone, and the aphotic zone may be called the profundal zone.

The vampire squid is an extreme example of a deep-sea cephalopod, thought to reside at aphotic ( lightless ) depths from 600 – 900 metres ( 2, 000 – 3, 000 feet ) or more.

The bathypelagic and abyssopelagic zones are aphotic, meaning that no light penetrates this area of the ocean.

It lies between the photic epipelagic above and the aphotic bathypelagic below, where there is no light at all.

Much of the aphotic zone's energy is supplied by the open ocean in the form of detritus.

Some species undergo diel vertical migrations of several hundred metres ; that is, they remain at aphotic depths ( below ca.
