The deepest layer of the earth's oceans gets no sunlight at all. This dark ocean layer is called the midnight zone or the aphotic zone (aphotic means "no light" in Greek). The depth of this zone depends on the clarity or murkiness of the water. In clear water, the aphotic zone begins at depths of about twenty anxiety; in murky water, it starts around twenty feet. It is usually somewhere between these 2 extremes. On boilerplate, the depth of the ocean is about thirteen,000 feet (4,000 k).
Temperature is near freezing and decreases with depth.
Pressure is extremely high and increases with depth.
Bioluminescence (light generated by living things) is the only light seen in this zone.

The aphotic zone is divided into two parts- the bathyal zone and the abyssal zone. The bathyal zone extends from 200 meters to 2000 meters. The deep-sea zone extends from 2000 meters to the bottom; the exact level of the zone depends of how murky or cloudy (turbid) the water is. Creatures in this area must be able to live in complete darkness and in close to freezing h2o.
In the aphotic zone, in that location virtually no light from the sun (1% or less of sunlight reached this zone), so photosynthesis can non take identify. Consequently there are no plants or other photosynthetic organisms in this zone. The only food/energy sources in this zone is from organic matter in the water column (plants and animals floating downward from college zones).
Animals:
Examples of aphotic zone animals include algae, anemones, anglerfish, arrow worm, cookie-cutter shark, copepods, crabs and other crustaceans, ctenophores, dinoflagellates, fangtooth, lanternfish (Myctophids), mussels, nudibranchs, some squid (like the vampire squid), segmented worms, siphonophores, swallower fish, tripod fish, tubeworms, pelican eel, umbrellamouth gulper, vampire squid, and viperfish.
