The term deep sea creature refers to organisms that live below the photic zone of the ocean. These creatures must survive in extremely harsh conditions, such as hundreds of bars of pressure, small amounts of oxygen, very little food, no sunlight, and constant, extreme cold. Most creatures have to depend on food floating down from above.
These creatures live in very harsh environments, such as the abyssal or hadal zones, which, being thousands of meters below the surface, are almost completely devoid of light. The water is between 3 and 10 degrees Celsius and has low oxygen levels. Due to the depth, the pressure is between 20 and 1,000 bars. Creatures that live hundreds or even thousands of meters deep in the ocean have adapted to the high pressure, lack of light, and other factors.

Famous quotes containing the words deep, sea and/or creature:
“Who knows whither the clouds have fled?
In the unscarred heaven they leave no wake,
And the eyes forget the tears they have shed,
The heart forgets its sorrow and ache;
The soul partakes the season’s youth,
And the sulphurous rifts of passion and woe
Lie deep ‘neath a silence pure and smooth,
Like burnt-out craters healed with snow.”
—James Russell Lowell (1819–1891)
“It is the time we have now, and all our wasted time sinks into the sea and is swallowed up without a trace. The past is dust and ashes, and this incommensurably wide way leads to the pragmatic and kinetic future.”
—John Ashbery (b. 1927)
“I am nothing but a miserable, crushed worm, whom no one wants, whom no one loves, a useless creature with morning sickness, and a big belly, two rotten teeth, and a bad temper, a battered sense of dignity, and a love which nobody wants and which nearly drives me insane.”
—Sophie Tolstoy (1844–1919)
