You know your hand is in front of your face, but you don't see anything. You strain your eyes as hard as you possibly can. You wait as long as you can for you eyes to adjust for the light. Unfortunately that will do no good. You are in the area of the ocean waters underneath the area referred to as the photic zone. The rays of sunlight only go so deep in the water. The area that sunlight does exist is known as, and earlier mentioned, the photic zone. The photic zone ends, approximately, two hundred meters from the surface of the ocean. The blue spectrum of light might be fairly present, because that spectrum is so thin, but more than likely the water is to a point of darkness incomprehensible to most people.
We know there are fish, plants, mammals, bacteria, and all other sorts of organisms living in the sea, but they, for the most part, live in the luminescent part of the ocean waters.

It is understood that plants make their own food by using sunlight, or way of photosynthesis. Excuse the sarcasm, but "Is it possible to utilize photosynthesis without sunlight?" I seriously doubt it. So what do these creatures of the depth do for food the bacteria and plants all use sunlight to live? Another problem living this deep in the water is the incredible amount of pressure. In the depths of the ocean the pressure increases at fifteen pounds on every square inch for every thirty feet that one descends (Perry, 63). For an example the pressure below the photic zone is about one hundred pounds per square inch, and...
