Because every zone of the ocean has the combination of the organisms living there that are adapted to the light, pressure, and temperatures. About ¾ of the ocean is very dark and cold, and very deep.

Under 200 meters is the second zone of the ocean, called the twilight zone, where the sun almost doesn’t get. The temperature in this zone is changing depending on the wind, but the most often the temperature is very low.
Under 1000 meters, there is the third zone called deep ocean, very dark and cold.
