Lack of Resources
At this depth, there is not enough light for photosynthesis to occur and not enough oxygen to support a fish with a high metabolism. To survive, creatures have much slower metabolisms and therefore can survive using less oxygen. They can also go for months without food. Most food either comes from organic material that falls from above or from eating other creatures that have derived their food through the process of chemosynthesis (the process of changing chemical energy into food energy). Because of the sparse distributions of creatures, there is always at least some oxygen and food. Also, instead of using energy to search for food, these creatures use particular adaptations to ambush prey.

Famous quotes containing the words lack of, lack and/or resources:
“I leave the governor’s office next week, and with it public life ... [which] has been on the whole a pleasant one. But for ten years and over my salaries have not equalled my expenses, and there has been a feeling of responsibility, a lack of independence, and a necessary neglect of my family and personal interests and comfort, which make the prospect of a change comfortable to think of.”
—Rutherford Birchard Hayes (1822–1893)
“The theater is a baffling business, and a shockingly wasteful one when you consider that people who have proven their worth, who have appeared in or been responsible for successful plays, who have given outstanding performances, can still, in the full tide of their energy, be forced, through lack of opportunity, to sit idle season after season, their enthusiasm, their morale, their very talent dwindling to slow gray death. Of finances we will not even speak; it is too sad a tale.”
—Ilka Chase (1905–1978)
“We live in a time which has created the art of the absurd. It is our art. It contains happenings, Pop art, camp, a theater of the absurd.... Do we have the art because the absurd is the patina of waste...? Or are we face to face with a desperate or most rational effort from the deepest resources of the unconscious of us all to rescue civilization from the pit and plague of its bedding?”
—Norman Mailer (b. 1923)
