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:
“These, and such as these, must be our antiquities, for lack of human vestiges. The monuments of heroes and the temples of the gods which may once have stood on the banks of this river are now, at any rate, returned to dust and primitive soil. The murmur of unchronicled nations has died away along these shores, and once more Lowell and Manchester are on the trail of the Indian.”
—Henry David Thoreau (1817–1862)
“The fact that we are all trained to be mothers from infancy on means that we are all trained to devote our lives to men, whether they are our sons or not; that we are all trained to force other women to exemplify the lack of qualities which characterizes the cultural construct of femininity.”
—Andrea Dworkin (b. 1946)
“The future author is one who discovers that language, the exploration and manipulation of the resources of language, will serve him in winning through to his way.”
—Thornton Wilder (1897–1975)
