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:
“It often happens that the real tragedies of life occur in such an inartistic manner that they hurt us by their crude violence, their absolute incoherence, their absurd want of meaning, their entire lack of style.”
—Oscar Wilde (1854–1900)
“The lack of closeness among friends is a fault that cannot be reprimanded without becoming incurable.”
—Friedrich Nietzsche (1844–1900)
“Your children don’t have equal talents now and they won’t have equal opportunities later in life. You may be able to divide resources equally in childhood, but your best efforts won’t succeed in shielding them from personal or physical crises. . . . Your heart will be broken a thousand times if you really expect to equalize your children’s happiness by striving to love them equally.”
—Marianne E. Neifert (20th century)
