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.
