What are three adaptations that aphotic creatures have that them live in the extreme cold?

First is Light. This area in the deep sea, where there is totally no light at all. Creatures survive by producing their own light through chemical reaction, which is called bioluminescence. Second is Food. Since light cannot reach this area anymore, photosynthesis cannot take place. The creatures feed on decaying organisms.
Last is Oxygen. Aphotic region is the coldest region of the sea and have an adequate amount of oxygen.
