The bottom of the ocean is not hospitable. There is no light; the temperature is freezing cold; and the pressure of all the water above will literally crush you. The animals that live at this depth have developed biophysical adaptations that allow them to survive in these harsh conditions. What are these adaptations and how did they develop?
