Animals live in constant darkness.

Explanation:

The deepest part of the ocean floor does not receive sunlight as solar radiations cannot penetrate to such depth. This part is inhabited by benthos. Since sunlight do not reach to the deepest part of the ocean floor, these organisms are adapted to live in constant darkness.

Absence of sunlight also leads to comparatively colder temperature conditions in the region.
