The third layer of the ocean is the Bathypelagic Zone. This is also called the dark zone. There is no sunlight in this zone, and it extends from 1,000 meters to about 4,000 meters in depth. The pressure is extremely high in this zone.
The temp. depends on the deeper you get in the ocean and which means it gets colder
The oyster/pearl oyster lives in the bathypelagic zone of the ocean.

The ocean zones are divided into five main layers: epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic. Their scientific names are based on their depth range and physical characteristics within the ocean.
Bathypelagic
The marine zone that is divided vertically by depth into three additional zones is the pelagic zone. The three zones within the pelagic zone are the epipelagic zone (0-200 meters), the mesopelagic zone (200-1,000 meters), and the bathypelagic zone (1,000-4,000 meters). These zones represent different levels of light penetration and nutrient availability.
Gulper Eels live right in the middle of the Bathypelagic Zone, more commonly known as the "Midnight" Zone, where it is black as night.
Giant Isopod (Bathynomus Giganteus) are found in most oceans of the world. Their habitat ranges in depth from dimly lit sublittoral zone of about 550 feet to the pitch darkness of the bathypelagic zone at 7,020 feet. They live olitary lives and prefer mud or clay ocean bottom areas.
