The bathypelagic zone, also known as the midnight zone, extends from a depth of approximately 1,000 meters (3,280 feet) to about 4,000 meters (13,123 feet) in the ocean. In this zone, sunlight does not penetrate, resulting in complete darkness and cold temperatures. It is home to a variety of organisms adapted to high pressure and low light conditions, such as bioluminescent creatures.

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.
A depth of 3,500 meters is equivalent to 3.5 kilometers. In terms of ocean depth, this is significantly deeper than many parts of the ocean, placing it in the bathypelagic zone, where light penetration is minimal and pressure is extremely high. This depth can be found in various oceanic trenches and is home to unique ecosystems and organisms adapted to such extreme conditions.
The names Epipelagic, Mesopelagic, and Bathypelagic refer to distinct layers of the ocean defined by depth. The Epipelagic zone, also known as the sunlight zone, extends from the surface down to about 200 meters, where sunlight penetrates, supporting photosynthesis. The Mesopelagic zone, or twilight zone, ranges from 200 to around 1,000 meters, where light diminishes and temperatures drop. The Bathypelagic zone, or midnight zone, spans from 1,000 meters to about 4,000 meters deep, characterized by complete darkness and high pressure, where most organisms rely on bioluminescence for communication and predation.
The open ocean of any depth is called the pelagic zone. This zone encompasses all the water in the ocean that is not near the shore or the ocean floor. Within the pelagic zone, there are different regions based on depth and light penetration, such as the epipelagic, mesopelagic, bathypelagic, and abyssopelagic zones.
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.
The first exploration of the Bathypelagic zone, which ranges from about 1,000 to 4,000 meters deep in the ocean, occurred during the late 19th century. Notably, the HMS Challenger expedition from 1872 to 1876 provided significant insights into deep-sea environments, including the Bathypelagic zone. This expedition collected valuable data on marine life, sediment samples, and oceanographic conditions, marking a pivotal moment in ocean exploration.
Sunlight can reach through all the zones of the ocean, including the epipelagic (sunlight zone), mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic zones. The intensity of sunlight decreases with depth, so the amount of light available for photosynthesis decreases below the epipelagic zone.

Words with the root "bathy" typically relate to depth or deep places. For example, "bathysphere" refers to a spherical deep-sea diving vessel, while "bathymetry" is the measurement of the depth of oceans, seas, or other bodies of water. These words are commonly used in oceanography and geography to describe the study and exploration of deep underwater environments.
