Abyssal zone

The abyssal zone or abyssopelagic is a layer of the pelagic zone of the ocean. "Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,123 to 19,685 feet), this zone remains in perpetual darkness and never receives daylight. These regions are also characterised by continuous cold and lack of nutrients.The abyssal zone has temperatures around 2 °C to 3 °C (35 °F to 37 °F) through the large majority of its mass. It is the deeper part of the midnight zone which starts in the bathypelagic waters above. Its permanent inhabitants (for example, Riftia pachyptila, (the Giant tube worm) found near hydrothermal vents in the pacific ocean and the giant squid are able to withstand the immense pressures of the ocean depths, up to 76 megapascals (11,000 psi).
