<P> The abyssal zone or abyssopelagic zone 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 ( 13,000 to 20,000 ft ) , this zone remains in perpetual darkness . These regions are also characterized by continuous cold and lack of nutrients. The abyssal zone has temperatures around 2 to 3 ° C ( 36 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 ; 750 atm ) . </P>
