Below the mesopelagic zone it is pitch dark. This is the midnight (or bathypelagic zone), extending from 1,000 metres (3,281 ft) to the bottom deep-water benthic zone. If the water is exceptionally deep, the pelagic zone below 4,000 metres (13,123 ft) is sometimes called the lower midnight (or abyssopelagic zone). Temperatures in this zone ...

Little else is known of their reproduction: They are presumed to not be guarders, releasing buoyant eggs into the water which become part of the zooplankton. While adults have been trawled from as deep as 3,000 m (9,900 ft), larvae appear to remain in the upper 100 m (330 ft) of the water column and gradually descend with maturity. Males likely ...
Due to low mixing rates between the above seawater and the brine water, brine-pool water becomes anoxic within the first ten centimeters or so. [41] While there are large variations in the geochemical composition of individual pools, [ 41 ] as well as extreme chemical stratification within the same pool, [ 42 ] conserved chemical trends are ...
Two illuminated Psalters, the Queen Mary Psalter (British Library Ms. Royal 2B, vii) and the Isabella Psalter (State Library, Munich), contain full Bestiary cycles. The bestiary in the Queen Mary Psalter is found in the "marginal" decorations that occupy about the bottom quarter of the page, and are unusually extensive and coherent in this work.
