PHOSPHORESCENCE IN DEEP-SEA ANIMALS

How to Keep Deep-Sea Animals

Metabolic Potential of Deep-sea Animals: Regional and Global Scales

A significant C flux into the deep-sea which is not accounted for by sedimentary flux results from the vertical transport of organic C in the bodies of zooplankton and micronekton. The energy metabolism of these animals results in the production of CO2 in these deeper waters and is a flux which is currently estimated from the differences in sedimentation at different depths. We evaluate the pos...

Deep sea in deep trouble?

Ahead of the imminent start of the industrial exploitation of deep sea resources, an EU report finds that scientific knowledge and understanding of this environment and its ecosystems still fall short of what would be needed for a sustainable use.

Distribution of polyunsaturated Fatty acids in bacteria present in intestines of deep-sea fish and shallow-sea poikilothermic animals.

The lipid and fatty acid compositions in nine obligate and facultative barophilic bacteria isolated from the intestinal contents of seven deep-sea fish were determined. Phospholipid compositions were simple, with phosphatidylethanolamine and phosphatidylglycerol predominating in all strains. Docosahexaenoic acid (DHA; 22:6n-3), which has not been reported in procaryotes except for deep-sea bact...

The red and the black: bioluminescence and the color of animals in the deep sea.

The colors of deep-sea species are generally assumed to be cryptic, but it is not known how cryptic they are and under what conditions. This study measured the color of approximately 70 deep-sea species, both pelagic and benthic, and compared the results with two sets of predictions: 1) optimal crypsis under ambient light, 2) optimal crypsis when viewed by bioluminescent "searchlights." The ref...
