For an animal, surviving in the ocean’s deepest trenches requires remarkable adaptations: a gelatinous body that can withstand pressure, bioluminescent features to guide it, and a transparent ...

A new study offers the first direct evidence that deep-dwelling mesopelagic fish, which account for up to 94% of global fish biomass, excrete carbonate minerals at rates comparable to shallow-water ...

Mesopelagic fish, long overlooked in ocean chemistry, are now proven to excrete carbonate minerals much like their shallow-water counterparts—despite living in dark, high-pressure depths. Using the ...

An international study led by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), Spain, has investigated how marine ecosystems responded to past ...

New research sheds light on the overlooked contribution of the ocean’s most abundant fish to marine carbon cycling. The findings open new avenues for studying deep-sea carbon dynamics and may improve ...
