Biologists have explored the genetic mechanisms underlying the transition from freezing Antarctic waters to more temperature waters by Antarctic Notothenioid fish. Many animals have evolved to ...

Researchers reporting in the journal Current Biology on January 13 have discovered a massive breeding colony of notothenioid icefish in Antarctica's southern Weddell Sea. They estimate that the colony ...

Antarctic fish have built a sprawling neighborhood of neatly arranged nests in the Weddell Sea — a surprising display of organization in some of the coldest waters on Earth. The discovery suggests ...

Antarctic notothenioid fishes inhabit the Southern Ocean at sub-zero temperatures and experience one of the highest dissolved oxygen concentrations of any marine habitat. While this environment ...

Many animals have evolved to tolerate extreme environments, including being able to survive crushing pressures of ocean trenches, unforgiving heat of deserts, and limited oxygen high in the mountains.
