Investigating Adaptation of Antarctic Worms to Warming Oceans
23.12.2011
University of Delaware researchers are currently studying how tiny worms living in the freezing sea off the coast of Antarctica have adapted to such an extreme environment as well as how they might survive as the ocean worms. Adam Marsh and colleagues from the University of Delaware’s College of Earth,…
