Conquered from the deep sea? A new deep-sea isopod species from the Antarctic shelf shows pattern of recent colonization.
The Amundsen Sea, Antarctica, is amongst the most rapidly changing environments of the world. Its benthic inhabitants are barely known and the BIOPEARL 2 project was one of the first to biologically explore this region. Collected during this expedition, Macrostylis roaldi sp. nov. is described as th...
