Integrative taxonomy of a new cocculinid limpet dominating the Aurora Vent Field in the central Arctic ocean
Deep-sea hydrothermal vents host lush chemosynthetic communities, dominated by endemic fauna that cannot live in other ecosystems. Despite over 500 active vents found worldwide, the Arctic has remained a little-studied piece of vent biogeography. Though located as early as 2001, the faunal communiti...
