Shallow marine benthic communities around Antarctica show high levels of endemism, gigantism, slow growth, longevity and late maturity, as well as adaptive radiations that have generated considerable biodiversity in some taxa. The deeper parts of the Southern Ocean exhibit some unique environmental features, including a very deep continental shelf and a(More)
Benthic foraminifera are unicellular eukaryotes found abundantly in many types of marine sediments. Many species survive and possibly reproduce in anoxic habitats, but sustainable anaerobic metabolism has not been previously described. Here we demonstrate that the foraminifer Globobulimina pseudospinescens accumulates intracellular nitrate stores and that(More)
A new species of the genus Protoglossus is described from the west coast of the Scandinavian Peninsula. It lives buried in clay bottoms below the halocline where the salinity is at least 33–34 psu. Body small, estimated maximal length 1.5 cm. Collar broader than long, with a forward inclination. The thickest part is the collar region where it can be up to 1(More)
