Polychaetes in the Southern Ocean are often thought to have wide distribution ranges on a horizontal and vertical scale. Here, this theory is tested for specimens commonly identified as the widely distributed glycerid Glycera kerguelensis using two molecular markers, the mitochondrial cytochrome oxidase c subunit I (COI) and the nuclear 28S rDNA.

The genus Terebellides is, despite its often low abundances, a common and diverse element of benthic, soft sediment communities at all depths. In recent years, careful examination of specimens has resulted in numerous descriptions of new species of Terebellides increasing the number of species in the genus to over forty. For the Southern Ocean currently(More)
The richness of life in parts of the earth that to us appear inhospitable and remote never fails to fascinate scientists and non-scientists alike. The largest ecosystem of the planet, the abyssal plains of the world ocean, makes up about 90 percent of the seafloor and thus nearly 78 percent of the Earth’s surface, yet only a minor fraction of this huge(More)
