Prionospio Malmgren 1867 and Aurospio Maciolek 1981 (Annelida: Spionidae) are polychaete genera commonly found in the deep sea. Both genera belong to the Prionospio complex, whose members are known to have limited distinguishing characters. Morphological identification of specimens from the deep sea is challenging, as fragmentation and other damages are common during sampling. These issues impede investigations into the distribution patterns of these genera in the deep sea. In this study, we employ two molecular markers (16S rRNA and 18S) to study the diversity and the distribution patterns of Prionospio and Aurospio from the tropical North Atlantic, the Puerto Rico Trench and the central Pacific. Based on different molecular analyses (Automated Barcode... |

Because of the unique conditions that exist around the Antarctic continent, Southern Ocean (SO) ecosystems are very susceptible to the growing impact of global climate change and other anthropogenic influences. Consequently, there is an urgent need to understand how SO marine life will cope with expected future changes in the environment. Studies of Antarctic organisms have shown that individual species and higher taxa display different degrees of sensitivity to environmental shifts, making it difficult to predict overall community or ecosystem responses. This emphasizes the need for an improved understanding of the Antarctic benthic ecosystem response to global climate change using a multitaxon approach with consideration of different levels of biological... |

The Census of the Diversity of Abyssal Marine Life (CeDAMar), a division of the Census of Marine Life, has compiled the first comprehensive global database of biological samples taken in the abyssal plains of the world ocean. It is an essential resource for planning future exploration of the abyss, for synthesizing patterns of biogeography and biodiversity, and for environmentally safe exploitation of natural resources. The database is described in this article, and made available to investigators through the CeDAMar website. |

Many countries are very active in marine research and operate their own research fleets. In this decade, a number of research vessels have been renewed and equipped with the most modern navigation systems and tools. However, much of the research gear used for biological sampling, especially in the deep-sea, is outdated and dependent on wired operations. The deployment of gear can be very time consuming and, thus, expensive. The present paper reviews wire-dependent, as well as autonomous research gear for biological sampling at the deep seafloor. We describe the requirements that new gear could fulfil, including the improvement of spatial and temporal sampling resolution, increased autonomy, more efficient sample conservation methodologies for morphological... |

A new collection of Serolidae (Crustacea, Malacostraca) from the deep sea of the West-Atlantic part of Antarctica has been studied. Descriptions of the new species Frontoserolis abyssalis n. sp. and Serolis arntzi n. sp. are presented. F. abyssalis n. sp. is very similar to F. acuminata (Sheppard, 1957) and F. aestimabilis (Brandt, 1988), but can easily be distinguished from these by its vestigial eyes and a different ornamentation of head and pleotelson. S. arntzi n. sp. is most similar to S. rugosa, but can be discriminated from this species by the sculpture of the head, the pereonites and the pleotelson. |

Acanthaspidia namibia n. sp. was sampled off Namibia on the abyssal plain of the Angola Basin in 5390 m depth from board of the RV ‘Meteor’ in August 2000. Acanthaspidia neonotus (Menzies & George, 1972) is the most similar species, which has also been described from the deep sea, but from the Pacific Ocean in a comparative depth. The new species differs in bearing numerous long simple setae all over the body surface, and in the length of the maxillipedal epipod, which reaches the third palpal article, whereas that of A. neonotus reaches only the first. |

Storthyngura spinosissima n. sp. is described from material obtained from the Weddell Sea, south of Vestkapp and in the Drake Passage, at a depth of 417-1681 m. The new species is most similar to S. praegrandis George & Menzies, 1968, but differs in the following details: the dorsum of S. spinosissima n. sp. is covered by numerous small spine-like tubercles and short, hairlike setules, which are absent in S. praegrandis; the tubercles of the latter are less numerous; the interantennular space of S. spinosissima n. sp. is narrower than in S. praegrandis; the antennula of S. spinosissima n. sp. bears a less pronounced distomedial spine on the first peduncular article; and the uropodal endopods are slightly shorter and the exopods less wide in S.... |
