Five species of three genera of Dirivultidae Humes and Dojiri, 1980 were found at deep-sea hydrothermal vent fields on the Mid-Atlantic Ridge, at the Logachev-1 field at 14ºN and at two new sites (Turtle Pits and Red Lion) explored at 5ºS. The copepods were collected with a Remotely Operated Vehicle (ROV Quest 4000) and Video Controlled Grab, operated from the R/V Meteor during two cruises (M60/3 and M64/1) conducted in 2004 and 2005 at depths 2992–3048 m. The male of Stygiopontius lomonosovi n. sp. from the Logachev field shares a medioventrally prolonged syncoxa of the maxilliped with S. mirus Humes, 1996 and S. latulus Humes, 1996 from the Snake Pit at 23ºN of the Mid-Atlantic Ridge, but differs from them in having two, instead of three, outer spines on the distal exopodal segment of leg 4. Aphotopontius atlanteus Humes, 1996 previously known from the Lucky Strike and the Menez Gwen sites at 37°N and Rimipontius mediospinifer Humes, 1996 known from three sites (Logachev, Snake Pit, and Broken Spur at 29°N) are recorded from the Logachev field. Stygiopontius pectinatus Humes, 1987 previously recorded from the Mid-Atlantic Ridge hydrothermal vent fields TAG (26°N), Snake Pit, Broken Spur (29°N), and from the Mariana Back-Arc Basin of the Pacific Ocean and Stygiopontius cladarus Humes, 1996 previously known only from Snake Pit and Broken Spur, were found associated with alvinocaridid shrimps (Rimicaris sp.) from the hydrothermal vent field at 5ºS. The discovery of dirivultids at 5ºS represents the first record of copepods from a deep-sea hydrothermal vent southward of the Logachev field in the Atlantic Ocean.

The diversity of bathyal and abyssal marine organisms is still poorly known and this is especially true for tubicolous polychaetes of the family Serpulidae, the common inhabitants of subtidal and shelf locations. We report herein new records of poorly known deep-sea (mostly below 2000 m) serpulids collected in the Pacific Ocean by early Soviet Oceanographic expeditions onboard R/V “Vityaz”. The following species were found: Bathyditrupa hovei, Bathyvermilia challengeri, B eliasoni, B. zibrowiusi, Filogranula stellata, Hyalopomatus jirkovi, and H. sikorski at the depths of 1600–6330 m. Many samples collected by R/V “Vityaz” and other Russian research vessels are still unstudied and apparently many bathyal and abyssal serpulid species new to science remain undescribed. The diversity of abyssal marine organisms remains poorly known not only because of the obvious logistical difficulties in collecting at abyssal localities, but also in part due to the lack of taxonomic effort directed towards existing research collections.

A new genus, Portaratrum n. gen. and two new species, one from the Atlantic Ocean and one from the Pacific Ocean are described. The new genus is characterized by a downwardly directed pleonal spur, cheliped basis fused to the cephalothorax, biramous uropods, pars molaris blunt with several terminal spinules. At present the genus is assigned to the family Colletteidae. Both species were collected from depths exceeding 4000 m.

No reports have been published about symbiotic penicillate millipeds living in arboreal ant nests, though Donisthorpe (1927) reported those in edaphic ant nests. Therefore, we tried to determine the species and numbers of symbiotic penicillate millipeds in arboreal ant nests.An investigation of the symbiotic penicillate millipeds was conducted in both the maritime forest (Daphniphyllum teijsmannii Zoll., Pinus thunbergii Parl.) and the mountain forest (Machilus thunbergii Sieb. et Zucc., Castanopsis cuspidata Schottky var. sieboldii Nakai) on Miyakejima Island (about N 34°05′, E 139°30′) in the Pacific Ocean, 28 March 1980. As a result, we found symbiotic penicillate millipeds of the family Polyxenidae only in the maritime forest.

Ocean Ridge

Deep-sea hydrothermal vents and methane seeps are inhabited by members of the same higher taxa but share few species, thus scientists have long sought habitats or regions of intermediate character that would facilitate connectivity among these habitats. Here, a network analysis of 79 vent, seep, and whale-fall communities with 121 genus-level taxa identified sedimented vents as a main intermediate link between the two types of ecosystems. Sedimented vents share hot, metal-rich fluids with mid-ocean ridge-type vents and soft sediment with seeps. Such sites are common along the active continental margins of the Pacific Ocean, facilitating connectivity among vent/seep faunas in this region. By contrast, sedimented vents are rare in the Atlantic Ocean, offering an explanation for the greater distinction between its vent and seep faunas compared with those of the Pacific Ocean. The distribution of subduction zones and associated back-arc basins, where sedimented vents are common, likely plays a major role in the evolutionary and biogeographic connectivity of vent and seep faunas. The hypothesis that decaying whale carcasses are dispersal stepping stones linking these environments is not supported.
