Pogonophora or siboglinid tubeworms (Annelida, Siboglinidae) have been found in the East Siberian Sea for the first time. On the basis of the results of molecular phylogenetic analysis, the found specimens are presumably assigned to the genus Oligobrachia. The stations where the siboglinid tubeworms have been found are located in the area of methane seeps. This confirms the previously stated hypothesis about relationship of siboglinid tubeworm distribution with the areas of underwater methane…

New Perspectives on the Ecology and Evolution of Siboglinid Tubeworms
TLDR
The role of ecological conditions in the evolution of siboglinids is discussed and possible scenarios of the evolutionary origin of the symbiotic relationships between sibogslinids and their endosymbiotic bacteria are presented.
A revision of the Oligobrachiidae (Annelida: Pogonophora), with notes on the morphology and distribution of Oligobrachia haakonmosbiensis Smirnov
TLDR
The species redescribed here is shown to have a wider distribution than previously known and the presence of glandular patches confirms the closest morphological affinity between O. haakonmosbiensis and O. webbi, the two North Atlantic pogonophorans of the genus Oligobrachia.

Endosymbioses between bacteria and deep-sea siboglinid tubeworms from an Arctic Cold Seep (Haakon Mosby Mud Volcano, Barents Sea).
TLDR
The molecular data suggest that both HMMV tubeworm species harbour chemoautotrophic sulfur-oxidizing symbionts and that the dominant bacterial phylotypes originated from endosymbionts residing inside the host trophosome.
Current status of annelid phylogeny
TLDR
The new annelids phylogeny highlights the variability and lability of annelid body plans, and many instances of simplifications of body plan as adaptations to new life styles can be found.
Bacterial Endosymbioses of Gutless Tube-Dwelling Worms in Nonhydrothermal Vent Habitats
TLDR
Observations demonstrate that pogonophoran and vestimentiferan worms have higher plasticity in bacterial symbioses than previously suspected.
Methane seeps on the outer shelf of the Laptev Sea: characteristic features, structural control, and benthic fauna
Two areas with cold methane seeps on the outer shelf of the Laptev Sea were studied by two interdisciplinary expeditions onboard the RV Akademik Mstislav Keldysh in August–September of 2017 and 2018.…
Frenulate siboglinids at high Arctic methane seeps and insight into high latitude frenulate distribution
TLDR
The results point toward a single speciation event within the Oligobrachia clade, and it is suggested that this occurred in the late Neogene, when topographical changes occurred and exchanges between Arctic and North Atlantic water masses and subsequent thermohaline circulation intensified.
