Taxonomy, geographical and bathymetric distribution of vestimentiferan tubeworms (Annelida, Siboglinidae)
TLDR
The hypothesis on the Pacific origin on vestimentiferan tubeworms has been discussed, and the eurybathic Lamellibrachiinae and Escarpiinae penetrated into the Atlantic Ocean through shallow-water basins of the Tethys Ocean and channels in the place of Mesoamerica, while the deep-sea Tevniinae were not able to do that.
The morphology and anatomy of the vestimentiferan worm Oasisia alvinae Jones, 1985 (Annelida: Siboglinidae). II. Integument, nervous system and musculature
TLDR
The histological structure of the epidermis, nervous system, and musculature of the vestimentiferan worm Oasisia alvinae is examined and an attempt is made to homologize parts of the Vestimentaliferan brain with the polychaete brain.
A new genus of frenulates (Annelida: Siboglinidae) from shallow waters of the Yenisey River estuary, Kara Sea
TLDR
A new genus and a new species of frenulates Crispabrachia yenisey are described and the tube structure with prominent frills and the worm’s numerous tentacles, metameric papillae with cuticular plaques and segmental furrow on the forepart indicate that the new genus belongs to the polybrachiid group.
Postembryonic Development of the Hydrothermal Vestimentiferan Oasisia alvinae Jones, 1985 (Annelida, Siboglinidae)
TLDR
It is suggested that the predominant growth of the trunk region during ontogeny is a common pattern for all vestimentiferans.
Changes in Body Proportions during Growth of the Hydrothermal Vestimentiferan Oasisia alvinae Jones 1985 (Annelida, Siboglinidae)
During the growth of hydrothermal vestimentiferan Oasisia alvinae the trunk part of body was found to be elongated (from 51 to 83.4% of the overall body length), while the relative dimensions of all
First Discovery of Pogonophora (Annelida, Siboglinidae) in the Kara Sea Coincide with the Area of High Methane Concentration
TLDR
The first finding of a frenulate pogonophoran (Annelida, Siboglinidae) in the southern part of the Kara Sea is reported, in the region of the highest methane concentrations, resulting from the degradation of permafrost under the influence of river flow.
The morphology and anatomy of the vestimentiferan worm Oasisia alvinae Jones, 1985 (Annelida: Siboglinidae). I. External morphology, obturaculae and tentacles
TLDR
The tube structure, external morphology, and histological organization of the obturacula and tentacles of the small hydrothermal-vent vestimentiferan worm Oasisia alvinae are described, suggesting a step-like growth of the worm.
The morphology and anatomy of the vestimentiferan worm Oasisia alvinae Jones, 1985 (Annelida: Siboglinidae). III. Coelomic cavity, trophosome and blood, excretory and reproductive systems
TLDR
The histological structure and anatomy of the trophosome and the vascular, excretory, and reproductive systems is described, and the reproductive system is symmetrical in males and dissymmetrical in females.
The First Discovery of Pogonophora (Annelida, Siboglinidae) in the East Siberian Sea Coincides with the Areas of Methane Seeps.
TLDR
The found specimens are presumably assigned to the genus Oligobrachia and the previously stated hypothesis about relationship of siboglinid tubeworm distribution with the areas of underwater methane seeps is confirmed.
