Allometric growth in post-embryonic development was studied in the hydrothermal vestimentiferan Oasisia alvinae Jones, 1985. In the process of growth, the length of the trunk region increases relative to the total body length from 51 to 83.4%, whereas the relative sizes of the obturacular region, vestimental region, and the opisthosoma decrease. This is connected with a strong development of the trophosome and gonads in the trunk region. It is suggested that the predominant growth of the trunk…

Geochemistry drives the allometric growth of the hydrothermal vent tubeworm Riftia pachyptila (Annelida: Siboglinidae)
TLDR
Two morphotypes are described, ‘fat’ and ‘slim’, respectively, from the basalt sulphide-rich vents at 9 °N and 21 °N at the East Pacific Rise, and the highly sedimented, sulphides-poor vents at 27 °N in the Guaymas Basin, which are suggested to keep the sulphide uptake near to the optimum values for the symbionts.

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.

TLDR
This result, indicating the derived loss of segmentation in echiurans, has profound implications for the understanding of the evolution of metazoan body plans and challenges the traditional view of the phylum-level diversity and evolutionary relationships of protostome worms.
Phylogeny of Vestimentifera (Siboglinidae, Annelida) inferred from morphology
TLDR
The biogeography is consistent with the recent divergence of Vestimentifera as inferred from molecular data and Hypothesized homologies of the vestimentiferan obturaculum and vestimentum to structures in related taxa need further investigation.
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.
The articulation of annelids
TLDR
The Annelida should not be used unless relationships within the Articulata are resolved to show it is a monophyletic taxon, and the Pogonophora should revert to the original family name Lamellisabellidae Uschakov, 1933.
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.
Molecular phylogeny of siboglinid annelids (a.k.a. pogonophorans): a review
TLDR
The literature to date on siboglinid molecular phylogeny is reviewed and a summary of the clade’s evolution is summarized.

Biometry of the branchial plume in the hydrothermal vent tubeworm Riftia pachyptila (Vestimentifera; Annelida)
TLDR
The branchial plume of the hydrothermal vent tubeworm Riftia pachyptila is the main organ by which this mouth- and gut-less tubew Worm directly exchanges metabolites with its environment, and the total branchial surface area per unit wet mass is estimated from planimetric measurements.
On the Vestimentifera, new phylum: six new species, and other taxa, from hydrothermal vents and elsewhere
TLDR
Le sousphylum obturata (phylum des Pogonophora) au rang d'un nouveau phylum les Vestimentifera est restaure dans son statut original comme phylum Pogonphora.
