This study deals with the organization of the coelom in the all the parts of the body of the vestimentiferan Oasisia alvinae. The localization of the dissepiment between the vestimental and trunk regions in males and females differs. The histological structure and anatomy of the trophosome and the vascular, excretory, and reproductive systems is described. Three cell types are distinguishable in each trophosome lobe. Up to four bacteriocytes could be found in a row from the central blood vessel… 
The anatomy of the blood vascular system of the giant vestimentiferan tubeworm Riftia pachyptila (Siboglinidae, Annelida)
TLDR
The 3D reconstruction has revealed that there are two vascular systems of the tentacular crown of R. pachyptila, and it appears that the presence of these vessels is the preserved ancestral state of Vestimentifera.

TLDR
Transmission electron microscopy and fluorescence microscopy allowed detection of sperm associated with ovarian tissue of the female ovisac of four different Osedax species, providing the first evidence for the site of internal fertilization in OsedAX.

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.

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.
Ultrastructural reinvestigation of the trophosome in adults of Riftia pachyptila (Annelida, Siboglinidae)
TLDR
A mesodermal rather than endodermal origin is hypothesized for the trophosome of adults of Riftia pachyptila and its constitute bacteriocytes, which act as stem cells for a proliferating tissue produced in the center and ultimately degraded at the periphery of each lobule.
Comparative anatomy of excretory organs in vestimentiferan tube worms (Pogonophora, Obturata)
TLDR
The vestimentiferan excretory system shows some similarities with the design in Athecanephria and a general resemblance to theDesign in sabellid polychaetes, even though in the latter metanephridia are clearly present.
Sperm masses and sperm transfer in a vestimentiferan, Ridgeia piscesae Jones, 1985 (Pogonophora: Obturata)
Discrete sperm masses, of irregular outline, 2–5 mm in their maximum dimension, were found on males and females of Ridgeia piscesae Jones, 1985 (Pogonophora: Obturata), hydrothermal vent tube worms
Light and scanning electron microscopic studies of spermatogenesis in the vestimentiferan tube worm Riftia pachyptila (Pogonophora: Obturata)
TLDR
The process of spermatogenesis was studied in the obturate pogonophoran Riftia pachyptila from hydrothermal vents on the Galapagos Rift, where earlier stages appear to be at variance with those of the perviates.
Sperm Storage, Internal Fertilization, and Embryonic Dispersal in Vent and Seep Tubeworms (Polychaeta: Siboglinidae: Vestimentifera)
TLDR
It is shown experimentally that most eggs are inseminated internally, that fertilization rate is typically lower than 100%, that meiosis is completed after eggs are released from the female, and that the dispersal phase includes the entire embryonic period.
