Functional morphology and ecology of the Arctic pogonophore Nereilinum murmanicum Ivanov, 1961 (Siboglinidae, Annelida)
This article deals with the external and internal morphology in the adult stages of Nereilinum murmanicum Ivanov, 1961, a widespread species of Siboglinidae in the Barents Sea. Since Siboglinidae is currently a taxon within the phylum Annelida, we revised the commonly held view of the body segmentat...
