Siboglinidae - Wikipedia
Siboglinidae is a family of polychaete annelid worms whose members made up the former phyla Pogonophora and Vestimentifera (the giant tube worms). [1][2] The family is composed of around 100 species of vermiform creatures which live in thin tubes buried in sediment (Pogonophora) or in tubes attached to hard substratum (Vestimentifera) at ocean d...

Siboglinidae - an overview | ScienceDirect Topics
Siboglinidae is a specific group of marine annelids with adults that characterized by a lack of a digestive tract, so they get nutrients from bacterial endosymbionts cultivated in a special parenchymal organ called the trophosome, or root tissue in the case of Osedax.

2009年11月10日 · The initial description of Osedax included a phylogenetic analysis that placed the new genus in the polychaete annelid family Siboglinidae, which also includes the now obsolete tubeworm phyla Vestimentifera and Pogonophora [9, 10]. As adults, all siboglinids lack a functional digestive system and rely entirely on endosymbiotic bacteria for ...

2023年5月17日 · a Siboglinidae is a diverse clade of annelid worms that evolved chemosynthetic symbioses (left side). There are four main lineages within Siboglinidae, namely Frenulata, Osedax , Sclerolinum...
Progress in systematics: from Siboglinidae to Pogonophora …
2009年2月1日 · We review the taxonomic history of pogonophores (frenulates and vestimentiferans), from the species in first described 1914 to the recently described bone-eating worm Osedax. Previous systematists have referred both groups to the rank of phylum, and the animals have been treated as deuterostomes with a dorsal nerve cord.

2011年2月14日 · Siboglinids are tube-dwelling annelids that are important members of deep-sea chemosynthetic communities, which include hydrothermal vents, cold seeps, whale falls and reduced sediments. As adults, they lack a functional digestive system and rely on microbial endosymbionts for their energetic needs.
Pogonophora (Annelida): form and function | Hydrobiologia
Pogonophora, also known as Siboglinidae, are tube-dwelling marine annelids. They rely on endosymbiotic chemoautotrophic bacteria for nutrition and their anatomy and physiology are adapted to their need to obtain both oxygen and reduced sulphur compounds.
