Riftia pachyptila, commonly known as the giant tube worm and less commonly known as the giant beardworm, is a marine invertebrate in the phylum Annelida [1] (formerly grouped in phylum Pogonophora and Vestimentifera) related to tube worms commonly found in the intertidal and pelagic zones.

Lamellibrachia is a genus of tube worms related to the giant tube worm, Riftia pachyptila.They live at deep-sea cold seeps where hydrocarbons (oil and methane) leak out of the seafloor, and are entirely reliant on internal, sulfide-oxidizing bacterial symbionts for their nutrition.
Little is known about microbes that use hydrogen as a source of energy, however, studies have shown that they are aerobic, and also symbiotic with Riftia (see below). [11] [27] These bacteria are important in the primary production of organic carbon because the geothermally-produced H 2 is taken up for this process. [11]
Deep in the Gulf of California, scientists have discovered a fantastical expanse of hydrothermal vents, full of crystallized gases, glimmering pools of piping-hot fluids and rainbow-hued life ...
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 depths ranging from 100 to 10,000 m (300 to ...
A trophosome is a highly vascularised organ found in some animals that houses symbiotic bacteria that provide food for their host. Trophosomes are contained by the coelom of tube worms (family Siboglinidae, e.g. the giant tube worm Riftia pachyptila) [1] and in the body of symbiotic flatworms of the genus Paracatenula.
