Riftia pachyptila, a species known as giant tube worms [1] Lamellibrachia, a genus; Serpulidae, a family; Sabellidae, the family containing feather duster worms; Phoronida, the phylum containing horseshoe worms; Microconchida, an order of extinct tubeworms; Kuphus polythalamia, a bivalve mollusk species whose common name is giant tube worm
These worms can reach a length of 3 m (9 ft 10 in), [3] and their tubular bodies have a diameter of 4 cm (1.6 in). Its common name "giant tube worm" is, however, also applied to the largest living species of shipworm, Kuphus polythalamius, which despite the name "worm", is a bivalve mollusc rather than an annelid.
Frenulata, "beard worms", is a clade of Siboglinidae, "tube worms". They are one of four lineages with numerous species. [1] [2] They may be the most basal clade in the family. [3] Despite being the first tube worms to be encountered and described, they remain the least studied group.
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 ...
The giant tube worm lives inside a long narrow tube made from a chitin, that is the hard material of its outer skeleton, and it attaches to the ocean floor. [3] It possesses a retractable plume that is extended when the worm is not disturbed. Its size can go up to 2 metres (6.6 ft) tall.
Serpula columbiana, variously called the calcareous tubeworm, plume worm, fan worm, limy tube worm and red tube worm, [2] is a species of segmented marine polychaete worm in the family Serpulidae. It is a cosmopolitan species that is found in most seas in the Northern Hemisphere including the Atlantic Ocean, the Pacific Ocean and the Indian Ocean.
Chaetopterus or the parchment worm or parchment tube worm is a genus of marine polychaete worm that lives in a tube it constructs in sediments or attaches to a rocky or coral reef substrate. [ 1 ] [ 2 ] [ 3 ] The common name arises from the parchment -like appearance of the tubes that house these worms. [ 3 ]
Unlike the tube worms Riftia pachyptila that live at hydrothermal vents, L. luymesi uses a posterior extension of its body called the root to take up hydrogen sulfide from the seep sediments. L. luymesi may also help fuel the generation of sulfide by excreting sulfate through their roots into the sediments below the aggregations. [2]
