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.
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 ...
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.
Each worm has two crowns, which come in a variety of different colors, and are spiraled in the shape of a Christmas tree. 5 cm (2.0 in) Cluster duster [1] Bispira brunnea: Yes: Moderate: This species grows in groups of up to 100 individual tube worms, living together in a single clump. The clusters of tubes adhere to a rocky substrate at a ...
The tubes may weave together, and as new worms settle on the outer surface, the reef becomes a solid mass. [10] Reefs of worms can be over 7 m (23 ft) long. [ 2 ] When the invasion of Lake of Tunis in Tunisia was at its most severe, the total reef mass of the lagoon was thought to contain about 540,000 tons of carbonate. [ 11 ]
There was disagreement among zoologists in the 18th century as to whether the creature which made one of these was a polychaete tube-worm or came from a mollusc. Linnaeus described the species in 1758. He considered that it was a serpulid worm and named it Serpula arenaria, a name which in 1767 he changed to Serpula polythalamia.
The worms are unique among the polychaete worms in the highly derived parapodia of the mid-segments of its body that are used in its specialized filter feeding regime. [3] The worm's parapodia are modified into the shape of fans and used to create suction and pump water through the worm's parchment living tube. [3]
