Polychaete - Wikipedia
The most generalised polychaetes are those that crawl along the bottom, but others have adapted to many different ecological niches, including burrowing, swimming, pelagic life, tube-dwelling or boring, commensalism, and parasitism, requiring various modifications to their body structures.
A Cambrian crown annelid reconciles phylogenomics and the
2020年6月11日 · Here we describe a new fossil polychaete (bristle worm) from the early Cambrian Canglangpu formation 7 that we name Dannychaeta tucolus, which is preserved within delicate, dwelling tubes...
Polychaetes as Habitat Former: Structure and Function
2021年2月6日 · The sedentary polychaetes belonging to the family Sabellariidae are sessile, tube-dwelling species which build tubes from sand and shell fragments cemented together with mucous. Such worms build reefs on sand flats where elements of hard substratum are exposed and used for the settlement of pioneering larvae.
Textures and traction: how tube-dwelling polychaetes get a leg up
2015年3月3日 · To examine the potential physical interaction between worms and the tubes they live in, scanning electron microscopy was used to reveal and quantify the morphology of worm bodies and the tubes they produce for species representing 13 families of tube-dwelling polychaetes. In the tubes of most species there were macroscopic or nearly macroscopic ...
Endosymbiont genomes yield clues of tubeworm success
2018年7月18日 · We hypothesize that over evolutionary time siboglinids have been able to utilize different bacterial lineages allowing greater metabolic flexibility of carbon fixation (e.g., rTCA) enabling...
Eocene tube-dwelling annelids (Polychaeta: Sedentaria) from the …
2022年3月23日 · Tube-dwelling polychaetes, or tubeworms that construct calcareous tubes, represent an important part of marine benthic communities that encrust hard substrates (ten Hove and van den Hurk 1993; Taylor and Wilson 2003; Vinn and Wilson 2010; Schlögl et al. 2008; Zatoń et al. 2011).
Textures and traction: How tube-dwelling polychaetes get a leg …
2015年3月1日 · By controlling the traction between its body and the tube wall, a tube-dwelling polychaete can move efficiently from one end of its tube to the other, brace its body during normal functions...
New Perspectives on the Ecology and Evolution of Siboglinid
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.
Tube worm | annelid | Britannica
Tube worm, any of a number of tube-dwelling marine worms belonging to the annelid class Polychaeta (see polychaete; feather-duster worm; tentacle worm). Other tube-dwelling worms include the horseshoe worm (phylum Phoronida) and the beardworm (phylum.
Devonian agglutinated polychaete tubes: all in all it's just another ...
2021年7月28日 · Here we present a novel type of agglutinated tube from the austral and endemic palaeobiota of the Malvinokaffric realm (Devonian, Brazil). This fossil is characterized by an agglutinated tube made of silt-sized particles forming an unusual flanged morphology that is not known from the fossil record.
