1A marine bristle worm, especially a fan worm, which lives in a tube made from sand particles or in a calcareous tube that it secretes.
- ‘But he cherishes the occasional feather duster, a small tube worm that opens from live rock or other housing into a red and white umbrella of feathery tentacles, sifting the water for planktonic food.’
- ‘The baleen acts as a filter or strainer retaining only the food, which the whale maneuvers with its tongue so the gammarid amphipods, tube worms, mollusks, and other bottom invertebrates can be swallowed.’
- ‘Other types of deep-sea hot spots include hydrothermal vent communities, where specially adapted crabs, clams, and odd-looking tube worms gather around mineral-rich hot springs.’
- ‘Aside from its temporary and permanently resident fish, the underside is decorated with sponges, hydroids, tunicates, tube worms, cup corals and anemones.’
- ‘During this first dive, the team did discover a garden possibly less than one year old with tiny tube worms, mussels and clams all living together.’
- 1.1A pogonophoran or vestimentiferan worm.
- ‘This food web is taken to the extreme in the Pogonophora tube worms that are found at some vents.’
- ‘The presence of vestimentiferan tube worm fossils in the Figueroa deposit is at odds with the supposed time of origin of the modern vestimentiferans, based on molecular data.’
- ‘ONE OF the most conspicuous groups of animals living in deep-sea chemosynthetic communities at hydrothermal vents are large vestimentiferan tube worms.’
- ‘The Figueroa assemblage shares gastropods and vestimentiferan tube worms with both modern and other ancient vent communities, but is unique in containing rhynchonellide brachiopods.’
- ‘They are members of the phylum Annelida, the group that includes segmented worms such as leeches, tube worms, and the familiar earthworm.’
