Sabellidae
Sabellidae, or feather duster worms, are a family of marine polychaete tube worms characterized by protruding feathery branchiae. Sabellids build tubes out of a tough, parchment-like exudate, strengthened with sand and bits of shell. Unlike the other sabellids, the genus '' Glomerula'' secretes a tube of calcium carbonate instead. Sabellidae can be found in subtidal habitats around the world. Their oldest fossils are known from the Early Jurassic. Characteristics Feather-duster worms have a crown of feeding appendages or radioles in two fan-shaped clusters projecting from their tubes when under water. Each radiole has paired side branches making a two-edged comb for filter feeding. Most species have a narrow collar below the head. The body segments are smooth and lack parapodia. The usually eight thoracic segments bear capillaries dorsally and hooked chaetae (bristles) ventrally. The abdominal segments are similar, but with the position of the capillaries and chaetae reversed. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radiole
A radiole is a heavily ciliated feather-like tentacle found in highly organized clusters on the crowns of Canalipalpata. Canalipalpata is an order of sessile marine polychaete worms consisting of 31 families (including the Sabellidae, Serpulidae, Terebellidae, and Alvinellidae, a family of deep-sea worms associated with hydrothermal vents). These benthic annelid tube worms employ radioles primarily for alimentation. While their primary role is to function as an organ for filter feeding, radioles also serve as respiratory organs. Because of their role in gas exchange, radioles are often referred to as "gills". Anatomical location Canalipalpata have a head located at the anterior end of the body. The head is formed by the fusion of a funnel-shaped, symmetrical peristomium with the prostomium.Department of Biology, Walla Walla UniversitySerpula vermicularis, Rosario Beach Marine Laboratory. Accessed 3 May 2010. The prostomium bears a specialized mouth appendage which is referred to as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glomerula
''Glomerula'' is a genus of polychaete, polychaete worm in the family Sabellidae. It differs from all other Sabellidae in having a calcareous tube and spinose setae. Only one living species, ''G. piloseta'', is known from Lizard Island National Park, Lizard Island, Great Barrier Reef, Australia. The oldest fossils of ''Glomerula'' are known from the Early Jurassic and their tube microstructure has remained unchanged since then.

Polychaete
Polychaeta () is a paraphyletic class (biology), class of generally marine invertebrate, marine annelid worms, common name, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the Alitta virens, sandworm or Alitta succinea, clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe Nereus (underwater vehicle), ''Nereus'' at the bottom of the Challenger Deep, the deepes ...

Eudistylia
''Eudistylia'' is a genus of marine polychaete worms. The type species is ''Eudistylia gigantea'', now accepted as ''Eudistylia vancouveri''. This worm lives in a parchment-like tube with a single opening from which a crown of tentacles projects when the worm is submerged. It is a sessile filter feeder. the Eudistylia Vancouveri is unique because it has an opiculum which makes it possible to fully retract into the tube when predators are sensed. Characteristics The head is formed from the prostomium and peristomium, which are fused. It bears two bundles of radioles or feeding tentacles which together form the funnel-shaped multicolored branchial crown divided into two groups on the dorsal and ventral side of the head. Each radiole is pinnately divided and covered in cilia. It has a central stiffening rod of connective tissue, a number of eyespots and a feeding groove. There are a pair of small palps beside the radioles and a large funnel-shaped mouth. There are about eight thoraci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
