Terebellidae
The Terebellidae is a marine family of polychaete worms, of which the type taxon is '' Terebella'', described by Carl Linnaeus in his 1767 12th edition of ''Systema Naturae''. Characteristics Most terebellids live in burrows or crevices and are often of large size, ranging up to 150 millimetres in length and 15 millimetres in width. The numerous, very long tentacles which radiate from near the mouth are used for finding and collecting food particles from the sediment surface. The tentacles are not retractable as is the case in the ampharetids. They have plump anterior bodies and numerous segments in their long, tapered posterior bodies, whereas ampharetids are more compact. They have branched gills laterally on up to three anterior chaetigers but in the subfamily Thelepodinae the gills are numerous simple filaments. The mid-body chaetigers are in double rows in the subfamily Terebellinae. In the subfamily Polycirrinae, the gills are absent and the prostomium is expanded as ...

Biremis
''Biremis blandi'' is a species of marine polychaete worm and the only species in the genus ''Biremis''. It was first described by Polloni, Rowe, and Teal in 1973. The species was discovered in 1971 during a dive by the research submersible DSV ''Alvin'' at in the Tongue of the Ocean in the Bahamas. It is named for ''Alvin'' pilot Edward L. Bland, Jr., who first observed it. ''Biremis blandi'' is described as a terebellid worm with an enlarged tentacular lobe with numerous long tentacles, prominent longitudinal muscular ventral ridges, thoracic segments lacking chaetae, and abdominal segments with pinnules bearing uncini. The worm lacks eyes and gill A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are ...s. It has been observed swimming and resting on the ocean floor. References ...

Polychaeta
Polychaeta () is a paraphyletic class of generally marine annelid worms, 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 sandworm or 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'' at the bottom of the Challenger Deep, the deepest known spot in the Earth's oceans. Only 168 species (less than 2% of all polychaetes) are known fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
