The idea of a tooth worm is a theory of the cause of dental caries, periodontitis and toothaches. Once widespread, the belief is now obsolete, having been superseded by more scientific rationales. It was supposed that the disease was caused by small worms resident within the tooth, eating it away. [1]
Pompeii worms simultaneously keep their heads (including the gills) in much cooler water while their tails are exposed to hot water. Since their internal temperature has yet to be measured, a Pompeii worm may survive exposure to hot water by dissipating heat through its head to keep its internal temperature within the realm previously known to ...
Limnodrilus hoffmeisteri is conveyor-belt feeder that ingests particles in deep sediments and egests them on the sediment surface in the form of pseudofeces. [5] [6] The activities of this worm can alter sediment stratification, [6] [7] [8] increase the water content and porosity of sediment, [9] change the distribution of sediment particle size, [6] [10] alter the oxygen and nutrient dynamics ...
Paralvinella sulfincola, also known as the Sulfide worm, is a species of polychaete worm of the Alvinellidae family that thrives on undersea hot-water vents.It dwells within tubes in waters surrounding hydrothermal vents, in close proximity to super-heated fluids reaching over 300 °C (572 °F).
Vents can be characterized by temperature and chemical composition as diffuse vents which release clear relatively cool water usually below 30 °C, as white smokers which emit milky coloured water at warmer temperatures, about 200-330 °C, and as black smokers which emit water darkened by accumulated precipitates of sulfide at hot temperatures ...
Hammerhead worms are a part of the phylum Platyhelminthes, which includes all flatworms. This genealogical membership gives them the ability to become two different, genetically identical ...
The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion.
