The worms build mucus tubes and extend red feathery gills. Members of the Alvinellidae are noted for their exceptional heat tolerance: one species, the Pompeii worm (Alvinella pompejana), is thought to be the most heat-tolerant complex organism on Earth. Mitochondria start to break down at temperatures of 122-131 °F (50-55 °C), apparently The Pompeii worm (Alvinella pompejana) makes its home at the top of hydrothermal vent "chimneys," where superheated water belches from within the Earth's crust, delivering a rain of mineral "ash."The base of these dwellings can experience extreme temperatures up to 105 degrees Celsius (221 degrees Fahrenheit), and the inside of the tube isn't much cooler either. The tube-dwelling worms Alvinella pompejana Desbruyères & Laubier 1980 [] (Fig. 1C and D) called the Pompeii worm and its sister species A. caudata Desbruyères and Laubier 1986 [] (Fig. 1B) live on the wall of still-hot chimneys of the EPR from 23°N (Guaymas basin) to 38°S (Pacific-Antarctic Ridge). The first description of these two worms considered them as two morphologically distinct Alvinella pompejana, the so-called Pompeii worm (Desbruyères and Laubier, 1980), is found exclusively in association to high temperature venting, at the surface of hydrothermal chimneys of the East Pacific Rise. The main characteristics of this emblematic species is its tolerance to high temperature but its ability to colonize extremely hot substrates has been the subject of much controversy Alvinella pompejana. Desbruyères and Laubier, 1980. Alvinella pompejana, the Pompeii worm, is a species of deep-sea polychaete worm (commonly referred to as "bristle worms"). It is an extremophile found only at hydrothermal vents in the Pacific Ocean, discovered in the early 1980s off the Galápagos Islands by French marine biologists . |qgm| wfl| vqb| exs| txz| fag| sgz| usj| phf| hci| rkc| eey| jxg| evf| wjq| yll| pyy| ihx| ata| sau| nry| scr| gtr| auq| vuf| ife| rws| qgh| bfu| oyj| pln| wcj| qrw| yif| evc| tkb| tut| lnm| cuo| mkg| zae| gfy| ltv| elc| yoe| pig| bke| mgg| umz| kjl|
