Alvinella pompejana je druh hlbokomorského mnohoštetinavca.Je to extrémofil žijúci v hydrotermálnych prieduchoch v Pacifiku.Bol objavený na začiatku 80. rokov 20. storočia francúzskymi morskými biológmi.. Je dlhý asi 13 cm. This environment is considered as extreme and highly variable and the worm displays specific adaptations to withstand high temperature and hypoxia. tube-dwelling polychaete Alvinella pompejana showed reciprocal monophyly at mtCOI on each side of the Equator (9°50’N/7°25’S), suggesting potential, ongoing allopatric speciation. Secondary contact between previously isolated populations can occur when a member of the microbial mass on the dorsal surface of vent polychaete, Alvinella pompejana. ABSTRACT Alvinella pompejana is a polychaetous annelid inhabiting the surface of deep sea hydrothermal chimneys along the ridge of the east Alvinella pompejana is a polychaetous annelid inhabiting the surface of deep sea hydrothermal chimneys along the ridge of the east part of the Pacific ocean. The polychaete Alvinella pompejana lives exclusively on the walls of deep-sea hydrothermal vents along the East Pacific Rise. Key words: Annelids, molecular adaptations, ECM, development, reproduction. 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. This worm species can be found in thin tubes grouped together on the sides of th vents, close to the openings, where water from deep inside Earth pours out at temperatures of up to 350°C. The Pompeii worm (Alvinella pompejana) is an extremophile species of worm which lives in the hot water around hydrothermal vents in the Pacific Ocean. 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 … Continue reading below Our Featured Videos Alvinella pompejana, the “Pompeii worm” lives on active hydrothermal edifices at deep-sea vents of the East Pacific Rise.The physical and chemical patterns of its microhabitat were determined from temperature probe measurements, temperature time series, and on-board and shore-based chemical analyses based on discrete sampling (pH, H 2 S, CO 2, CH 4, S 2 O 2-3, Ca, Mg, Cu, Cd, Zn). Previous studies revealed the existence of a balanced polymorphism on the enzyme phosphoglucomutase … *Adaptation et Evolution en Milieux Extrêmes, SAE UMR 7138 CNRS IRD MNHN UPMC, 7 Quai Saint Bernard, 75005 Paris, France. The Pompeii worm (Alvinella pompejana), an enterprising creature that thrives in a real-life hell, where a living thing should have no business being. The main characteristic of this emblematic species is its habitat, which is very aggressive considering its temperature. 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. Analysis of the 1.7-Mbp genome of N. profundicola uncovered adaptations to the vent environment—some unique and some shared with other Epsilonproteobacterial genomes. However, the development of a barrier to gene flow is a long and complex process. The exceptional thermotolerance of this species (up to 80℃) has been the subject of much controversy. Žijú na ňom episymbiontické baktérie z triedy Epsilonproteobacteria, ktoré vytvárajú na jeho povrchu ochranný biofilm v tvare bielych chĺpkov.
