Caldithrix is a genus of thermophilic and anaerobic bacteria, currently assigned to its own phylum.
Nautilia profundicola is a Gram-negative chemolithoautotrophic bacterium found around hydrothermal vents in the deep ocean. It was first discovered in 1999 on the East Pacific Rise at depth of 2,500 metres (8,200 ft), on the surface of the polychaete worm Alvinella pompejana. Nautilia profundicola lives symbiotically on the dorsal hairs of A. pompejana but they may also form biofilms and live independently on the walls of hydrothermal vents. The ability of N. profundicola to survive in an anaerobic environment rich in sulfur, H2 and CO2 of varying temperature makes it a useful organism to study, as these are the conditions that are theorized to have prevailed around the time of the earliest life on earth.
Exiguobacterium is a genus of bacilli and a member of the low GC phyla of Bacillota. Collins et al. first described the genus Exiguobacterium with the characterization of E. aurantiacum strain DSM6208T from an alkaline potato processing plant. It has been found in areas covering a wide range of temperatures (-12 °C—55 °C) including glaciers in Greenland and hot springs in Yellowstone, and has been isolated from ancient permafrost in Siberia. This ability to survive in varying temperature extremes makes them an important area of study. Some strains in addition to dynamic thermal adaption are also halotolerant, can grow within a wide range of pH values (5-11), tolerate high levels of UV radiation, and heavy metal stress.
Thermodesulfobacterium hydrogeniphilum is a species of Sulfate-reducing bacteria. It is thermophilic, chemolithoautotrophic, non-spore-forming, marine species, with type strain SL6T.
Caminibacter hydrogeniphilus is a species of thermophilic, hydrogen-oxidizing bacterium. It is anaerobic, rod-shaped, motile and has polar flagella. The type strain is AM1116T.
Desulfotomaculum geothermicum is a thermophilic, fatty acid-degrading, sulfate-reducing bacterium. It is capable of growing at temperatures of up to 80 °C (176 °F) and is commonly found in geothermal environments, such as hot springs and deep-sea hydrothermal vents. The species was first isolated from a hot spring in Beppu, Japan, in 1992 and was later characterized in detail.
Caminibacter profundus is a species of moderately thermophilic, microaerobic to anaerobic, chemolithoautotrophic bacterium. It is a Gram-negative, non-motile rod, with type strain CRT.
Deferribacter desulfuricans is a species of sulfur-, nitrate- and arsenate-reducing thermophile first isolated from a deep-sea hydrothermal vent. It is an anaerobic, heterotrophic thermophile with type strain SSM1T.

Paramaledivibacter caminithermalis has been isolated from a deep-sea hydrothermal vent from the Atlantic Ocean Ridge.
