“…, 1994). Siboglinum poseidoni reaches a maximum length of 19 cm (Flügel and Callsencencic, 1992), and shows no mechanism for the active uptake of methane, and therefore appears to be restricted to areas with high methane concentrations, close to the sediment surface. Activity of the key enzyme of the ribulose monophosphate pathway of C 1 assimilation, hexulose 6‐phosphate synthase, was shown in S. poseidoni (Schmaljohann et al.…”

“…The tubeworms are only present in steeply sloping areas where mudslides expose the deeper sediment layers, bringing methane-saturated sediment to within 20 cm of the sea floor (Dando et al, 1994). Siboglinum poseidoni reaches a maximum length of 19 cm (Flügel and Callsencencic, 1992), and shows no mechanism for the active uptake of methane, and therefore appears to be restricted to areas with high methane concentrations, close to the sediment surface. Activity of the key enzyme of the ribulose monophosphate pathway of C 1 assimilation, hexulose 6-phosphate synthase, was shown in S. poseidoni (Schmaljohann et al, 1990), indicating that its symbionts may be related to type I methanotrophs.…”

Symbioses between marine animals and aerobic methane-oxidizing bacteria are found at hydrothermal vents and cold seeps in the deep sea where reduced, methane-rich fluids mix with the surrounding oxidized seawater. These habitats are 'oases' in the otherwise nutrient-poor deep sea, where entire ecosystems are fueled by microbial chemosynthesis. By associating with bacteria that gain energy from the oxidation of CH4 with O2 , the animal host is indirectly able to gain nutrition from methane, an energy source that is otherwise only available to methanotrophic microorganisms. The host, in turn, provides its symbionts with continuous access to both electron acceptors and donors that are only available at a narrow oxic - anoxic interface for free-living methanotrophs. Symbiotic methane oxidizers have resisted all attempts at cultivation, so that all evidence for these symbiotic associations comes from ultrastructural, enzymatic, physiological, stable isotope and molecular biological studies of the symbiotic host tissues. In this review, we present an overview of the habitats and invertebrate hosts in which symbiotic methane oxidizers have been found, and the methods used to investigate these symbioses, focusing on the symbioses of bathymodiolin mussels that have received the most attention among methanotrophic associations.

“…Thus, cold seep vestimentiferans-representatives of the genera Lamellibrachia, Seepiophila and Escarpiareach high numbers around hydrocarbon seeps in the Gulf of Mexico and on the slope off Louisiana [55][56][57][58][59][60][61][62][63]. This pattern is also valid for siboglinids of the subfamilies Frenulata and Monilifera [16,31,48,[64][65][66][67][68][69][70][71][72][73][74][75][76][77].…”

Frenulate siboglinids are a characteristic component of communities living in various reducing environments, including sites with hydrocarbon seeps. High concentrations of hydrocarbons in the sediments of the Arctic basin seas, including the Barents Sea, suggest the presence of a rich siboglinid fauna there. This reflects the fact that microbiological oxidation of methane occurs under reducing conditions, generating high concentrations of hydrogen sulfide in the sediment. This hydrogen sulfide acts as an energy source for the sulfide-oxidizing symbionts of siboglinids. Here we report on the findings of the frenulate siboglinid species Nereilinum murmanicum made between 1993 and 2020 in the Barents Sea. These data significantly expand the range of this species and yield new information on its habitat distribution. The depth range of N. murmanicum was 75–375 m. The species was most abundant from 200 to 350 m and was associated with temperatures below 3 °C and salinities from 34.42 to 35.07. Most of the findings (43 locations or 74%) fall on areas highly promising for oil and gas production. Twenty-eight locations (48%) are associated with areas of known oil deposits, 22 locations (37%) with explored areas of gas hydrate deposits. N. murmanicum was also found near the largest gas fields in the Barents Sea, namely Shtokman, Ludlovskoye and Ledovoye.

“…However, another dominant faunal community member at HMMV is a siboglinid frenulate species of Oligobrachia which at the time was described as a novel species new to science and named after the site (Oligobrachia haakonmosbiensis) [34]. Since frenulates can be seep specific (e.g., Siboglinum poseidoni) and the seep habitat contains higher levels of sulfide and methane than the habitats of non-seep specialist frenulates [35][36][37][38], it was possible that O. haakonmosbiensis was specialized for the seep environment of HMMV. However, the species description of O. haakonmosbiensis was subsequently questioned because the fjord frenulate Oligobrachia webbi [39] was morphologically very similar.…”
