  HESIOCAECA METHANICOLA, A CLATHRATE DWELLING POLYCHAETE   (Site not responding. Last check: 2007-10-26)
Hesiocaeca methanicola lives on methane clathrates in the deep-sea.
However, several lines of evidence indicate abundant bacteria are associated with the surface of the hydrate, and we hypothesize that these bacteria are the dominant food source for the clathrate polychaetes.
The anaerobic tolerance of H. methanicola is at the upper end of that reported for other polychaetes, and they oxy-regulate down to about 10% of air saturation.

 NOAA Ocean Explorer: Deep East
Micrograph of iceworm, Hesiocaeca methanicola, discovered living in a hydrate bed at 800 m depth during 1997 submersible dives in the northern Gulf of Mexico.
In 1997, two scientists in a submersible pulled up to a block of gas hydrate exposed on the sea floor of the Gulf of Mexico.
The surface of the block was moving, alive with a newly-discovered species of marine worm, now known as Hesiocaeca methanicola, burrowing into the ice.

binomial_name = Hesiocaeca methanicola}} {{Taxobox_end}} Methane clathrate deposits in the ocean floor have been found to be inhabited by polychaete worms of the species '''''Hesiocaeca methanicola'''''.
The worms colonize the ice-methane solid and appear to survive by gleaning bacterium bacteria that in turn metabolize the clathrate.

 Redefining "Life as We Know it" | SpaceRef - Your Space Reference
The flat, pink worms, one or two inches in length, use their appendages like oars to move around the surface of the ice as they graze for the bacteria also living there.
The new worm species, Hesiocaeca methanicola, may have some influence on the formation of natural gas deposits on the sea floor and, if so, on how we go about mining gas as a source of energy.
It has already helped redefine "life as we know it." The bacteria the ice worms eat, and the methane both species grow on, could provide clues about early life on this and other planets.

They are adapted to tolerate high concentrations of crude oil and have also colonized pools of supersaturated brine on the ocean floor.
Gulf is a species of polychaete, Hesiocaeca methanicola, which infests methane hydrates, tolerating poisonous gases and near anoxia apparently to farm bacteria on the surface of the hydrate.
At hydrothermal vents in the eastern Pacific the giant tubeworms have not only adapted to constant exposure to toxic levels of hydrogen sulfide and heavy metals, but their adaptations allow them to grow as fast as any other invertebrate on the planet and flourish in this toxic and ephemeral habitat.
