In taxonomy, Methanococcus is a genus of the Methanococcaceae.^[1]

Methanococcus is a genus of coccoid methanogens. They are all mesophiles, except the thermophilic M. thermolithotrophicus and the hyperthermophilic M. jannaschii. The latter was discovered at the base of a “white smoker” chimney at 21°N on the East Pacific Rise^[2] and its was the first archaeal genome to be completely sequenced, revealing many novel and eukaryote-like elements.^[3]
