Thermococcus is a spherical hyperthermophilic
euryarchaeote indigenous to anoxic thermal waters in various locations throughout the world.
The spherical cells contain a tuft of polar flagella and are thus highly motile.
Thermococcus is an obligately anaerobic chemoorganotroph that grows on proteins and other complex organic mixtures (including some sugars) with S
0 as electron acceptor at temperatures from 70-95°C.
