Thermococcaceae (lat.) Is a family of archaeans of the Euryarchaeot type ( Euryarchaeota ), the only Thermococcales and Thermococci class [1] [2] (synonymous with Protoarchaea Cavalier-Smith 2002 [3] ). The family includes 3 genera, more than 40 known species, which makes it the largest family in the domain of archaea. Probably, only a small part of species of this class existing in nature has been studied [4] .

Content
Description
They are characterized by a very high temperature of optimal growth (80 ° C higher) at a pH close to neutral (the optimum for most lies within 6-8) and salinity close to the salinity of sea water. The most frequent habitats are underwater hydrothermal sources. Representatives of the genus Thermococcus are also found in the terrestrial hydrotherms of New Zealand. There is currently no information on the habitat of thermococci in aerobic and low-temperature ecosystems and in environments with high or low pH [4] .
