Quick Summary

Cenarchaeum symbiosum is a prokaryotic organism belonging to the domain Archaea. Archaea are single-celled microorganisms distinct from bacteria and eukaryotes, characterized by their unique molecular structures.1

C. symbiosum is notable for its symbiotic relationship with a sponge, and it was the first non-thermophilic Crenarchaeota to be successfully cultured in a laboratory setting. This organism is considered for classification within the Thaumarchaeota lineage. Archaea, as a group, are known for inhabiting extreme environments, but they are also found in a wide variety of global habitats and play crucial ecological roles.1
