Nanoarchaeota

Nanoarchaeota are a group of tiny microorganisms within the domain Archaea, which are single-celled life forms distinct from bacteria and eukaryotes. They are extremely small, often less than 0.5 micrometers, and typically inhabit extreme environments like geothermal hot springs. Nanoarchaeota have very simple structures and rely on other organisms, such as their host archaea, for nutrients and metabolic functions, functioning in a symbiotic or parasitic relationship. Their study helps scientists understand microbial diversity, adaptability to harsh conditions, and the evolution of life in extreme environments.
