Archaea in extreme environments

Archaea are microscopic organisms that belong to their own domain of life, distinct from bacteria and eukaryotes. They are remarkable for thriving in extreme environments where most other life forms cannot survive, such as hot springs, deep-sea vents, acidic lakes, and salt flats. These microorganisms have unique biochemical features allowing them to withstand high temperatures, extreme pH levels, and high salinity. Their ability to live in such harsh conditions provides insights into the resilience of life on Earth and possibly other planets, and they play important roles in global ecosystems and biogeochemical cycles.
