Hunting extreme microbes that redefine the limits of life
Briefly

Intraterrestrials by Karen G. Lloyd presents a captivating exploration of microorganisms thriving in extreme environments like deep ocean crusts and permafrost. Through her experiences as a geomicrobiologist, Lloyd reveals astonishing examples of life that can survive in extreme conditions, including those in suspended animation for millennia. With accessible writing and engaging narratives about her fieldwork, she illustrates the complexities and challenges of studying these 'intraterrestrial' microbes. The book emphasizes the significance of this research and parallels with the search for extraterrestrial life, showcasing the wonder of Earth's hidden ecosystems.
Lloyd brings the reader along as she collects gas-rich sediments and microbial mats aboard a deep-sea submersible in the Gulf of Mexico.
The intraterrestrials in the title echo the extraterrestrials that might populate other planets and moons. But there's no need to search far for alien-like life.
