Intraterrestrials

In 'Intraterrestrials,' Karen Lloyd takes readers on a journey to the planet's most extreme and hidden environments—from deep ocean methane seeps to Arctic permafrost and high-altitude volcanoes—where scientists have discovered microbial life forms that defy conventional expectations.

These 'intraterrestrials' thrive in boiling water, pure acid, and even bleach, and some can 'breathe' rocks or electrons, living for hundreds of thousands of years.

Lloyd blends captivating storytelling with the latest science, showing how these discoveries not only challenge our most basic assumptions about life on Earth but also inform the search for life on other planets and the future of our own biosphere.
