Quick Summary

A piezophile, also known as a barophile, is an organism that thrives in environments with high hydrostatic pressure. These organisms are a type of extremophile, meaning they are adapted to survive and grow optimally under extreme conditions.1

Piezophiles are primarily prokaryotic, consisting of archaea and bacteria, though a few eukaryotic examples exist. They are defined by their optimal growth conditions, which in this case, is high pressure.1

The study of piezophiles is important for understanding the limits of life on Earth and may offer insights into the potential for life in extreme environments elsewhere in the solar system.1
