is a halophilic (salt-loving) archaeon that grows in salt concentrations near or at saturation. Although isolated from salted fish a century ago, it was the 1971 discovery of bacteriorhodopsin, the light-driven proton pump, that raised interest in across a range of disciplines, including biophysics, chemistry, molecular evolution and biotechnology. have since contributed to numerous discoveries, such as advances in membrane protein structure determination and the first example of a non-eukaryal glycoprotein. Work on , one of the species used to define Archaea, has also elucidated molecular workings in the third domain. Finally, presents creative solutions to the challenges of life in high salt.
