The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, such as the alga Dunaliella salina and fungus Wallemia ichthyophaga. Some well-known species give off a red color from carotenoid compounds, notably bacteriorhodopsin. Halophiles can be found in water bodies with salt concentration more than five times greater than that of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds. They are theorized to be a possible candidate for extremophiles living in the salty subsurface water ocean of Jupiter's Europa and other similar moons.

Chott Melrhir also known as Chott Melghir or Chott Melhir is an endorheic salt lake in northeastern Algeria. It the westernmost part of a series of depressions, which extend from the Gulf of Gabès into the Sahara. They were created between Miocene and Early Pleistocene as a result of compression accompanying the formation of the Atlas Mountains. With the maximum area of about 6,700 km2 (2,600 sq mi), Chott Melrhir is the largest lake in Algeria. It lies almost entirely below the sea level and contains the lowest point in Algeria, −40 meters. Its size varies over the year and is usually larger than 130 km (81 mi) from east to west. The nearby cities are Biskra, El Oued and Touggourt.
