Halophiles

At the DNA level, the halophiles exhibit distinct dinucleotide and codon usage.

Halophiles may use a variety of energy sources.

In order to survive the high salinities, halophiles employ two differing strategies to prevent desiccation through osmotic movement of water out of their cytoplasm.

Most halophiles are unable to survive outside their high-salt native environment.

Of particular note are the extreme halophiles or haloarchaea (often known as halobacteria ), a group of archaea, which require at least a 2 M salt concentration and are usually found in saturated solutions (about 36% w/v salts).

Similarly, if it were too salty, only extreme halophiles could survive in its environment.

Some hypersaline lakes are a habitat to numerous families of halophiles.

These are nearly exclusively hyperthermophiles or extreme halophiles.
