   Halophilic Organisms
   Organisms classified as halophiles (salt-lovers) have evolved specialized mechanisms to cope with high ionic concentrations. Within the domain Archaea, certain haloarchaea maintain osmotic balance not by actively pumping ions out, but by accumulating massive internal concentrations of compatible solutes, such as ectoine, or by selectively replacing intracellular $\text{Na}^+$ and $\text{Cl}^-$ with $\text{K}^+$ and $\text{Cl}^-$.
