Organisms in extreme conditions...

I decided to do my blog on halophiles. "Halophiles are aerobic microorganisms that live and grow in high saline/salty environments. The saline content in halophilic environments is usually 10 times the saline/salt content of normal ocean water. Some environments that halophiles live in are the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea. These microorganisms use osmotic pressure and chemical substances like sugars, alcohols, amino acids to help control the amount of salt inside the cell. Halophiles are like other extremophiles because the proteins inside the microorganisms play the most important role of making it possible for them to survive in extreme saline/salty environments" (Oracle Think Quest).
