=// __ Extremophiles (Ice Lovers) __  //=



Who are the extremophiles? They could survive in places like salty, hot, and cold conditions. They can even survive in space! Extremophiles can even survive any type of weather, from freezing cold places to boiling hot. They can survive a whole trip through space and back! Wow, but who are these extremophiles? They are archaebacteria, also known as //Archaea//.

Ice lovers are from the archibactiria kingdom. The live in some of the coldest conditions on earth such as Lake Vostok. Lake Vostok is a large freshwater lake that has been frozen for about a million years. It is there that you can find ice loving archaebacteria. You can also find them in outer space. Archaebacteria is a single celled organism which means it cannot be seen with the naked eye. Archaebacteria has a cell wall. This allows it to survive in harsh conditions such as the freezing weather. Archaebacteria is known as extremophiles because they live in very harsh conditions all over the world such as very hot areas and very cold places. Archaebacteria is also prokaryotic which means it has no nucleus. Richard Hoover, a scientist from NASA, found ice cores from a lake that contained archaebacteria. These organisms, (archaebacteria) can live in very cold environments. Archaebacteria can live in ice cores for up to 400 thousand years. Some archaebacteria have been found in lakes that are almost two miles deep. These extremely cold organisms can go into suspension to create a level where activity is put on hold. Archaebacteria is so magnificent that it can even live in space.
