Extremophiles!!

Not every life on this planet lives the same way. Certain species thrive in alternative environments. These species are called extremophiles. A few examples follow:

Halophiles: organisms that require at least 0.2 M concentration of salt (NaCl) for growth

Acidophiles: organisms that grow optimally at a pH of 3 or below



Xerophile: an organism that can grow in extremely dry, dessicating conditions

 

Normally, organisms cannot live much less thrive in these arid, acidic or salty environments, but these special extremophiles show that life can survive in these extreme conditions. Because these particular organisms have evolved to survive extremes, almost anything is possible with life!
