Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other forms of life.
The bright colors of Grand Prismatic Spring and Yellowstone National Park, are produced by thermophiles, a type of extremophile.. An extremophile (from Latin extremus 'extreme' and Ancient Greek φιλία (philía) 'love') is an organism that is able to live (or in some cases thrive) in extreme environments, i.e., environments with conditions approaching or stretching the limits of what known ...
A number of rodents live at high altitude, including deer mice, guinea pigs, and rats. Several mechanisms help them survive these harsh conditions, including altered genetics of the hemoglobin gene in guinea pigs and deer mice. [33] [34] Deer mice use a high percentage of fats as metabolic fuel to retain carbohydrates for small bursts of energy ...
In warm blooded animals (mammals and birds) this state is referred to as hibernation or torpor (shorter periods of inactivity between awakening); whereas a similar condition in cold-blooded ...
Thermophiles produce some of the bright colors of Grand Prismatic Spring, Yellowstone National Park. A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F).
The most extreme hyperthermophiles live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90 °C for survival. An extraordinary heat-tolerant hyperthermophile is Geogemma barossii (Strain 121) , [ 5 ] which has been able to double its population during 24 hours in an autoclave at 121 °C (hence its name).
It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. The Guinness Book Of World Records listed it in January 1998 [1] as the world's most radiation-resistant bacterium or lifeform. [2] However the archaea Thermococcus gammatolerans is actually the most resistant organism to radiation.
These organisms live everywhere from environments of high acidity or salinity to areas with limited or no oxygen. Scientists show keen interest in organisms with rare or strange talents and in the past 20-30 years extremophiles have been at the forefront with thousands of researchers delving into their abilities.
