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 ...
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).
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 ...
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so.. Chionophiles are any organisms (animals, plants, fungi, etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning "snow", and -phile meaning "lover").
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 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).
Microalgae that live in snow and ice include green, brown, and red algae. Snow algae species such as Chloromonas sp., Chlamydomonas sp., and Chlorella sp. are found in polar environments. [17] [18] Some phytoplankton can tolerate extremely cold temperatures and high salinities that occur in brine channels when sea ice forms in polar oceans.
