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 ...
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.
Tardigrades can withstand 1,000 times more radiation than other animals, [17] median lethal doses of 5,000 Gy (of gamma rays) and 6,200 Gy (of heavy ions) in hydrated animals (5 to 10 Gy could be fatal to a human). [18] Earlier experiments attributed this to their lowered water content, providing fewer reactants for ionizing radiation. [18]
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 ...
Those that can survive a wide range of high-altitude regions are eurybarc and include yak, ibex, Tibetan gazelle of the Himalayas; and leaf-eared mice, vicuñas, llamas of the Andes. Stenobarc animals are those with lesser ability to endure a range of differences in altitude, such as rabbits, mountain goats, sheep, and cats.
As animals like howler monkeys fall dead from trees in Mexico due to high temperatures, conservationists explain their plan to protect wildlife during what is expected to be an unusually hot summer.
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.

At the Phoenix Zoo and Desert Botanical Garden, complex operations to keep animals and plants safe from climate change may help life in the wild. Extreme heat takes a toll on animals and plants ...
