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 this state, the animals use much less energy than when active and are able to overwinter until onset of more favorable conditions in spring. In warm blooded animals (mammals and birds) this ...
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.
The Most Extreme is a documentary television series on the American cable television network Animal Planet.It first aired on July 7, 2002. Each episode focuses on a specific animal feature, such as strength, speed, behavior, anatomy, or diet, and examines and ranks ten animals that portray extreme or unusual examples of that quality.
In the more extreme areas of the mainland, such as the cold deserts, food webs are sometimes restricted to three nematode species, only one of which is a predator. [13] Many invertebrates on the subantarctic islands can live in subzero temperatures without freezing, whereas those on the mainland can survive being frozen. [14]
An extreme environment is a habitat that is considered very hard to survive in due to its considerably extreme conditions such as temperature, accessibility to different energy sources or under high pressure. For an area to be considered an extreme environment, it must contain certain conditions and aspects that are considered very hard for ...
