An Alpine chough in flight at 3,900 m (12,800 ft). Organisms can live at high altitude, either on land, in water, or while flying.Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
The few animals that live on the mainland are birds such as Antarctic terns, grey-headed albatross, imperial shag, snowy sheathbill and the most well known inhabitant of Antarctica, penguins. The inhospitable environment helps to deter predators ; the few predators that hunt on the mainland, including the south polar skua and the southern giant ...
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 ...
This system is used in many unrelated animals: ants, bees, and wasps, termites, naked mole-rat, Damaraland mole-rat, Synalpheus regalis shrimp, certain beetles, some gall thrips and some aphids. [191] Oxygenate blood came about in unrelated animals groups: vertebrates use iron and crustaceans and many mollusks use copper . [192]
The large animals often migrate between the two, and smaller animals are expected to be able to spread via underwater currents. [8] However, among smaller marine animals generally assumed to be the same in the Antarctica and the Arctic, more detailed studies of each population have often—but not always—revealed differences, showing that ...
Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. Throughout the animal kingdom, adaptations have evolved for every stage of this struggle, namely by avoiding detection, warding off attack, fighting back, or escaping when caught.
Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
Antarctica is one of the most physically and chemically extreme terrestrial environments to be inhabited by lifeforms. [1] The largest plants are mosses, and the largest animals that do not leave the continent are a few species of insects. Microbiome on the High Antarctic Plateau
