The animals do differ by the temperature. In the Arctic some invertebrates include spiders, mites, mosquitoes and flies. In warmer areas of the polar regions moths, butterflies and beetles can be found. Some of the larger animals that exist are foxes, wolves, rabbits, hares, polar bears, reindeer/caribou. There are various bird species that ...
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females ...
Polar bear in Manitoba, Canada. November 2004. Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans). In the coldest years, sea ice can cover around 13 percent of the Earth's total surface at its ...
Copepod. Copepods (/ ˈkoʊpəpɒd /; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (living in the water column), some are benthic (living on the sediments), several species have parasitic phases, and some continental species may live in limnoterrestrial ...
Antarctic microorganism. Appearance. 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.
Some phytoplankton can tolerate extremely cold temperatures and high salinities that occur in brine channels when sea ice forms in polar oceans. Some examples are diatoms like Fragilariopsis cylindrus, Nitzchia lecointeii, Entomoneis kjellmanii, Nitzchia stellata, Thalassiosira australis, Berkelaya adeliense, and Navicula glaciei.

Eurytherm. A eurytherm is an organism, often an endotherm, that can function at a wide range of ambient temperatures. [ 1 ] To be considered a eurytherm, all stages of an organism's life cycle must be considered, including juvenile and larval stages. [ 2 ] These wide ranges of tolerable temperatures are directly derived from the tolerance of a ...
Arctic ecology. A sunset in the arctic region. Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2] While the taiga has a more moderate climate and ...
