how many species of penguin are found in the arctic circle
Penguin Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin actually live so far south. Several species live in the temperate zone;[49] one, the Galápagos penguin, lives as far north as the Galápagos Islands, but this is only made possible by the cold, rich waters of the Antarctic Humboldt Current that flows around these islands.[50]
Recluse spider There are about 100 species of Loxosceles.[3]
Penguin Penguins for the most part breed in large colonies, the exceptions being the yellow-eyed and Fiordland species; these colonies may range in size from as few as a 100 pairs for gentoo penguins, to several hundred thousand in the case of king, macaroni and chinstrap penguins.[58] Living in colonies results in a high level of social interaction between birds, which has led to a large repertoire of visual as well as vocal displays in all penguin species.[59] Agonistic displays are those intended to confront or drive off, or alternately appease and avoid conflict with, other individuals.[59]
Daylily The World Checklist of Selected Plant Families recognizes 19 species as of September 2014[update]:[1]
Polar bear There are 19 generally recognized, discrete subpopulations, though polar bears are thought to exist only in low densities in the area of the Arctic Basin.[36][38] The subpopulations display seasonal fidelity to particular areas, but DNA studies show that they are not reproductively isolated.[33] The thirteen North American subpopulations range from the Beaufort Sea south to Hudson Bay and east to Baffin Bay in western Greenland and account for about 54% of the global population.[39]
