Polar Bear in Shia Kijima Chronicle (2020 October 2nd Games) Polar Bear The polar bear ( Ursus maritimus ) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle , encompassing the Arctic Ocean , its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. [5] [6] A boar (adult male) weighs around 350–700 kg (770–1,540 lb), [7] while a sow (adult female) is about half that size. Although it is the sister species of the brown bear , [8] it has evolved to occupy a narrower ecological niche , with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals , which make up most of its diet. [9] Although most polar bears are born on land, they spend most of their time on the sea ice . Their scientif...
Arctic Tern in Shia Kijima Chronicle (2020 October 2nd Games) Arctic Tern The Arctic tern ( Sterna paradisaea ) is a tern in the family Laridae . This bird has a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe, Asia, and North America (as far south as Brittany and Massachusetts ). The species is strongly migratory , seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later. Recent studies have shown average annual roundtrip lengths of about 70,900 km (44,100 mi) for birds nesting in Iceland and Greenland [3] and about 90,000 km (56,000 mi) for birds nesting in the Netherlands . [4] These are by far the longest migrations known in the animal kingd...
Moose in Shia Kijima Chronicle (2020 October 2nd Games) Moose The moose in North America or elk in Eurasia, ( Alces alces ), is a member of the New World deer subfamily and is the largest and heaviest extant species in the deer family . Most adult male moose have distinctive broad, palmate ("open-hand shaped") antlers ; most other members of the deer family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates . Hunting and other human activities have caused a reduction in the size of the moose's range over time. It has been reintroduced to some of its former habitats. Currently, most moose occur in Canada , Alaska , New England (with Maine having the most of the lower ...
