Polar bears are the largest land carnivores on the planet,
equaled just by the Kodiak brown bears of southwestern Alaska. Polar bears sit
at the highest point of the natural way of life in the organically rich Arctic.
The most rapacious of the bear species, polar bears feed principally on the fat
of ice-subordinate seals. The remaining parts of these seals give nourishment
to numerous other Arctic natural life species, giving polar bears a fundamental
part in their biological system.
Polar bears are marine warm blooded animals, and invest a
lot of their energy in Arctic ocean ice. Numerous adjustments make polar bears
exceptionally suited to life in cold living spaces. Their hide is thicker than
some other bears' and covers even their feet for warmth and footing on ice. A
thick layer of fat underneath their hide gives lightness and protection. The
long neck and thin skull of the polar bear presumably help in streamlining the
creature in the water while warming the air that they inhale, and their front
feet are substantial, level and paddle like, making them astounding swimmers.
Range and Habitat:
Polar bears are just found in the Arctic. The most vital
natural surroundings for polar bears are the edges of pack ice where streams
and wind cooperate, shaping a constantly softening and refreezing network of
ice fixes and drives (open spaces in the sea between ocean ice). These are the
territories of where polar bears can locate the best number of seals.
As the ocean ice advances and withdraws each season, individual
polar bears may travel a large number of miles every year to discover
nourishment. Polar bears are appropriated all through the Arctic district in 19
subpopulations, including Alaska, Canada, Russia, Greenland and Norway.
Behavior:
The polar bear is nomadic. It goes to discover its
sustenance. It frequently takes after seals as they relocate south. The polar
bear as a rule ventures alone and remains close to the water's edge. It is a
decent swimmer and invests a ton of energy in the water chasing for seals. The
polar bear can swim similarly as 60 miles without resting and can swim at paces
of up to six miles 60 minutes. It can plunge to profundities of 15 feet and can
remain submerged for around two minutes.
Diet:
Unlike other bear species, polar bears are only meat eaters.
They basically eat ringed seals, however may likewise eat bearded seals. Polar
bears chase seals by sitting tight for them to rise to the top of ocean ice to
relax. At the point when the seal nears the surface, the polar bear will chomp
or snatch the seal and force it onto land to bolster. They additionally eat
walruses and whale remains. Polar bears will seek out winged creature eggs and
other sustenance sources, however none of these are sufficiently plenteous to
manage the extensive weight and thick populaces of polar bears.
Another indispensably essential nourishment source in many
zones are seal little guys that are conceived and live in nooks in the Arctic
ice. The polar bear recognizes these sanctums by smell and different markers
and jumps however the top of the cave to catch the youthful seals. In Hudson
Bay, the accessibility of seal little guys in the spring is progressively
restricted by before liquefying of ice. In the Arctic, polar bears are at the
highest point of the evolved way of life; they eat everything and nothing
(aside from local seekers) eats them. 
Reproduction:
Pregnant polar bears need to eat a great deal in the mid
year and fall develop enough fat stores to survive the denning time frame. They
search out maternity nooks in October or November. Most maternity sanctums are
situated ashore where snow collects including along seaside feigns, waterway
banks or weight edges on ocean ice. Sows bring forth generally 1 or 2 one-pound
whelps and after that medical caretaker them until the point when they reach
around 20-30 pounds before rising up out of the nook in March or April. The
youthful are conceived from November through January while the moms are
sleeping. Offspring will stay with their moms for barely 2 years. Female polar
bears can deliver five litters in their lifetime, which is one of the most
minimal conceptive rates of any warm blooded animal.
Mating Season: Late March - May
Growth: About 8 months with deferred implantation
Litter size: 1 - 4 whelps; however 1 or 2 fledglings is
generally normal
Do Polar Bears attack people?
Polar bears by and large will stay away from people, yet as
the general ice conditions thin they will be pushed promote outwards from the
Artic towards human homes. The bears with normal contact with human settlements
will examine junk dumps for simple nourishment. Seals are considerably simpler
prey, with a far more noteworthy reward for the exertion. Risky experiences
with people are uncommon; however when sufficiently hungry, polar bears will in
fact assault and eat people. As more polar ice for all time softens, the
quantity of these experiences is relied upon to increment.
