Brown Bear Essay, Research Paper
There are eight different species of bears found throughout the universe:
the monocled bear, the Asiatic black bear, the brown bear ( including
silvertips ) , the polar bear, the Sun bear, the American black bear, the sloth
bear and the elephantine coon bear. Even though most people can separate a polar bear
from a brown bear by the colour of the pelt, a batch of people fail to place all
the differences among those two species. Both bears can be perceived as big,
clumsy and pounding animals with to a great extent built organic structures but short legs, cervixs and
dress suits. Both of them have rounded ears and perceptibly little eyes relative to
their big organic structure size. While both of the bears belong to same household, they have
several profound differences. They live in different geographical countries, differ
in sum of the population, size, physical characteristics, some eating wonts, and
their behaviour toward human existences.
The polar bear is found in all of the polar
parts of the full Northern hemisphere. This includes Russia, Norway,
Greenland, The United States and Canada. Their preferable home ground is in the country
where the northern seas meet the shoreline. In this country, there is a changeless
freeze and melt of the ice. It is estimated that there are presently
someplace between 20,000 and 40,000 polar bears. The polar bear is the largest
member of the bear household, weighing in at between 440 and 1760 lbs with
overall organic structure length 11.5 pess. It can turn much larger, nevertheless. In fact, there
is a record of an grownup polar bear deliberation over 2200 lbs. Polar bears have a
typical all white pelt, which is of import disguise when runing on the ice
battalion. Their existent colour of the tegument is black, which is thought to be an
version for better heat keeping. Compared to the other bears, the cervix of
polar bear is much longer. This makes it easier for them to maintain their caputs
above H2O when swimming. Like those of other bears, the ears of the polar bear
are round. They are, nevertheless, smaller and closer to the caput. This besides helps
the animate being to be an exceeding swimmer. The forepaws on a polar bear are really
big. With a diameter nearing 12 inches and partial webbing between their
toes, polar bears are able to utilize their front pess much like paddles to impel
them quickly through the H2O. Polar bears are first-class swimmers. They are
able to swim distances greater than 60 stat mis without a intermission to rest,
keeping mean velocity of 6 stat mis per hr. On land, they are non every bit speedy as
brown bears and appear to hold traded off velocity for their highly monolithic
forelegs, which they use to interrupt through seal lairs and to toss a big seal out
of the H2O. Polar bears have besides developed big tummies with a capacity of
more than 150 lbs of nutrient. Their digestive system is besides more altered for
treating meat than works stuff because they are about entirely meat
feeders. While out on the ice, their
diet consists largely of marine mammals such
as the annular seals, bearded seals and on occasion a seahorse or narwal. Besides,
in maintaining with their carnivorous nature, the eyetooth dentition, used for prehending and
keeping quarry, are longer, sharper and spaced wider apart than in brown bears.
Polar bear are at the top of the north-polar nutrient concatenation with no natural enemies.
Because of that, compared to other bears, polar bears are the most aggressive
and more willing to see worlds as a quarry. In other words, when they see a
homo, they see a walk-to repast. Consequently the individual attacked is normally
killed unless the bear is killed foremost. The most carnivorous, they are besides the
most patient and determined all of bears. In some cases they may follow a
individual for 100s of stat mis in order to run him down. Out of eight species
polar bear is considered to be the most unsafe to human existences. The brown
bear has the most widespread distribution in the universe of any of the eight bear
species. They are found throughout most of the northern hemisphere including
North America and Eurasia. Their preferable home ground includes mountain woods,
unfastened hayfields and big river vale. It is estimated that there are presently
someplace between 125,000 to 150,000 brown bears throughout the universe. The brown
bear is one largest bear species, yet well smaller than the polar bear.
It weighs between 300 and 860 and can be up to 9.5 pess in entire organic structure length
depending on the handiness of nutrient. Brown bears can run and mount with
considerable accomplishment, velocity and sleight. They are able to achieve velocities of 35
stat mi per hr for a short distance. They are besides capable swimmers. The brown
bear distinguishes itself from other bears by virtuousness of its shoulder bulge, which
is caused by musculuss which are used for delving. The front claws are
about 1.7 times longer than the rear claws and by and large seeable even
from distance. The colour of the carnal varies from a light creamy colour to
about black. Brown bears are omnivorous, eating a assorted diet of grasses,
fruits, bulbs and roots, insects, fish and little animate beings. In few countries there are
known to be marauders of larger animate beings such as reindeer and elk. Each of the
brown bears has a different disposition instead like worlds. Some will assail,
others will non. Some bears are scared of worlds, others will hold a rich person
natural wonder. Brown bears may be really unsafe. However, most of the clip
a they more likely to assail when supporting greenhorns or district. A stalking brown
bear is even a more rare juncture. Even though polar and brown bears have a batch
in common they differ in many ways such as sum of population, size, countries of
life, physical features and attitudes towards people. Scientists have
studied these brilliant animate beings for many old ages, but there is still much to
learn about them. They are really complex and absorbing animals that deserve
great regard.
