Polar Bear | The polar bear is native to the Arctic Ocean but the polar bear is thought to be a sub-species of the brown bear. The polar bears scientific name is thought to mean sea bear, probably due to the fact that polar bear often spends long periods of time hunting in or on the freezing Arctic waters. The polar bear
is one of the largest mammals on land with adult males often reaching
over 800kg. The polar bear is the largest species of bear, with only a
few grizzly bear males getting bigger than the average adult polar bear
and these individuals are often polar-grizzly bear hybrids.
Most of the polar bears diet is comprised of seal, meaning the bears spend a lot of time on the frozen sea hunting the seal which is risky work especially when the ice begins to melt. The polar bear
also eats fish but they are not as easy to spot (or catch) as a seal
for a polar bear. The polar bears are often forced to swim for long
distances in search of food, but tend to corner their prey towards the
more frozen ice, as its easier for the polar bear to hunt on solid
ground than it is for the polar bear to hunt in water, particularly as
the seal is such a good swimmer.
Despite its bright white appearance, the fur of a polar bear is in fact clear and not white as it may seem. The polar bear has black skin under its long, thick coat of fur that together with the white from the surrounding snow, creates the illusion of a white coat!
Every year, the polar bear population is decreasing due to a mixture of hunting by humans and the ongoing effects of climate change. As the planet continues to get warmer, the sea ice is thawing earlier which means that the polar bear hunting season is getting shorter and shorter. Those human settlements
within the Arctic Circle are seeing more polar bears every year as the
polar bears are forced to make their way towards what they believe to be
food. Many polar bears end up being shot when they venture close to
towns although some areas are now taking measures to transport the polar
bears away using helicopter rather than killing them.
Scientists have estimated that
if climate change continues to have such a drastic effect on the polar
bear's habitat, then the polar bear could be extinct within the next 30 years.
