Habitat
. The artic is on the top of the earth
. The polar bear is a mammal that lives on
Arctic
.The entire circumpolar Arctic region is polar
bear habitat
It’s appearance
• The polar bear is the largest bear in the
world.
• Adults weigh 650 to 1100 pounds (295 kg
to 498 kg )
Males are larger than females.
A polar bear's coat can be from white to
yellowish in colour.
• When the bears come ashore in the
summer they eat plants and berries.
• They have thick oily
fur coats and a layer
of fat under their skin.
When bears come out
of the water they
shake the water off
their coats.
The polar bear is so
strong it can kill an
animal with one blow
to the head
Its foods
In late summer and early autumn the
bears go along the coastline looking for
dead whales and dead walruses. They
also eat lemmings, arctic foxes and birds.
Their favourite food is the ringed seal. The
polar bear waits by the seal's breathing
holes in the ice and quickly snatches the
seal when it pokes its head out of the hole.
What it can do
• Polar bears are able to swim in the icy
Arctic Ocean without dieing of the cold
temperatures.
• The polar bear is nomadic. It travels to
find its food.
How many are left?
• Scientists estimate that there's about 22,000
to 27,000 polar bears left on the Artic
• The impact of man is decreasing the
population of the polar bear. This happening
by green house gasses (global warming)
hunting , less of food and other human impacts
The human impact
• The impact on the polar bears population
is decreasing every year by the green
house gasses and hunting by humans.
The way the problem is being dealt with
the future of the polar bears could be few.
The Food Chain
Future of polar bears
• The future of the polar bears can be
changed if the problems of the polar bears
are resolved. The polar bears will be around
for years to come we must stop the killing
of the polar bears.
Life and death
.Polar bears can live 20 to 30 years, but only
a small proportion of polar bears live past
15 to 18 years
. Evidence of human polar bear hunts have
been found in 2,500- to 3,000-year-old
ruins. Arctic peoples have traditionally
hunted polar bears for food, clothing,
bedding, and religious purposes.
how the polar bears keep warm
• Polar bears have white, thick, creamy
fur that helps them keep warm and is a
good camouflage on the snowy
landscape. An average male polar bear
weighs over 1,000 pounds and is about
ten feet long. A female polar bear is
much smaller. They are about eight feet
long. Sometimes Alaskan polar bears
weigh over 1,500 pounds.
