Presented By: Youstena Zaki and Diana Hanna
Order: Carnivora
Family: Ursidae
Genus: Ursus Maritimus

2. Introduction:
 During this presentation, we will discuss
several topics regarding polar bears.
 Topics such as physical
characteristics, habitat, adaptation, and
life of the bears.
 As well as, discussing the environmental
threats that the bears face.

3. Physical Characteristics
 Weight 550-1700 lbs for
adult males, and 200-700
Ibs for adult females.
 Have small heads.
 Good sense of smell to
detect prey.
 Five-toed paws, helps
move around.
 White thick coat which.
 They have two layers of
hair.

4. Habitat and Distribution
 Arctic sea ice, water, islands.
Alaska, Canada, Russia, Greenland, Norway.
(Stirling)
 Land masses around the edge of the polar
basin.
 Polar bears migrate seasonally, staying with
the movement of ice.

5. Adaptation
 Strong swimmers.
 Long bodies allows
with fat under their
skin allows them to
float in the water.
 The thick layer of
fur, keep them
insulated.

6. Longevity of polar bears
2010, USFWSAlaska
 Live 20-30 yrs.
 No predators, but other old bears.
 Cubs can be killed by wolves.
 Newborn-Cannibalized by malnourished
parents.
 Some bears die of starvation.
(Polar Bear-Ursus…)

7. Diet and Eating Habits
 Mainly ringed and bearded
seals.
 Harp
seals, walrus, whales.
 If no food is available they
eat what they find.
 They need an average of 2
Kg of fat per day.
 “Still Hunting.” -They 2010, Maia C.
remain still waiting for the
seals to come to surface
and as they come up the
bears attack the head.
This method takes about
an hour.

8. Hunting & Environment Threats
 Hunted for
food, clothing.
 Hunting is regulated by
the government in
US, Canada, and
Greenland. (Witze)
 Climate change-
decrease in
temperature.
 Oil spills damages fur-no
insulation.
 PCB and DDT.
(Revkin)

9. Conclusion:
 We hope that you at least learned one new
fact and increased your knowledge
regarding polar bears.
 As the weather gets warmer and you are at
the beach enjoying the sun. Be sure to
remember how the polar bears are
negatively effected due to the melting of ice
sheets.
 We also ask everyone to try their best to
minimize the oils spills that could
potentially reduce the amount of bears in
the world.
