    3. 3. Biologists assume the polar Bear population consists of 19 suBpopulations andapproximately 20,000–25,000 polar Bears worldwide.
    4. 4. Polar bears are native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses.
    5. 5. They are the worlds largestland carnivore and also the largest bear with adult males weighingaround 350–680 kg (770–1,500 lb), and females one-half that size.
    6. 6. Polar bears are able todetect seals nearly 1 miaway and buried under 3 ft of snow.
    7. 7. Polar bears are insulated by up to 10 cm of blubber.Therefore, they still overheat in rather cold temperatures (10°C). Therefore they are almost invisible to infrared
    8. 8. • the legs are stocky • the ears and tail are small• their paws are very large (an adult’s can measure 30 cm across.) • claws are short and stocky: deeply scooped on the underside • have 42 teeth.
    9. 9. The polar bear is an excellent swimmer.They have been spotted 200 mi out in open Arctic waters.
    10. 10. Polar bears maintain a speed that ranges from walking at 3.5 mph to sprinting at 25 mph.

    18. 18. Polar bears rarely live beyond 25 years. Theoldest polar bear on record died at the age of
    19. 19. The polar bear is classified as a  vulnerable species, with eight of thenineteen polar bear subpopulations in decline.
    20. 20. Some scientists believe the population decline of polar bears is caused by rising temperature climates, the consumption of garbage, hunting, and land sales for gas and oil development.
