Field Notes
Description:
The polar bear is the newest of the eight bear species, and scientists believe that the polar bear evolved about 200,000 years ago from brown bear ancestors. Unfortunately, due to loss of polar ice they are now having to swim up to 2-3 times longer distances, which takes a toll on their energy and fat storage. They are now listed as vulnerable.
Habitat:
Throughout the Arctic.
Notes:
Photos taken at San Diego Zoo.
