Younger, leaner bears are the best runners and are able to cover two kilometers without stopping. Older and larger bears, on the other hand, quickly overheat. This overheating phenomenon is very common in polar bears, as they expend more than twice the energy of most other mammals when walking or running—showing higher than average increases in temperature and oxygen consumption.</p> Tue, 21 Feb 2017 04:41:16 +0000 Joe Schwarcz PhD 1503 at /oss
