China's 13th Arctic expedition team observed polar bears at about 8 p.m. Beijing time on July 31.
"I was about to do the weather observation when I suddenly saw a moving thing on the ice, and it turned out to be a polar bear," said Sun Hulin, a meteorological forecaster for China's 13th Arctic scientific expedition mission.
"I feel very excited to see a wild polar bear for the first time," said Zhu Yongtao, a member of China's 13th Arctic scientific expedition mission.
The polar bear is the largest of all bears and one of the most iconic mammals in the Arctic. To adapt to the extremely cold environment here, they have a thick layer of fat that provides insulation and warmth, effectively stopping heat loss. On the other hand, the thick hair of polar bears can form an insulating layer on the surface of their bodies, effectively isolating them from the cold environment. The white fur of the polar bear also helps it camouflage itself in the snow to avoid being detected by predators. In addition, polar bears have a special circulatory system and behavioral habits.
