Arctic ground squirrel

The Arctic ground squirrel is a small rodent native to northern North America, known for its remarkable ability to survive extreme cold. During winter, it hibernates in burrows, lowering its body temperature close to freezing and minimizing metabolic activity to conserve energy. It can withstand some of the coldest temperatures experienced in the Arctic, including prolonged periods of freezing. This adaptation allows it to endure harsh environments where food is scarce, making it a fascinating example of how animals adapt to extreme climates.
