Reindeer have adapted to the extreme cold and so have their hooves. Caribou hooves change with the season, becoming more padded and softer in the summer for stepping on grass and twigs, while they ...
The mountain reindeer has several physiological adaptations to cope with different environmental temperatures. Reindeer have hemoglobin that allows for high oxygen unloading even at very cold temperatures. [1] This is essential because reindeer limbs are often kept much colder than core body temperature, a phenomenon known as regional ...
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so. Chionophiles are any organisms ( animals , plants , fungi , etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning " snow ", and -phile meaning "lover").

Reindeer are a type of deer that has evolved to endure harsh winters in freezing climates. They are the only deer species with hair completely covering their nose. This helps warm incoming cold ...
