What are the physical adaptations of the lemming?

Lemmings have several physical adaptations that help them survive in their harsh, cold environments. They possess a thick fur coat that insulates against freezing temperatures, and their fur changes color seasonally, providing camouflage against snow and terrain. Additionally, lemmings have short, stocky bodies and small ears, which help minimize heat loss, as well as large, sharp incisors for gnawing on tough vegetation. These adaptations enable them to thrive in the tundra and subarctic ecosystems where they live.
