To answer your question, I need to know which animal you're interested in! Tell me the animal's name, and I can describe its physical adaptations. For example:
* Polar bears have thick layers of blubber and fur to stay warm in the Arctic.
* Camels have long eyelashes and nostrils that can close to protect them from sandstorms in deserts.
* Fish have gills to breathe underwater.
