What is one animal adaptation you read about in the passage?

In the passage, one notable animal adaptation mentioned is the Arctic fox's thick fur, which provides insulation against the harsh, cold climate of the Arctic. This adaptation not only helps the fox maintain body heat but also changes color with the seasons, offering camouflage against the snow in winter and the tundra in summer. Such adaptations are crucial for survival in extreme environments, allowing the Arctic fox to hunt effectively and evade predators.
