Animal insulation refers to the natural adaptations that certain animals have developed to maintain their body temperature in extreme environments. This can include thick fur, blubber, or specialized feathers that trap heat and provide protection against cold weather. For example, polar bears have a layer of fat beneath their skin that helps insulate them from frigid temperatures. In addition to physical adaptations, some animals also use behavioral strategies for insulation. Many species, such as penguins, huddle together to share warmth during harsh conditions. These adaptations are crucial for survival, allowing animals to thrive in diverse habitats, from icy tundras to arid deserts.
