Animal adaptations are special features or behaviors that help animals survive in their environments. These adaptations can be physical, like the thick fur of a polar bear that keeps it warm in icy habitats, or behavioral, like the migration patterns of birds that allow them to find food and suitable climates. Different animals have evolved unique adaptations based on their surroundings. For example, camouflage helps animals like the chameleon blend into their environment to avoid predators, while the long neck of a giraffe allows it to reach high leaves in trees. These adaptations are essential for survival and reproduction.
