An adaptation is any trait that helps an animal or plant survive in its habitat. Adaptations are helpful only in the habitat for which an animal is adapted. A freshwater newt, used to living in or near water, wouldn’t survive long in the desert.

Diet, behavior, physical anatomy, and even physiology (internal mechanisms), are ways animals adapt to their surroundings. Many living things have evolved unique ways of dealing with the problems of survival. An animal’s adaptations develop over a very long time and can pass to their children, such as an eagle’s keen sense of sight or a hummingbird’s long beak
