Defensive adaptations are traits or behaviors that help organisms protect themselves from predators or environmental threats. These adaptations can include physical features, such as the sharp spines of a porcupine or the tough shells of tortoises, which provide a barrier against attacks. Other adaptations may involve camouflage, allowing animals like chameleons to blend into their surroundings and avoid detection. In addition to physical defenses, some species employ behavioral strategies for protection. For example, skunks release a foul-smelling spray when threatened, deterring potential predators. Similarly, many animals, such as deer, use flight responses to escape danger quickly. These adaptations enhance survival in the wild.
