The emission of a defensive musk by skunks is typically triggered by perceived threats. This action serves as a deterrent to potential predators or aggressors, providing the skunk with an opportunity to escape. For example, a skunk might discharge its scent glands when confronted by a dog or another animal it considers a danger.
The ability to deploy this noxious spray is vital for a skunk’s survival. It allows them to navigate environments populated by larger, more powerful creatures. Historically, this defense mechanism has enabled skunks to thrive across various landscapes, contributing to their ecological role and population stability.
