10 Surprising Ways Animals Use Scent to Send Messages

6. Parental Care: Scent Bonds

For many animals, scent is the key to recognizing and caring for their young. In crowded colonies or herds, where visual cues might not be reliable, this ability is a lifesaver. Seals, for example, rely on their pup’s unique scent to reunite after long hunting trips, ensuring they nurse the right offspring. Sheep do the same—ewes memorize their lamb’s scent soon after birth, preventing mix-ups and strengthening their bond. This olfactory connection isn’t just about recognition; it’s a survival mechanism. By using scent to identify and care for their young, parents ensure their energy and resources go exactly where they’re needed, giving their offspring the best possible start in life.
