* Dogs: Dogs use pheromones, scent signals, to attract potential mates. Females release pheromones to signal their receptivity, while males use scent to mark their territory and attract females.
* Butterflies: Male butterflies release pheromones from special glands on their wings to attract females.
* Moths: Moths rely heavily on scent for courtship. Females release powerful pheromones, which males can detect from miles away, leading them to their mates.
* Elephants: Elephants use scent to communicate, including during courtship. They release urine and dung to signal their readiness to mate, and males also use their musth pheromones to attract females.
* Cats: Cats use urine, feces, and scent glands to mark their territory and attract mates. Females in heat release pheromones that signal their readiness to reproduce.
* Mice: Mice use pheromones to attract mates and communicate their reproductive status.
* Insects: Many insects, like beetles and ants, use pheromones to communicate during courtship.
* Fish: Some fish, like salmon, release pheromones to attract mates and signal their readiness to spawn.
These are just a few examples. The use of smell in courtship is widespread across the animal kingdom!
