scent mark

In zoology, a scent mark is a chemical signal used by animals, primarily mammals, to communicate with others of the same species. These marks are often deposited from specialized glands, such as preorbital or anal glands, onto objects in an animal's territory. The complex chemical mixtures within these secretions can convey information about individual identity, reproductive status, and territorial boundaries.123

Scent marking plays a crucial role in territorial behavior, helping animals advertise their presence and deter intruders. For instance, antelopes use secretions from their preorbital glands to mark territory borders, while carnivores like civets use anal gland secretions. The persistence and composition of these scent marks are vital for effective communication, allowing recipients to gauge the recency of an intruder. These chemical signals can also be involved in reproduction, social interactions, and even alarm signaling.143
