Pangolins mark territory with anal gland secretions and scent markings. Though silent, these chemical signals communicate presence to other pangolins. Territoriality prevents competition for scarce insects. They often avoid direct confrontation by relying on scent cues. Markings are left on trees, rocks, or soil. Both males and females engage in marking. It’s an effective communication system in dense forests.
Territorial behavior reduces resource conflict. Chemical signals prevent dangerous encounters.
It shows communication need not involve sound. Chemical language can efficiently maintain social order.
Pangolins may patrol marked territories nightly to reinforce boundaries.
