Territoriality is a behavior in which an animal defends a bounded physical space against encroachment by other individuals, usually of its own species. Territory defense may involve direct aggression or indirect mechanisms such as scent marking or singing. In many vertebrates and some invertebrates, territoriality may limit density. For this, territory space becomes the resource for which individuals compete. For example, cheetahs are highly territorial because they use chemical communication to warn other cheetahs of their territorial boundaries.
