Territoriality

Many different species exhibit territorial behavior, because it offers several advantages to the territorial animal. Walrus battling over a hauling-out spot, Bristol Bay, Alaska. JLM Visuals.

Thus it can react quickly to dangerous situations without having to actively seek hiding places or defensible ground. By spacing out potential competitors, territoriality also prevents the depletion of an area's natural resources. This regulation of population density may also slow down the spread of disease. In addition, territorial behavior exposes weaker animals (which are unable to defend their territory) to predation, thereby promoting a healthy population.
