The tiger is regarded as the king of the jungle in most parts of Asia, because its forehead has a marking which resembles the Chinese character 王, which means “king”
Among the big cats, only the tiger and jaguar are strong swimmers; tigers are often found bathing in ponds, lakes and rivers.
Adult tigers are fiercely territorial. The size of a tiger’s home range mainly depends on prey abundance, and, in the case of male tigers, on access to females. A tigress may have a territory of 20 km², while the territories of males are much larger, covering 60–100 km².
While females can at times be aggressive towards other females, their territories can overlap and they do tolerate each other. Males, however, are usually intolerant of other males within their territory. Because of their aggressive nature, territorial disputes can be violent, and may end in the death of one of the males.
To identify his territory, the male marks trees by spraying urine and anal gland secretions on trees as well as by marking trails with scat. Males show a grimacing face, called the Flehmen response, when identifying a female’s reproductive condition by sniffing their urine markings.
