. Results of craniological analysis of 111 tiger skulls from Southeast Asian range countries indicate that Sumatran tiger skulls differ from Indochinese and Javan tiger skulls, whereas Bali tiger skulls are similar in size to Javan tiger skulls. The authors proposed to classify the Sumatran and Javan tigers as distinct species, ''P. sumatrae'' and ''P. sondaica'', with the Bali tiger as subspecies ''P. sondaica balica''. In 2015, morphological, ecological, and molecular traits of all putative tiger subspecies were analysed in a combined approach. Results support distinction of the two evolutionary groups continental and Sunda tigers. The authors proposed recognition of only two subspecies, namely ''P. t. tigris'' comprising the Bengal, Malayan, Indochinese, South Chinese, Siberian and Caspian tiger populations, and ''P. t. sondaica'' comprising the Javan, Bali and Sumatran tiger populations. The authors also noted that this reclassification will affect tiger conservation management. The

Hybrids

Captive tigers were bred with lions to create hybrids called liger and tigon. They share physical and behavioural qualities of both parent species. Breeding hybrids is now discouraged due to the emphasis on conservation. The liger is a cross between a male lion and a tigress. Ligers are typically between in length, and weigh between or more. Because the lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female tiger is absent, ligers grow far larger than either parent species. The less common tigon is a cross between a lioness and a male tiger. Because the male tiger does not pass on a growth-promoting gene and the lioness passes on a growth inhibiting gene, tigons are around the same size as their parents. Some females are fertile and have occasionally given birth to

Behaviour and ecology

Social and daily activities

When not subject to human disturbance, the tiger is mainly diurnal. It does not often climb trees but cases have been recorded. It is a strong swimmer and often bathes in ponds, lakes and rivers, thus keeping cool in the heat of the day. Individuals can cross rivers up to wide and can swim up to in a day.

but have much wider home ranges within which they roam. Resident adults of either sex generally confine their movements to their home ranges, within which they satisfy their needs and those of their growing cubs. Individuals sharing the same area are aware of each other's movements and activities. The size of the home range mainly depends on prey abundance, geographic area and sex of the individual. In India, home ranges appear to be while in Manchuria, they range from . In Nepal, defended territories are recorded to be for males and for females. Young female tigers establish their first territories close to their mother's. The overlap between the female and her mother's territory reduces with time. Males, however, migrate further than their female counterparts and set out at a younger age to mark out their own area. A young male acquires territory either by seeking out an area devoid of other male tigers, or by living as a transient in another male's territory until he is older and strong enough to challenge the resident male. Young males seeking to establish themselves thereby comprise the highest mortality rate (30–35% per year) amongst adult tigers. Flying Princess (cropped)

observed a male share a kill with two females and four cubs. Unlike male lions, male tigers allow females and cubs to feed on the kill before the male is finished with it; all involved generally seem to behave amicably, in contrast to the competitive behaviour shown by a lion pride. Stephen Mills described a social feeding event in Ranthambore National Park: Male tigers are generally less tolerant of other males within their territories than females are of other females. Territory disputes are usually solved by intimidation rather than outright violence. Several such incidents have been observed in which the subordinate tiger yielded by rolling onto its back and showing its belly in a submissive posture. Once dominance has been established, a male may tolerate a subordinate within his range, as long as they do not live in too close quarters. The most serious disputes tend to occur between two males competing for a female in oestrus, sometimes fighting to the death. Tiger's Flehmen Response - Kanha National Park

s recorded them hunting in daylight. They generally hunt alone and ambush their prey as most other cats do, overpowering them from any angle, using their body size and strength to knock the prey off balance. Successful hunts usually require the tiger to almost simultaneously leap onto its quarry, knock it over, and grab the throat or nape with its teeth. Despite their large size, tigers can reach speeds of about but only in short bursts; consequently, tigers must be close to their prey before they break cover. If the prey senses the tiger's presence before this, the tiger usually abandons the hunt rather than give chase or battle pre-alerted prey. Horizontal leaps of up to have been reported, although leaps of around half this distance are more typical. One in 2 to 20 hunts, including stalking near potential prey, ends in a successful kill. When hunting larger animals, tigers prefer to bite the throat and use their powerful forelimbs to hold onto the prey, often simultaneously wrestling it to the ground. The tiger remains latched onto the neck until its target dies of

Although they can kill healthy adults, tigers often select the calves or infirm of very large species.

s. After killing their prey, tigers sometimes drag it to conceal it in vegetation, grasping with their mouths at the site of the killing bite. This, too, can require great physical strength. In one case, after it had killed an adult gaur, a tiger was observed to drag the massive carcass over a distance of . When 13 men simultaneously tried to drag the same carcass later, they were unable to move it. An adult tiger can go for up to two weeks without eating, then gorge on of flesh at one time. In captivity, adult tigers are fed of meat a day.

break through at the age of about two weeks. They start to eat meat at the age of eight weeks. At around this time, females usually shift them to a new den. They make short ventures with their mother, although they do not travel with her as she roams her territory until they are older. Females lactate for five to six months. Around the time they are weaned, they start to accompany their mother on territorial walks and are taught how to hunt. A dominant cub emerges in most litters, usually a male. The dominant cub is more active than its siblings and takes the lead in their play, eventually leaving its mother and becoming independent earlier. The cubs start hunting on their own earliest at the age of 11 months, and become independent around 18 to 20 months of age. They separate from their mother at the age of two to two and a half years, but continue to grow until the age of five years. Young females reach sexual maturity at three to four years, whereas males at four to five years. Unrelated wandering male tigers often kill cubs to make the female receptive, since the tigress may give birth to another litter within five months if the cubs of the previous litter are lost. The mortality rate of tiger cubs is about 50% in the first two years. Few other predators attack tiger cubs due to the diligence and ferocity of the mother. Apart from humans and other tigers, common causes of cub mortality are starvation, freezing, and accidents. Generation length of the tiger is about eight years. The oldest recorded captive tiger lived for 26 years. Occasionally, male tigers participate in raising cubs, usually their own, but this is extremely rare and not always well understood.

Man-eating tigers

Wild tigers that have had no prior contact with humans actively avoid interactions with them. However, tigers cause more human deaths through direct attack than any other wild mammal. Attacks are occasionally provoked, as tigers lash out after being injured while they themselves are hunted. Attacks can be provoked accidentally, as when a human surprises a tiger or inadvertently comes between a mother and her young, or as in a case in rural India when a postman startled a tiger, used to seeing him on foot, by riding a bicycle. Occasionally tigers come to view people as prey. Such attacks are most common in areas where population growth, logging, and farming have put pressure on tiger habitats and reduced their wild prey. Most man-eating tigers are old, missing teeth, and unable to capture their preferred prey. For example, the

This decreased the number of attacks only temporarily. All other means to prevent attacks, such as providing more prey or using electrified human dummies, did not work as well.
