1 Malayan tiger (. Jacksoni luo., 2004 There is no clear difference between the malayan and the Indochinese tiger in pelage or skull size. 41 It was proposed as a distinct subspecies on the basis of mtdna and micro-satellite sequences that differs from the Indochinese tiger. 15 Males range in total length from 190280 cm (75110 in) and weigh between.2 to 129.1 kg (104 to 285 lb while females range from 180260 cm (71102 in) and 24 to 88 kg (53 to 194 lb). 42 The population was roughly estimated at 250 to 340 adult individuals in 2013, and likely comprised less than 200 mature breeding individuals at the time. 43 The geographic division between Malayan and Indochinese tigers is unclear as tiger populations in northern Malaysia are contiguous with those in southern Thailand. 1 In Singapore the last tiger was shot in 1932; tigers are considered extirpated since the 1950s.

34 Males have a head and body length of between 190 and 230 cm (75 and 91 in) and weigh between 180 and 306 kg (397 and 675 lb while females average enemy 160 to 180 cm (63 to 71 in) and 100 to 167 kg (220 to 368 lb). Tail length is about 60110 cm (2443 in). 28 This population inhabits the Amur - ussuri region of Primorsky krai and Khabarovsk Krai in far eastern Siberia, with a small population in Hunchun National Siberian Tiger Nature reserve in northeastern China near the border to north Korea. 37 38 It is extinct in Mongolia, north Korea, and south Korea. 1 In 2005, there were 331393 adult and subadult Siberian tigers in the region, with a breeding adult population of about 250 individuals., there was an estimated population of 480-540 individuals in the russian Far East. 40 Indochinese tiger (. Corbetti mazák, 1968 21 The Indochinese tiger was described as being smaller than the bengal tiger and as having a smaller skull. Males average 108 inches (270 cm) in total length and weigh between 150 and 195 kg (331 and 430 lb while females average 96 inches (240 cm) and 100130 kg (220290 lb). 28 This population occurs in myanmar, thailand, laos, but has not been recorded in vietnam since 1997. In 2010, the population in Indochina was estimated at about 350 individuals. In southeast Asia, tiger populations have declined in key areas and are threatened by illegal production of tiger bone for use in traditional medicine.
22 According to genetic analysis, it was closely related to the siberian tiger. 35 The population inhabited forests and riverine corridors from Eastern Anatolia, south caucasus and coast of Caspian sea, along the coast of the Aral sea, in Amu-darya and Syr-Darya basins to the southern shore of lake balkhash and into the Altai mountains. 34 It had been recorded in the wild until the early 1970s and is considered extinct since the late 20th century. 36 Siberian tiger (. Altaica ( Temminck, 1844). 21 Also known as the Amur tiger. The siberian tiger has a resume thick coat with pale hues and few dark brown stripes.
30 Recorded body weights of wild individuals indicate that it british is the heaviest subspecies. 31 This population occurs in Bangladesh, bhutan, india, nepal, foremost in alluvial grasslands, subtropical and tropical rainforests, scrub forests, wet and dry deciduous forests and mangrove habitats. It is extinct in pakistan. 1 In 2014, the population in India was estimated at 2,226 mature individuals, in Nepal and 103 in Bhutan. 33 Caspian tiger (. Tigris 26 formerly. Virgata ( Illiger, 1815) 21 The caspian empire tiger was described as having narrow and closely set stripes. 34 The size of its skull did not differ significantly from that of the bengal tiger.
25 In 2017, the cat Classification Task force of the iucn cat Specialist Group revised felid taxonomy and now recognizes the tiger populations in continental Asia. Tigris, and those in the sunda Islands. 26 The following table is based on the classification of the species Panthera tigris provided in Mammal Species of the world. 21 It also reflects the classification used by the cat Classification Task force: Non-insular Asia subspecies Description Image bengal tiger (. Tigris ) (Linnaeus, 1758) 26 21 The bengal tiger's coat colour varies from light yellow to reddish yellow with black stripes. 27 Males attain a total nose-to-tail length of 270 to 310 cm (110 to 120 in) and weigh between 180 to 258 kg (397 to 569 lb while females range from 240 to 265 cm (94 to 104 in) and 100 to 160 kg (220 to 350 lb). 28 29 In northern India and Nepal, the average is larger; males weigh up to 235 kilograms (518 lb while females average 140 kilograms (310 lb).

Sondaica in the Greater Sunda Islands and possibly in Sundaland. 22 Results of craniological analysis of 111 tiger skulls from business 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 sumatran and javan tiger as distinct species,. Sondaica with Bali tiger as subspecies. 23 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 write authors proposed recognition of only two subspecies, namely. Tigris comprising the bengal, malayan, Indochinese, south Chinese, siberian and Caspian tiger populations, and. Sondaica comprising the javan, bali and Sumatran tiger populations. The authors also noted that this reclassification will affect tiger conservation management. 24 One conservation specialist welcomed this proposal as it would make captive breeding programmes and future rewilding of zoo-born tigers easier. One geneticist was sceptical of this study and maintained that the currently recognised nine subspecies can be distinguished genetically.
Citation needed The wanhsien, ngandong, trinil and Japanese tigers became extinct in prehistoric times. 17 Tigers first reached India and northern Asia in the late Pleistocene, reaching eastern Beringia, japan, and sakhalin. Some fossil skulls are morphologically distinct from lion skulls, which could indicate tiger presence in Alaska during the last glacial period, about 100,000 years ago. 18 Fossils found in Japan indicate the local tigers were smaller than the mainland forms, possibly due to insular dwarfism. 19 The tiger's full genome sequence was published in 2013.
It was found to have similar repeat composition than other cat genomes and an appreciably conserved synteny. 20 Recent subspecies Following Linnaeus's first descriptions of the species, several tiger specimens were described and proposed as subspecies. 21 The validity of several tiger subspecies was questioned in 1999. Most putative subspecies described in the 19th and 20th centuries were distinguished on basis of fur length and coloration, striping patterns and body size, hence characteristics that vary widely within populations. Morphologically, tigers from different regions vary little, and gene flow between populations in those regions is considered to have been possible during the Pleistocene. Therefore, it was proposed to recognize only two tiger subspecies as valid, namely. Tigris in mainland Asia, and.

This species lived at the beginning of the Pleistocene, about 2 million years ago, and is considered to be a sister taxon of the modern tiger. It was about the size of a jaguar and probably had a different coat pattern. Despite being considered more " primitive the longdan tiger was functionally and possibly ecologically similar to the modern tiger. As it lived in northwestern China, that may have been where the tiger lineage originated. Tigers grew in size, possibly in response to adaptive slogan radiations of prey species like deer and bovids, which may have occurred in southeast Asia during the early Pleistocene. 16 The earliest fossils of true tigers are between.6 and.8 million years old and were found in java. Distinct fossils are known from the early and middle the Pleistocene deposits in China and Sumatra. The Trinil tiger ( Panthera tigris trinilensis ) lived about.2 million years ago and is known from fossils found at Trinil in java.
8 The middle English tigre and the parrot Old English tigras (a plural word) were both used for the animal. 9 These derive from the Old French tigre, itself a derivative of the latin word tigris. The original source may have been the persian tigra meaning pointed or sharp and the avestan tigrhi meaning an arrow, perhaps referring to the speed with which a tiger launches itself at its prey. 10 Taxonomy and genetics In 1758, carl Linnaeus described the tiger in his work systema naturae and gave it the scientific name felis tigris. 3 In 1929, the British taxonomist Reginald Innes Pocock subordinated the species under the genus Panthera using the scientific name panthera tigris. 11 12 evolution Tiger phylogenetic relationships Restoration of Panthera zdanskyi, an extinct relative whose oldest remains were found in northwest China, suggesting the origins of the tiger lineage The tiger's closest living relatives were previously thought to be the panthera species lion, leopard and jaguar. Results of genetic analysis indicate that about.88 million years ago, the tiger and the snow leopard diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. 13 14 Results of a phylogeographic study indicate that all living tigers had a common ancestor 72,000108,000 years ago. 15 Fossil remains of the longdan tiger were found in the gansu province of northwestern China.
tigers live on the Indian. 1 In 2016, an estimate of a global wild tiger population of approximately 3,890 individuals was presented during the Third Asia ministerial Conference on Tiger Conservation. 4 5 The wwf declared that the world's count of wild tigers has risen for the first time in a century. 6 The tiger is among the most recognisable and popular of the world's charismatic megafauna. It featured prominently in ancient mythology and folklore, and continues to be depicted in modern films and literature, appearing on many flags, coats of arms, and as mascots for sporting teams. The tiger is the national animal of Bangladesh, india, malaysia and south Korea. Contents Etymology The word Panthera is probably of Oriental origin and retraceable to the Ancient Greek word panther, the latin word panthera, the Old French word pantère, most likely meaning "the yellowish animal or from pandarah meaning whitish-yellow. The derivation from Greek pan- all and ther beast may be folk etymology. 7 The word specific name tigris derives from the Classical Greek language τίγρις meaning "tiger" as well as the river Tigris.
Tiger populations once ranged widely across. Asia, from the, black sea in the west, to the, indian Ocean in the south, and from. Kolyma to, sumatra in the east. Over the past 100 years, the species has lost 93 garden of its historic range, and has been extirpated from. Western and Central Asia, from the islands of java and Bali, and from large areas of southeast, south, and East Asia. Today, it ranges from the siberian taiga to open grasslands and tropical mangrove swamps, and has been classified as endangered in the iucn red List. Major reasons for population decline include habitat destruction, habitat fragmentation and poaching. The extent of area inhabited by tigers is estimated at less than 1,184,911 km2 (457,497 sq mi a 41 decline from the area estimated in the mid-1990s.

For other uses, see. Tiger (disambiguation) and, tigress (disambiguation). The tiger panthera tigris ) is the largest cat species, most recognizable for its pattern of dark vertical stripes on reddish-orange fur with a lighter underside. The species is classified in the genus. Panthera with the lion, leopard, jaguar, and snow leopard. It is an apex predator, primarily preying on ungulates such as deer and bovids. It is territorial and generally a solitary but social predator, often requiring large contiguous areas of habitat that support its prey requirements. This, coupled with the fact that it is indigenous to some of the more points densely populated places on Earth, has caused significant conflicts with humans.
