Bengal Tiger-Panthera tigris tigris
The Bengal tiger (Panthera tigris tigris) is the most numerous tiger subspecies. Its populations have been estimated at 1,706–1,909 in India, 440 in Bangladesh, 163–253 in Nepal and 67–81 in Bhutan. Since 2010, it has been classified as endangered by the IUCN. The total population is estimated at fewer than 2,500 individuals with a decreasing trend, and none of the Tiger Conservation Landscapes within the Bengal tiger's range is large enough to support an effective population size of 250 adult individuals. Bengal is traditionally fixed as the typical locality for the binomial Panthera tigris, to which the British taxonomist Reginald Innes Pocock subordinated the Bengal tiger in 1929 under the trinomial Panthera tigris tigris. It is the national animal of both India and Bangladesh. The Bengal tiger's coat is yellow to light orange, with stripes ranging from dark brown to black; the belly and the interior parts of the limbs are white, and the tail is orange with black rings. Male Bengal tigers have an average total length of 270 to 310 cm (110 to 120 in) including the tail, while females measure 240 to 265 cm (94 to 104 in) on average. The tail is typically 85 to 110 cm (33 to 43 in) long, and on average, tigers are 90 to 110 cm (35 to 43 in) in height at the shoulders. The weight of males ranges from 180 to 260 kg (400 to 570 lb), while that of the females ranges from 100 to 160 kg (220 to 350 lb). The smallest recorded weights for Bengal tigers are from the Bangladesh Sundarbans, where adult females are 75–80 kg (165–176 lb). The white tiger is a recessive mutant of the Bengal tiger, which is reported in the wild from time to time in Assam, Bengal, Bihar and especially from the former State of Rewa. However, it is not to be mistaken as an occurrence of albinism. In fact, there is only one fully authenticated case of a true albino tiger, and none of black tigers, with the possible exception of one dead specimen examined in Chittagong in 1846. Two tigers shot in Kumaon and near Oude at the end of the 19th century allegedly measured more than 12 ft (370 cm). But at the time, sportsmen had not yet adopted a standard system of measurement; some would measure between pegs while others would round the curves. In the beginning of the 20th century, a male Bengal tiger was shot in central India with a head and body length of 221 cm (87 in) between pegs, a chest girth of 150 cm (59 in), a shoulder height of 109 cm (43 in) and a tail length of 81 cm (32 in), which was perhaps bitten off by a rival male. This specimen could not be weighed, but it was calculated to weigh no less than 272 kg (600 lb). A heavy male weighing 570 lb (260 kg) was shot in northern India in the 1930s. However, the heaviest known tiger was a huge male killed in 1967 that weighed 388.7 kg (857 lb) and measured 322 cm (127 in) in total length between pegs, and 338 cm (133 in) over curves. This specimen is on exhibition in the Mammals Hall of the Smithsonian Institution. In 1980 and 1984, scientists captured and tagged two male tigers in Chitwan National Park that weighed more than 270 kg (600 lb).
Megawhaitsia patrichae
Megawhaitsia is an extinct genus of large therapsid, potentially a therocephalian. It lived in the Late Permian in East Russia, and is known only by a maxilla, with a skull estimated to be 40–50 cm.
