Panthera tigris altaica
The Amur or Siberian tiger (Panthera tigris altaica) is a subspecies of tiger characteristic of evergreen forests of the southeastern tip of Russia, in the region of the Amur River and the border between Russia and China. Traditionally it is considered the largest subspecies of tiger and the largest feline in the world naturally raised.
|Subspecies:||P. t. altaica|
The Amur tiger is about 107-110 cm tall at the shoulder, about 6 cm higher than the average Bengal tiger. Adult males measure 190-230 cm. length (head and trunk) plus a tail of 90-100 cm. The largest male of which was reliable references have a copy of 335 cm. total length measured in a straight line (350 cm. on the curves of the spine), shot in the Sungari river bottom, Manchuria, in 1943. Females reach a total length of 240-275 cm. and weighing 100-167 kg. Baikov weights established that "normal" for males and females of this subspecies is 320 kg and 180 kg respectively, have even been reported cases of large males that reached 390 -- 400 kg. However, according to Dr. Vratislav Mazák, there was no scientific verification in the field, so can not verify the veracity of these reports. An unconfirmed report tells of a male tiger hunted in the mountains Sikhote-Alin in 1950, who weighed 384.8 kg., it was estimated that likely would have a total length of 349 cm., but the latter figure is hypothetical. According to Guinness World Records, more captive tigers Heavy was a male called "Jaipur", which measured 333 cm. total length and weighed 465 kg., at the end of his life in 1999.
The Siberian Tiger Project (Siberian Tiger Project), which has operated in the Sikhote Alin reserve since 1992, has found that 206 kg. seems the more weight that have been verified, although based on a limited number of specimens. Dale Miquelle, director of the program, says that despite the repeated assertions in the popular literature that the Amur tiger is the largest of the species, their measurements taken more than fifty captured individuals suggest that body size is similar to Indian tigers. A recent study calculated an average weight based on historical examples of 215.3 kg. (474.7 lbs.) For males and 137.5 kg. (303.1 lbs.) For females. However, based on current examples, the calculated average weight of 176.4 kg. (388.9 lbs.) For males and 117.9 kg. (259.9 lbs.) For females.
These weights are lower than those calculated for the specimens that inhabit the Indian subcontinent, so these data suggest that at present, the Bengal Tiger subspecies (Panthera tigris tigris) reaches a larger size. The morphological measurements taken by scientists of the Siberian Tiger Project in Sikhote Alin, state that the average head-body length, measured in a straight line is 195 cm. (range 178-208) for males and 174 cm. (range 167-182) for females. The tail is on average about 99 cm. in males and 91 cm. in females. The longest male ( "Maurice") measured 309 cm. in total length (tail 101 cm.) and had a chest circumference of 127 cm.). The longest female ( "Maria Ivanovna") measured 270 cm. in total length (tail 88 cm.) and had a chest circumference of 108 cm. These measures show that the current Amur tiger is longer than the Bengal tiger and African lion.
In the cold months the hair becomes longer and thicker, growing to 105 mm in length in some areas in order to protect the freezing winter.
