The first recorded white tigers:

The
first white tiger to be captured was not, as is often claimed, the famed
Mohan. There were several captures and a large number of sightings (and
shootings) prior to this. For instance, in one of the earliest records a
white tiger was displayed at Exeter Change in 1820.
Shootings were common between 1892 and 1922 in places like Orissa, Upper
Assam, Bilaspur, Cooch Behar and Poona. Between the 1920s and 1930s fifteen
white tigers were killed in the region of Bihar alone. Some of these
trophies were placed on display in the Calcutta Museum. (Incidentally, this
is the ninth oldest regular museum in the world).
The most famous white tiger of all -- Mohan:
In May 1951, Maharajah Shri Martand Singh was hunting in the jungles of
Bandhavgarh, (central India). On the 25th a report came in that a tigress
had been sighted with four cubs, one of which was white.
The next day a search was carried out designed to find the tigress. This
involved the beating of drums and cans, firing shots, trumpet blasts and
shouting.
Weight: Siberian tigers are the heaviest subspecies at
500 or more pounds (225 kg), with males heavier than females. The lightest
subspecies is the Sumatran; males weigh about 250 pounds (110 kg) and
females around 200 pounds (90 kg).
Measurements:
Depending on the subspecies, the head-body length of a tiger is about 41/2
to 9 feet (1.4-2.8 m). The length of the tail is 3 to 4 feet (90-120 cm).
The foot pads vary in size with age, resulting in inaccurate estimates when
used in censusing wild populations.
Eyes: Tigers have round pupils and yellow irises (except
for the blue eyes of white tigers). Due to a retinal adaptation that
reflects light back to the retina, the night vision of tigers is six times
better than that of humans.
Claws: Like domestic cats, tiger claws are retractable.
Tiger scratches on trees serve as territorial markers.
Stripes: No one knows exactly why tigers are striped, but
scientists think that the stripes act as camouflage, and help tigers hide
from their prey. The Sumatran tiger has the most stripes of all the tiger
subspecies, and the Siberian tiger has the fewest stripes. Tiger stripes are
like human fingerprints; no two tigers have the same pattern of stripes.
Life span: The life span of tigers in the wild is thought to be
about 10 years. Tigers in zoos live twice as long.
Cubs: Tiger cubs are born blind and weigh only about 2 to 3 pounds
(1 kg), depending on the subspecies. They live on milk for 6-8 weeks before
the female begins taking them to kills to feed. Tigers have fully developed
canines by 16 months of age, but they do not begin making their own kills
until about 18 months of age.
Head: Often carries the Chinese mark of wang or king on the
forehead.
