TIGER, NO LAUGHING JOKE

How is a tiger's face like your thumb?

ANSWER: The stripes on the tiger's face are like your thumbprint. No
two people have exactly the same thumbprint. And no two tigers have exactly
the same stripe pattern.

It takes a lot of muscle to move a 400-pound body (180 kilograms). And
a tiger's body is packed with muscle. So it can leap 10 yards (9 meters)
over level ground, or jump 15 feet (4.5 meters) in the air. Yet it can move
so gracefully that it doesn't make a sound.

Tigers are big-game hunters. They hunt water buffalo, wild pigs, deer,
and other large animals. Water buffalo weigh more than a ton (900
kilograms). It would take 13 men to move such an enormous weight.

Tigers are also big eaters. In a single year, one tiger must eat about
70 deer or other large animals. That is one reason why tigers hunt alone.
If they lived in big groups, they could never find enough prey to feed them
all.

Many people think that a big, dangerous tiger could easily kill all
the prey it wants. But that's not true. In fact, the life of this big game
hunter isn't easy. Most of the animals it tries to attack get away. It
sometimes goes weeks without eating. And then it may hunt animals that can
be dangerous, even for a tiger.

To get enough food, tigers have to hunt day and night. They often hunt
at night, because that's when deer and antelope are most active. Tigers
also hunt at night because they are safe from humans then.

When it hunts, a tiger usually sneaks close to its prey by hiding
behind trees, bushes and rocks.

Tigers cannot run fast for long distances. So they must get close to
their prey before attacking. On their huge, padded feet, they can creep
silently to within 20 feet (6 meters) of another animal without being
heard. Its rear legs press beneath it, like a pair of giant springs about
to be released.

Then, in a series of explosive leaps, it attacks from behind.

Next, the tiger grabs its prey with its claws and pulls it to the
ground. It bites the animal on the throat or on the back of the neck
The tiger has had a long history; the name tiger itself comes from the
Roman word "Tigris", named after the mighty Mesopotamian Tigris River. The
tiger's closest living relative is the lion, and believe it or not, they
can even be interbred. The male tiger can reach sizes of up to 8-10 feet in
length, with three feet for the tail, the male Siberian tiger can reach
lengths of up to 13 feet with weights up to 750 pounds. Tigers can be found
in a fairly diverse area, from north China and Siberia, to the jungles of
Indonesia, even as far west as Iran and the Caucasus Mountains.

The tiger is a solitary animal, hunting mainly at night. The tiger's vision
and sense of smell are relatively poor; the tiger will rely strongly on its
sense of hearing, moving silently through the brush waiting to ambush its
prey. The tiger's main diet consists of deer, antelope, wild pigs, and
cattle. The man-eaters are all too often the sick and injured, too weak to
hunt and capture wild animals. The tiger would much rather flee rather than
stick around and put up a fight.
Tigers are excellent swimmers and will often rest in pools of water
just to escape the heat, or, will swim from island to island such as in the
Sumatran islands. Tigers are poor tree climbers, often only doing so in
emergencies or when they are young, (and on occasion, just out of
curiosity). The Bengal, or, Indian Tiger is the
SIBERIAN TIGER

The largest of all living tigers lives in the coldest climate; but has
thick fur to keep it warm. Its pale color makes it difficult to spot in
the bleak, snowy landscape of Siberia and also makes it easier to get close
to its prey. There are no more than 200 Siberian tigers living in the
wild
