If you shave the hair off a tiger, it will look exactly like a shaved lion; the stripes are only on its fur, not on its skin.

The further north you go the larger the tigers get; Siberians are the largest tigers. Sumatrans are the smallest.

Tigers generally prefer large, wild prey. Some favorites: pigs, deer, antelope, buffalo, and wild cattle called gaur. Some tigers even attack elephants. Tigers also snack on smaller animals such as monkeys, birds, frogs, even porcupines.

The tiger drags its kill which may outweigh it by hundreds of pounds to a favorable feeding spot near water.

Patiently, without a sound, the tiger watches, stalks, and attacks. A tiger can take 30-foot (9-meter) leaps to bring down its prey, which it asphyxiates by holding the animal down and biting its neck.

Guarding, feasting, napping, the tiger stays for days, leaving nothing but the animal's bones and stomach.

Tigers rarely live more than 15 years in the wild. In captivity, due to improved diet, veterinary care and the absence of numerous other threats, their life span can extend to more than 20 years.

Tigers are diurnal, with peak periods of activity at dawn and dusk.

No tigers purr. In fact, purring is one of the attributes used to separate the so-called "small" species of cat from those known as "large".
