  • All five remaining tiger subspecies are endangered.

  • Tigers live alone and aggressively scent-mark large territories to keep their rivals away.

  • Tigers use their distinctive coats as camouflage (no two have exactly the same stripes).

  • A hungry tiger can eat as much as 60 pounds in one night, though they usually eat less.

  • A tiger's roar can be heard as far as 2 miles away.

  • Females give birth to litters of two to six cubs, which they raise with little or no help from the male.

  • Cubs cannot hunt until they are 18 months old and remain with their mothers for two to three years, when they disperse to find their own territory.

  • While able to achieve bursts above 35 miles an hour, the tiger is built for strength, not sustained speed.

  • India is home to some 50 percent of the world's wild tigers.
