Tigers are the biggest wild cats, weighing up to 363 kg (800 lbs) and measuring up to 3.3 m (10.8 ft) long.
Each tiger has a unique pattern of stripes, much like human fingerprints.
Tigers hunt alone, primarily at night, using stealth to stalk their prey.
Unlike most cats, tigers enjoy water and are strong swimmers, often cooling off in pools.
A tiger's roar can be heard up to 3 km (1.9 miles) away.
Tigers have existed for about 2 million years.
They can survive on just one meal a week, but they hunt daily
