The following are more interesting and unusual tiger facts:
• The lion is the closest relative to the tiger. Without their fur, they would be hard to tell apart.
• Most tigers have over 100 stripes and no two tigers have the identical pattern (like fingerprints).
• Tigers, like house cats, can protect their retractable claws by pulling them into a protective sheath to keep them sharp.
• A tiger's roar can be heard over a mile away.
• Tigers can live up to 15 years in the wild and up to 20 years in captivity.
• In the early 1900s, there were roughly 100,000 tigers. Today, fewer than 5,000 remain. Loss of habitat, loss of prey, and poaching are mainly responsible for their decrease in numbers.
