1. Every tiger has a completely unique set of stripes. Just like human fingerprints, no two tigers in the world have the exact same stripe pattern! Scientists and researchers use photograph matching software to identify and track individual wild tigers by their unique body stripes.

2. A tiger's stripes are on its skin, not just its fur! If you shaved all the orange and black fur off a tiger, the dark stripe patterns would still be clearly visible right on its bare skin. The hair follicles actually produce dark pigment directly where the dark skin patches are located!

3. Tigers are absolute master swimmers. While most house cats hate getting wet, tigers love the water! They have webbed toes and powerful shoulder muscles that let them swim across wide rivers up to 18 miles long to hunt, cool off, or explore new territories.

4. A tiger's roar can be heard two miles away. A tiger has specialized elastic vocal cords and a thick cartilage structure in its throat that allows it to produce deep, booming roars. Their roars can travel up to 2 miles (3 kilometers) through thick jungle leaves to warn rival big cats to stay away!

5. Tigers have night vision six times better than humans. Behind a tiger's eyes sits a special reflective tissue layer called the tapetum lucidum. It acts like a tiny mirror, reflecting light back through the retina to help tigers see expertly in pitch-black forests while hunting at night.

6. Tigers can leap further than the length of a school bus. Thanks to extremely muscular hind legs, a full-grown tiger can jump up to 30 feet (9 meters) forward in a single bound! They can also spring straight up to 12 feet high into tree branches.

7. Tigers are the largest cat species on Earth. A male Siberian (Amur) tiger can weigh up to 660 pounds (300 kilograms) and grow over 10 feet long from nose to tail! That makes them significantly heavier and longer than wild lions.
