Who would win in a fight, a lion or a tiger? Well, if size has anything to do with the matter, the tiger would win. That's because tigers are the largest of all cat species. They grow up to eleven feet long and weigh as much as 670 lbs. This makes tigers the third largest land carnivore. The only larger land carnivores are polar bears and brown bears. Tigers are not only large, they are also fast. They can sprint as fast as 40 miles per hour for short distances and leap as far as 30 feet horizontally. This makes for an extremely dangerous pounce. You might not think that such large, fast, and ferocious creatures need help to survive, but they do. The tiger is an endangered species.
