30. Tiger

Although lions are known as the king of the beasts, tigers are also a solid contender to the crown. They’re larger on average, just as deadly, and their dwindling habitat again puts them into conflict with people. The Guinness World Records lists one Bengal tigress known as the Champawat Tiger as the deadliest of the species. This one animal was apparently responsible for approximately 436 fatalities before it was brought down in 1907.
