    7. Tiger (1,050 psi)

    Of the big cats, tigers have been the deadliest to humans, although this is due mostly to tigers living closely with us in India and other parts of Asia. But it remains true that they are among nature’s finest predators. They are the largest big cat, and with a bite force of around 1,050 psi, they bite almost twice as hard as lions do. Perhaps that’s why lions hunt in packs to take down their prey, while tigers are perfectly content — and efficient — flying solo. No teamwork needed, not with jaws like that. Even a trained tiger who’s “just playing” can do some serious damage. For example, Roy Horn of Seigfried and Roy was the victim of the most famous tiger attack when his show tiger, Montecore, attacked him during a performance. Some experts claim that after Horn tripped accidentally, Montecore was only trying to help by using his maw to grip the entertainer by the throat and drag him off-stage. The tiger’s “assistance” ended Horn’s career and almost claimed his life.
