2. Alligator (2,125 psi)
Planning a vacation to Florida, or thinking about retiring there? Keep in mind that you’ll be entering the gator capital of the world. These kings of the Southern American wetlands possess the second strongest bite on Earth, and are faced with no predators of their own. Alligators will eat fish, birds, turtles, and even dogs or the occasional deer. And while they generally aren’t aggressive toward humans, attacks certainly happen. For details, you can see a record of every alligator attack in the state of Florida since 1948, but here are some interesting and disquieting highlights: Alligators killed more Floridians between 2000 and 2007 (12 victims) than the entire '70s, '80s and '90s combined. That number includes three people who were killed within just one week in May 2006. And even if an alligator’s bite doesn’t kill a person, it can still easily amputate a limb, which is what happened to Carol Hough, who lost her arm to a gator in July, and Kaleb Langdale, who suffered the same fate in September.
