Cassowaries

Cassowaries are scary birds. These "murder turkeys" have five-inch claws, may grow to seven feet tall, can run at more than 30 mph, and they wear helmets. They are also among the few species of bird that have killed humans, although that is relatively rare. Still, just because a cause of death is rare, that doesn't mean you tempt fate, yet in this video we see plenty of people getting close to cassowaries. Dr. Ann Jones explains what cassowaries are all about, and why you shouldn't mess with one. You won't win. (via Damn Interesting)
