This isn't the first time we've featured brutal animal attacks on this list, and it won't be the last. Forget all those cuddly-wuddly cat photos that clog up Instagram, because wild animals - especially in their natural habitat - are not afraid to strike back. Either they hate smart phones or they think they look fat in this fur, because they especially seem to nuts when there's a camera around.
Bears in North America are probably the most dangerous of all. Most of the time, they really are only being defensive. But a camera flash to them is like paparazzi to celebrities - they get instantly enraged. Like this bear, snapped by a hiker in New Jersey. In a terrible twist, the bear pounced on the 22-year-old walker just moments later and killed him instantly.
