Killing more people every year than sharks, crocodiles, and stonefish combined, this box of death has been labeled “world’s most venomous animal.” Its venom is so potent in fact, that in some cases treatment consists of little more than last minute CPR.

While humans are generally not on their hit-list, some lions have been known to actively seek out human prey. One famous case was that of the Tsavo man-eaters in 1898 who mauled and killed 28 railway workers in Kenya over a 9 month period.
