From The Daily Mail:
With the 40th anniversary of JAWS rapidly approaching, and shark attacks making the headlines, you may be forgiven for thinking that they are the most deadly animals in the world.
But despite being the ultimate killing machines, sharks are only responsible for on average one death a year. In fact, you should be far more afraid of bees, who kill almost 60 people a year, or even cows, which are responsible for around 20 deaths.
According to other sources, mosquitoes cause the most deaths, but hey.
