Typically attacking in the night using sharp claws to inflict deep wounds and with a bite that can crack bones and your skull, the lion is a fearsome beast
Hippos use those long (up to half a metre) sharp canines for fighting and just one bite from the creature can cut a human body in half. Ouch. A hippopotamus bite comes with a force of 1,800 psi, nearly three times that of a lion.
The crocodile is a famously ferocious animal that causes up to 1,000 reported fatalities a year. Just one look at those teeth should tell you why these reptiles are so dangerous.
These ancient and aggressive creepy crawlies sting with their tail and inject venom into their prey. With over 2,600 species of the arachnid, only around 25 carry a powerful enough toxin to kill humans.
Mosquitoes are the most dangerous animal in the world, killing 725,000 humans per year through spreading diseases such as malaria. Only female mosquitos bite, making them the most dangerous.
