The most dangerous animal in the world is not a shark, neither a human being. We decided to classify the most dangerous animals in the world. Most deaths occur in the world due to the attack of animals rather than any transmitting disease. Yes, you read, right! There were about 438,000 deaths in 2013 because of homicides. No doubt, humans are the most dangerous animal and the deadliest mammal to humans. But we excluded humans from our list because we are not quite our own worst enemy, but yes we’re pretty close.

Note those ranking animals according to their deadly behavior is difficult, so these are mostly rough estimates. The list is representative of different types of dangerous animals in the world.
