Wolf attacks are very common in the areas where wolves reside. Over the period of two decades, the average fatality rate from wolves is near to 10.

13: Lions – over 22 deaths a year

Lions are also one of the most deadly creatures. Back in 2005, a study showed in Tanzania alone, 563 people were killed because of lions. The average rates goes up to over 22 per year.

12: Elephants – 500 deaths year

Though elephants are considered friendly animals, they are also a cause of death for numerous people. A study from 2014 stated 391 deaths from elephants in India alone, the worldwide average was 500 deaths per year.

7: Tsetse flies – 10,000 deaths a year

These flies pass on a disease known as sleeping sickness that initially starts with headaches, joint pain, itchiness, fever, later proceeds so serious neurological problems and eventually resulting in death. However, fortunately the number of deaths by these flies is declining.

These snails carry parasitic worms that infect people with a disease ‘schistosomiasis’ that causes abdominal pain and blood in urine or stool.

4: Dogs – 35,000 deaths a year (Gasp!)

Rabies infected dogs can turn out to be one of the deadliest animals; though can be prevented through vaccines, yet it leads to 35,000 deaths annually according to World Health Organization (WHO).
