Champawat Tiger
The deadliest man-eating animal in history is the Champawat Tiger. In the late 19th century, one Bengal tiger dragged off and ate 436 people before being taken down by the British hunter Jim Corbett.
Ascaris Roundworm
While this animal might not look as threatening as some of the others on this list, we can assure you that it is dangerous. This little parasite will hatch its eggs inside your intestines, burrow through your guts, and travel in your blood until it reaches your lungs. It’s tiny enough that people don’t even realize they have them most of the time. This parasite is dangerous enough that it kills approximately 4,500 people every year.
