What animal kills the most humans annually?

Mosquitoes are responsible for more human deaths than any other type of animal. No other animal comes close to the number of deaths caused by mosquitoes.

Mosquitoes are estimated to transmit disease to more than 700 million people annually in Africa, South America, Central America, Mexico, Russia and much of Asia with millions of resulting deaths. At least 2 million people annually die of these diseases.

Humans

Over 5,000,000 people worldwide died every year at the height of the Black Death in 1349 (probably bubonic plague bacterium carried by rat fleas in turn carried by black rats), eventually killing 30% to 60% of all humans in Europe.

20,000 to 94,000 people worldwide die each year from snakebites, according to Kasturiratne et. al.

52,495 people in the US die from influenza (a virus) and pneumonia (most often caused by pneumococcus bacteria) in 2007, according to the CDC.

Humans, We are mammals and animals, are we not? We slaughter other humans everyday, millions die because of us each year, we are obviously the worst animals on the planet.
