The deadliest animals ain't the ones you think... not sharp toothed, sharp clawed carnivores. Look to the large domesticated animals--esp. cattle and horses. Their size and human contact with them in farming causes the most human deaths. After that come the bees--especially "africanized" honey bees in the South and Southwest. And then there is man's best friend... dogs account for 4.6 deaths per 10 million people. Of course injury by animals is another matter...with about 1% of all emergency room visits do to household pets.
