I'd just like to point out that if I was allowed to vote on myself, the elk would be the obvious choice.
The giant elk, the king of the wide forests in northern Sweden, can weigh more than a ton, and several people are killed by them each year. Even a half grown elk would beat the crap out of all the other wimpish creatures in the list.
A Kiwi..? Bah! The elk wouldn't even notice stepping on one...
