I would have to agree with the hippo and the elephant as well for the most dangerous. The only one shot kill Ive seen on the elephants (on hunting show) were perfect headshots from10 - 20 yds out. Ive never seena show when they were hunting hippos but i too have heard about them killing more people then any other animal in that country. But due to there size Id imagine it would be just like killing the elephant exceptfor the fact that they are more aggressiveand it could be more of a challenge getting close without getting charged.I think I would be hesitant to try and takeone of the above with either a spear or bow.
