You can always tell the creatures that even the crazy pros like Irwin, O'Shea and the others fear viscerally ... they start sweating and their patter becomes stilted and unfocused. With snakes, that always happens when they come accross the mambas, King Cobras, Austrailian brown/fierce snakes and big rock pythons. They're the mankillers.
My pal told me that it is customary for the locals to get a shotgun and just blow away the mambas whenever they are encountered. Nobody wants to mess with them, even though they are generally shy creatures and hustle into hiding at the approach of humans. Puff adders kill more humans, because they are like rattlers without the rattle ... they rely on camoflauge, sit on the ground, and people step on them and get tagged. But its the mambas the locals fear in a primal way.
I've noticed that. You can tell when their on the edge.
