Even though it is a herbivore, the hippo is renowned for being extremely aggressive. In the video filmed in 2001, Steve explained his wish to avoid the animal. “I ran into some really angry hippos,” he said. “In some countries of Africa, hippos are known to cause more human fatalities than any other species, even more so than Nile crocodiles. And by crikey, they get grumpy. They pushed me right out of the river.”
Irwin continued, “They’ve got huge great tusks, and when they get angry, they charge straight at ya. I was quite fearful and respectful of them, so I went around ’em. I left my canoe in the end.” The footage shows Irwin as he observes a hippo herd from afar, only to attract the aggression of the bull.
