We don't know what ticks animals off to a violent tune, but it's always safer to be cautious when approaching them. Especially if you are driving a car up to it in a South African safari park.
A British schoolteacher and her fiancé were driving through the Kruger National park, when they stumbled across an elephant strolling along the unpaved road. They somehow angered the animal which turned around and in a mere seconds turned the VW Polo they were in, into scrap.
One of the elephant's tusks apparently wounded the male occupant, but it was the elephant which was not so lucky. The reason? It was later tracked down and killed, with park rangers explaining that the male specimen was looking to reproduce and there its testosterone levels were high, hence the violent behavior.
That's pretty sad. It really isn't the elephant's fault. After all, we are kind of occupying their space.
