Video: While on safari in northeastern South Africa, a retired couple witnessed a harrowing scene involving a crocodile and a rather unfortunate wildebeest. But just when things appeared most grim for the reptile's next meal, something completely unexpected happened.
This remarkable scene was captured by 72-year-old retiree Mervyn Van Wyk and his wife Tokkie while visiting Kruger National Park, one of Africa's largest game reserves. As the couple approached a dam, they noticed several wildebeest, zebras and impalas grazing on the opposite side, so they turned the car into a position such that Ms Van Wyk had a clear view to take some photos.
"We happened to notice that one unlucky wildebeest was grabbed by a crocodile on his right rear hoof. This began a game of tug of war that lasted for around eight minutes," writes Van Wyk at the Kruger Sightings YouTube page. "The wildebeest would try dragging itself out of the water whilst the croc would pull it back in. You could see the exhaustion that the poor wildebeest was experiencing. Tokkie kept the cam rolling while I observed the area in the close vicinity. I then noted what I thought were more crocodiles approaching but then saw it was actually two hippos."
As the video shows, the hippos slowly approached the scene and then, incredibly, sprang onto the crocodile, forcing it to release its death grip on the wildebeest. The prey animal took advantage of the situation and escaped -- though it appears to have a very badly broken hoof. Sadly, this animal will likely not survive.
"We could not believe the rarity of this situation," said Mervyn. "I have never seen a hippo coming to the aid of another animal, it was simply astonishing."
An obvious question to ask about this episode is why a pair of hippos would even care about the member of another species. Evolutionary biologists have a hard time explaining altruism and empathy among members of the same species (what's referred to as kin selection) let alone members of completely different species, as is the case here. In this instance, however, altruism likely has nothing to do with it. Hippos are territorial animals, and they don't like sharing their turf. Ironically, the hippos probably perceived the wildebeest as an intruder, and this "rescue" attempt might have been an effort to shoo the struggling mammal away.
