Crocodile eats younger croc in South Africa

Humans turning into cannibals may seem like the perfect script for an apocalyptic film.

But crocodiles don’t have to wait for the end of the world before a bigger croc comes along looking for an easy lunch.

This is exactly what happened to one 100kg crocodile who had the misfortune of coming up against a 900kg beast.

The reality of the ‘croc eat croc’ world was captured at Sunset Dam in Kruger National Park.

However, South Africa’s biggest game reserve will now be one crocodile short.

As shocking as this cannibalism seems, it is not an uncommon act for the reptile species.

Crocodiles are known for turning on each other to control their population.

It often happens when they run out of animals to hunt and eat, or they may do it just to show dominance.
