Footage of one crocodile brutally attacking another at feeding time in one zoo has gone viral.
A zoo handler is seen throwing a fish into the enclosure, which some of the crocs actually go for.
One does not, and actually attacks a fellow croc, grabbing its leg and viciously twisting it, until it comes off.
The video, taken by one visitor, is thought to have been taken in Australia.
Zoo goers are clearly shocked, and can be heard expressing their disgust at the brutality they are witnessing.
Really though, how shocked can you actually be given Crocs are fairly lethal predators – and it was feeding time after all.
