This eerie clip shows a crocodile dragging a dead buffalo hundreds of meters in a Sri Lankan river The filmer said: "We were doing a boat trip in the Nilwala River in Sri Lanka, when we suddenly saw a buffalo ‘swimming' -- a strange sighting because buffalos don’t swim like this. Afterward we found out it was dragged by a huge crocodile. It dragged the buffalo for a couple of hundred meters to a place where it could eat it. A bizarre thing to look at. And man, what a power."
