In this rather grainy video, we see how a crocodile latches onto a Cape Buffalo's hind leg in an attempt to make a meal of it. It's dragged out of the water by its intended prey . . . then another buffalo intervenes.
I bet that crocodile didn't survive for long. Even if it made it back to the water, other crocs would be attracted to the scent of blood from its injuries. It doubtless ended up as food for its fellow critters.
