Through the lens, I saw it was a crocodile that had been dragged out of the water by a waterbuck, away from where I assumed it was caught, and that the crocodile was trying to pull the buck back into the water.
As the waterbuck tired, the croc managed to pull it back to the water’s edge, where the buck lay still for a while. After a short breather, the waterbuck then made a break for it when the croc changed its grip. The buck managed to hobble away but had a broken front leg.
