Crocodile Miscalculated It's Chances Against An Elephant 

Crocodiles Versus Elephants.
Such fights most probably can take place when the Elephants go to drink water in the river and one of the Crocodiles tries to grab the trunk or leg of an Elephant by its mouth. In such a situation, due to its impressive power, the Elephant will be able to toss around the Crocodile, and due to the injuries got from the Elephant’s tusks and its feet the Crocodile would obviously let go.
The Elephant is also capable of crushing the skull of the Crocodile with only one kick. Most animals while drinking water, have fallen victims of the Crocodile’s bite and have been killed in that manner. But as it is always in the animal kingdom it’s the survival of the fittest (and often biggest).
