Yes, tigers and crocodiles do not make good bedfellows. They are enemies of each other in real life. But this has been created by human beings only; nature wants every creature to survive on the earth, but we humans indulge in activities that cause harm and worry for our fellow creatures around us. We hunt them, eat their meat, capture them, and force them to entertain us in circus shows. We even kill them on roads while they cross for mating or hunting purposes.
