Pythons and crocodiles are both large reptiles. Pythons can swallow some smaller crocodiles, but larger crocodiles can't. Because the crocodile is close to the ground, it is difficult for the python to find a good place to wrap it. In addition, crocodiles have a strong bite force and will not let go once they bite. On the whole, the battle between crocodile and python has not yet been won, and the two are tied. We have also summed up some experiences. If a python wants to kill a crocodile, it needs to be more than twice as long as a crocodile. If the body length is equal to or slightly longer than the crocodile, it must be dead; If the body length is between 1.5 and 2 times that of a crocodile, it is a big battle, which may last for a day and a night, or even longer.
