There are many factors to consider when determining who would win a fight between a crocodile and an alligator. Size is one factor, with crocodiles typically being larger than alligators. Another factor to consider is the biting power of each animal. Crocodiles have much stronger bites than alligators, which could give them an advantage in a fight. It is difficult to say definitively who would win in a fight between a crocodile and an alligator. However, based on each animal's size and biting power, it is likely that the crocodile would come out victorious.
