An alligator belongs to the Alligatoride family and a crocodile belongs to the family of Crocodylidae.

Let’s continue in the coming section with the facts and differences between an Alligator and a crocodile!

Difference Between Alligator and Crocodile: How are alligators and crocodiles different?

Crocodiles are aggressive, unpredictable, and far more likely to attack. Alligators would rather escape from an encounter with a human than attack.

If at a glance you will look at the crocodile or an alligator, you may not be able to find the difference as these two have major resemblance in terms of their size, body shapes, and eating habits. Both the cold-blooded species are reptiles and carnivores. So, how to recognize whether the reptile is a crocodile or an alligator. Let’s understand the difference between these two with this quick table listed below:

Similarities between Crocodile and Alligator

The biggest resemblance between these two species is that both are reptiles. Another common point between these two can be their food, both crocodiles and alligators are carnivores, but they do not require food frequently unlike other reptiles or mammals. Crocodiles and alligators both require an outer source of energy to maintain the temperature of their body.

Coming to their attacking tendencies and ghastly nature, a crocodile is more hostile and combative to humans or its other prey as compared to alligators. Alligators are comparatively calm and like to stay in their territories. So, next time you come across a crocodile-like reptile walking away from you (unless you trigger them like by feeding them) you can tell it is an Alligator.
