Crocodiles (subfamily Crocodylinae) or true crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodylinae, all of whose members are considered true crocodiles, is classified as a biological subfamily. A broader sense of the term crocodile, Crocodylidae that includes Tomistoma, is not used in this article. The term crocodile here applies only to the species within the subfamily of Crocodylinae.
To begin with, Crocodiles are from the crocodilian family and the alligatoridae family belongs to the alligators. If you look at the snout on the crocodiles, you will see it looks like a narrow âVâ that is very long, while the alligatorâs snout has a wider âUâ-shape.t is not uncommon for people to mistake a crocodile for an alligator. Yet once you learn a bit about them it doesnât take long to realize that there are several differences between the two. Although they look very similar to each other once you know the differences between the two, itâs not hard to tell them apart.
