Why do people think that alligators are a different species than crocodiles?

They look identical, and they're both big lizards who live in water, so why aren't they just seen as different breeds of the same animals?

    For the same reason clams are different from scallops, wolves from foxes, pythons from boas - different structure as a result of different DNA.

    I used to think that but it was a snap decision.

    It always gives me a smile to read that a person believes their ignorance is some kind of evidence.

    Alligators (of which there is more than one species) and crocodiles (of which there is more than one species) are not the same. They are different. If you are unable to see those differneces that is your problem.

    Alligators and crocodiles are not lizards nor closely related to them.

    The term 'breed' is used with different forms of the same species in domestic animals and not species of wild animal.

    Because they do not interbreed in nature. Different species of crocs may occasionally interbreed, e.g. the Cuban Crocodile and the American Crocodile. But the American alligator and American alligator will not interbreed.  In fact, the alligators and crocodiles are such distant relatives  that they are not only classified as different species, but they are in different genera and families. They last shared a common ancestor way back during the age of dinosaurs some 80 million years ago.

    They're both big lizards? You're just proving your stupidity.

    They aren't even closely related to lizards.  And they don't look identical to each other.

    Actually, they are very different animals. They are in the same order but that is their closest relation.

    If they cannot mate and produce fertile offspring, then they are different species.
