Question: can crocodiles and alligators mate?
Answer: aureus, and yes, they ALL can interbreed, and are fertile. Probably a “superspecies ring”, rather than discrete species. Now, notice that Alligators have their own genus, Alligator, and Crocodiles have their very own, Crocodylus. They are genetically too far apart, even though related, to produce “Crocogators”.
