To most people, alligators and crocodiles look similar. While they do share many of the same features, they couldn’t be any more different to a trained professional. Typically, crocodiles are more aggressive than alligators, which makes crocodiles more dangerous than alligators. Alligators are opportunistic feeders. They do not hunt unless it is necessary. However, that certainly doesn’t mean that you should swim with them. Caution should be exercised at all times near alligators and crocodiles.
