A saltwater/estuarine crocodile at a local Wildlife Park. We only have two crocodile species in northern Australia: The Saltwater and the Freshwater crocodiles. The freshies, as they're commonly known, are generally safe to swim near as they tend to steer clear of humans and are not capable of doing any serious harm to humans. The salties, on the other hand, are distinguishable by their wider mouths and larger overall size, are more similar to the Alligator, and are known to attack/consume much larger prey, such as buffalo, cattle, and the occasional human being.
