With all due respect, you have not likely seen a croc have you? That is so obviously a crocodile that it's not any question. Further there is a warthog in it's mouth and there are no warthogs in Florida.
The simple coloration on this Croc is different then an Alligator, and the snout has indentations for the lower teeth to be exposed, Alligators do not have exposed lower teeth, only the uppers are.
I'm simply stunned that this is even in question by people? It's like posting a zebra photo and having people say it's a donkey.
Gators are almost completely black
Croc's colors are much different, compare to the photo above now!
Okay look at the rounded snout of the Alligator with no exposed lower teeth, nor is there a notch in the skull, to expose the lower teeth to make them visible.
Okay, here is the Croc's skull with the exposed lower teeth and the notch in the skull. Look back at the photo above..........any more doubts?
