Sorry about the title - couldn't think of anything more inspirational. This healthy youngster was shot (photographically) in the Australian Reptile Park near Sydney. One of the keepers gave an interesting demonstration on how to differentiate between 'crocs' and 'gators'. He brought out two 3ft specimens and set them down on the ground. He then nudged the alligator on the rear leg. The alligator just waddled off to find somewhere less bothersome. The crocodile, on the other hand, tried to take his leg off! Crocodiles can run but it's their lateral speed and reaction that makes them so deadly.
Can I add that this is not recomended as a way to tell the difference.
