Which would win shark or croc?

Depends on the shark. A great white shark attacks from bellow and since crocodiles have soft stomachs they would most likely lose. Great whites also have electrical sensors on their nose and a very good smell which would give it the upper hand,even salt-water crocodiles would be crushed by one blow to the stomach. But all other sharks would lose to a salt-water crocodile,but this is not always the case with other species of crocodiles and sharks
