Who'd win these croc vs shark matches?

The problem with asking questions like this is you have to set the scene. Are they close to land are they in the ocean? Crocs do need to breathe whereas a shark doesn't. Crocs sometimes drown their prey once they are dragged underwater, sharks just take chunks out of you. As to the species that you choose to match up, hammerhead aren't usually an aggressive shark and it has been doented that the bubbles from a scuba tank can scare them away. The Oceanic white tip is known as one of the four most dangerous to humans, but don't have a mive bulky body. The bull can go into fresh water, I have heard they were found several miles inland in the Nile. The Great White with few exceptions mostly rooms open deep cold water and probably won't encounter a croc. Your link on #7 did work btw. For the crocs, most of them wouldn't venture into the ocean enough with the exception of the saltie to encounter sharks in my opinion. If they did encounter each other and fought, the winner would be the one who got the most bites in and the most damage done. I think the crocs disadvantage of having to breathe air, even if it's a few hours later, would be their downfall.
