TFS!  I think a crocodile would be capable of killing a GW shark at The same size. Solid armor so that The sharks bite would be less effective and The croc's bite would still be lethal, even though a shark probably could kill a crocodile aswell.

Probably want to start this in the debate thread, but a GWS shark has a far more lethal bite, far sharper teeth and stronger with more weight behind it. It would slice through croc skin just as easy as a hot knife through butter.

Here is a verified predation of a Large croc on a tiny Bull shark
http://www.dailymail.co.uk/news/article-...odile.html

The witness states the amount of struggle the tiny shark was able to put up on the much larger croc and how the croc had to work hard to finally kill the shark. Imagine a 16-20 ft long GWS 4000-6000lbs.
Its just not reasonable that a croc would even attempt on such a large animal let a lone be strong enough to hold on to a animal double its own weight.

Here you see a large croc which was decapatated by a GWS (most likely)
http://www.dailymail.co.uk/news/article-...frica.html

Showing that a GWS would have no problem at all bitting through croc hide. Which would be no surprise as they have far more sharp teeth with a more powerful bite built for slicing.

Was this a Nile crocodile?

I heard that the Nile crocodiles from South Africa are smaller than those live close to the equator.

The Zambezi shark is the same as a bull shark; same shark, different name. They can swim into fresh water. Nile crocodiles are not small crocodiles. But, do Nile crocodiles ever swim into the ocean?

I'm not sure. But I doubt it would matter the type of croc, the shark is going to weigh twice its size, with the most powerful bite in the animal kingdom and teeth already proven to sheer right through croc hide. Thats why when people were doing the animal vs animal debate of croc vs walrus I was picking the walrus. Double the size of the croc but backed with 6+'' of blubber which I think is a better defense compared to leather skin of a croc. Walrus are able to with stand stabs from 2 foot long tusks which I am sure would prove fatal to a croc. But sharks can tear chunks off with ease, so I doubt any skin could with stand a GWS bite.

Ive seen salties swim in open ocean but they seem to stay close to shore. It makes sense since they are cold blooded and energy only lasts so long before they need to bask and gain their strength. Im sure a nile could swim in the ocean, but not sure if they do.

Questions:

Which have the strongest bite, in absolute and relative therms??? Some says the crocodile, some others says the white shark.

Can anyone put data to back up?

Did crocodile skin can protect it from the bite of a big shark? This also apply in the other case too?

Too many statements from both sides, but I only see circumstantial evidence.

Interesting topic. [img]images/smilies/tongue.gif[/img]

Having lived most of my adult life in Florida and south Georgia, I've seen lots of gators. Ever so often an alligator is found in salt water. If an alligator can venture into the ocean, then a fresh water crocodile is likely to do the same from time to time.
http://www.islandpacket.com/2014/07/14/3...walks.html 
 ~One of Hilton Head Island's beaches had an unusual visitor Monday morning: a 12-foot alligator.The big gator -- estimated to be 45 years old and weighing 800 pounds by one of the wranglers called to move it -- walked out of the surf on South Beach near mile marker 10 about 8 a.m. Monday, Shore Beach Service director Mike Wagner said.A bystander notified a member of the beach patrol, who contacted Joe Maffo of Critter Management to remove the alligator, Wagner said.At 9 a.m., Maffo and Critter Management employee Xavier Anderson arrived to find the gator still in the surf, so they looped a rope around its jaw and pulled it out.Maffo said it took 40 minutes to restrain the alligator with ropes, tape and a snare so it could be safely moved. Maffo said he was exhausted after the job and had to sit down on the beach to recover.Read more here: http://www.islandpacket.com/2014/07/14/3...rylink=cpy~"He was a pretty big boy," Maffo said.While Maffo and Anderson tied up the alligator, a crowd formed. Wagner said about 100 people stopped to watch, but Maffo said many more were there, some filming the event.Some onlookers even offered to help Maffo put the alligator in the back of the beach-patrol trailer brought onto the sand to help move the reptile, he said. The trailer was used to carry the gator to Maffo's truck in a nearby parking lot, he said.Maffo said the alligator will be destroyed under S.C. Department of Natural Resources regulations. However, he said he planned to talk to DNR about possibly relocating the large alligator, which he suspected was returning home at the end of mating season.Read more here: http://www.islandpacket.com/2014/07/14/3...rylink=cpy

Bite force
"Bite forceA 2007 study from the University of New South Wales in Sydney, Australia, used CT scans of a shark's skull and computer models to measure the shark's maximum bite force. The study reveals the forces and behaviors its skull is adapted to handle and resolves competing theories about its feeding behavior.[sup][39][/sup] In 2008, a team of scientists led by Stephen Wroe conducted an experiment to determine the great white shark's jaw power and findings indicated that a specimen more than 6.1 m (20 ft) long could exert a bite force of over 18,000 newtons (4,000 lbf)."

But the force wouldn't matter as its the teeth that do the real damage and nothing slices meat better than GWS teeth.

In terms of croc skin, review the images and article on the large croc head that was severed from its body by a large shark and most likely a GWS.
In terms of size, just compare shark weights to croc weights. GWS will be double the size usually. Only makes sense since the largest predators live in the open ocean.

A 5.5 m (18 ft) great white shark would not weigh 4000 lbs and certainly nowhere near 6000 lbs. If a large recorded 6.0 m (19.7 ft) great white weighed 4200 lbs, then using the square cube law, it scales an 18 ft crocodile down to 3204 lbs.

A 6.1 m (20 ft) saltwater crocodile on the other hand, would weigh approximately 2200 lbs.

The crocodile's bite is stronger in relative terms (bite-force), as its jaws have more closing and clamping down force behind them than a shark's jaws. However, the great white has significantly larger and sharper teeth, which results in greater flesh wounds.

Crocodiles have crushing bites. Sharks have slicing bites. They are different, but both lethal.
