Sharks surprisingly don’t like human flesh. The reason why humans are attacked as they are mistaken for being seals or sea turtles (on surfboard). Or sometimes, the shark is taking a test-bite to check-out the flavor of this slow-moving strange creature. Remember all the trash found in the belly of 'Jaws'? Well, it is the tiger shark that is most notoriously known to have such objects in its belly - like an auto license plate. Yeah. Sharks probably like to experiment will new things 😉.

A false killer whale that beached on the Sunshine Coast yesterday bore wounds thought to be from a shark attack, experts have said. The whale died after desperate efforts by up to 50 people who rushed to Twin Waters on a rescue mission. The 3.8 metre female was first spotted at 6:30AM south of Mudjimba Island. Originally thought to be a pilot whale, it was later identified by an attending Australia Zoo rescue team as a “pseudorca crassidens” – a false killer whale.
Workers Attempt to Revive False Killer Whale
The rescue team brought the whale into the shallows to conduct the identification, and efforts then continued to save the distressed mammal, which was believed to be an adult. The injured whale had a damaged dorsal fin and evidence of “superficial” shark bites. The rescue efforts stretched well into the morning as volunteers and veterinarians fought to keep the stranded mammal alive. Australia Zoo veterinarian Tim Portas conferred with Sea World veterinarians during the rescue efforts. A rescue unit spokeswoman said staff and volunteers were able to move the large whale from the beach and transfer it to a truck for transport to the Australian Wildlife Hospital at Beerwah. “Unfortunately, despite everyone’s best efforts, the whale did not survive,” she said. “It underwent a necropsy at Australia Zoo to identify the cause of the stranding. The full cause of the stranding will not be known until the pathology results are completed.” Those involved in the rescue were said to be devastated over the death of the whale. Sources said sightings of the extremely sociable false killer whales are not common on the Coast. They prefer deeper waters away from land."
"Among the 71 false killer whales, 18 individuals (25.4%) showed a total of 20 injuries (66.7% dorsal fin, 27.8% body, 5.6% both dorsal fin and body) . . . . Six individuals (22.2%) had an unidentified injury of which the cause is unknown. These include three individuals that appeared to have crescent-shaped scars on their body which were possibly inflicted by sharks. However, the photographs were of insufficient quality to confirm this. . . . Three false killer whales had injuries that may have been caused by sharks but other causes could not be ruled out. All wounds were located on the dorsal part of the dolphin, which is consistent with other studies [24], [25]. It has been suggested that odontocetes turn their back to the shark when they are attacked or that odontocetes with attacks on their dorsal side are more likely to survive the attack [25]. There are at least ten shark species which are known to predate on cetaceans [25] and six of these occur in the Caribbean, including tiger shark (Galeocerdo cuvier), bull shark (Carcharhinus leucas), sixgill shark (Hexanchus griseus), dusky shark (Carcharhinus obscurus), oceanic white-tipped shark (Carcharhinus longimanus) and mako shark (Isurus oxyrinchus) [63], [64]. It is not known which of these species occur in Aruban waters. In any case, these records indicate that local dolphins may be subject to shark predation."

Quote; "Great white is twice the size." (of tiger shark) which is why I think that saltwater crocodile vs tiger shark makes a better face-off. Surprisingly, off the coast of Australia, the territorial "salty" crocodile chases off large sharks of every species and size. This does not necessarily mean that he can kill them in a fight, but the shark has little to gain from such a struggle.
Reply #43: some good information.

Surprisingly I favour a mako shark over a nile crocodile. To me the mako is the pinnacle species of all sharks. It has one of the largest brain-body size ratios of any shark, has the largest recorded bite force of any fish; 13,000N (3,000lbf) - equal numbers to the nile crocodile & it commonly targets dangerous prey; dolphins, swordfish, seals etc. Also one time a mako shark bit off the back of an orca's tail.
Mako sharks are insanely powerful & I could see one harassing a crocodile from below.

/\ The mako shark is one of my favourite sharks.

Mako bites chunk out of Orca's tail. These predators are not to be messed with.

This is the account that still has me still favoring a Croc at maximum sizes. The question may be did it actually happen this way? A 550 cm (18 ft. GW) lost a fierce battle to a 600cm (19 ft.) Crocodile. Crocodile bit off a sharks head?? That bite force on the Croc is hard to ignore. The estimated bite force on a crocodile is twice that of a Great White. If the Croc gets ahold of the Shark and does the classic death roll then huge gaping wounds IMO would prove fatal to the Shark. There are multiple scenarios that you could possibly build a case for each but I'll stick with the Croc for now. I question the possibilities of a 5.5m gws encountering a 6m saltie - very large individuals. Thus I deem this account untrustworthy.

www.sciencedaily.com/releases/2013/07/130702101506.htm Croc supersense: Multi-sensory organs in crocodylian skin sensitive to touch, heat, cold, environment. The crocodile would not easily be ambushed; even from below. I did read once ( might have been Life Magazine ) that Nile crocodiles keep down the bull shark population ( called "Zambezi shark" in Africa ). The article also stated that in the waters of S.E. America, alligators do the same. But, in these circumstances, the reptile might be preying on smaller sharks - IDK. Reply #3: Great White Shark - 1900 kg = 4,188.78 pounds Saltwater Crocodile - 1360 kg = 2,998.29 pounds So, the shark has a weight advantage of roughly 1,190 pounds ( huge advantage ). If he can hit the crocodile before the crocodile can grab him, yes the shark will win. He hits like a torpedo and takes out a huge chunk of meat. If the croc grabs the shark first, he will then have to go into his death-roll to tear flesh. His teeth are not designed for slicing flesh. If the crocodile grabs the shark at the base of the tail, then the fight is over. The crocodile has enough bite fore to sever the shark's tail. But - is a crocodile smart enough to figure this out? MALTA the 6.75m great white shark (scientifically analysed via pictures - sounds inaccurate but the original measurements given by the capturers was 7.13m, the range also wasn't large - 6.75m is most likely accurate) could have weighed over 2700kg.

tom #19, This is actually not true. Mako sharks - close relative to the Gws - but is much smaller, has a bite force exceeding 3,000lbf. Equal numbers to the Nile crocodile. Just imagine how much pressure a 20+ft Gws could exert.

This is insane undertaker. Thank you. This specimen most definitely surpasses the previous WRH mako. There is no doubt that this shark is more than 445cm. In fact this is probably the single strongest individual shark specimen out of all living species of shark. I say that with confidence. In my opinion this specimen could indeed boss some of the largest great whites such as malta, deep blue, kanga etc. I had heard of this reported size but was sceptical, I was totally unaware that there was a photo.

The saltwater crocodile has two advantages; the strongest jaws of any living animal and superior manoeuvrability.
