The Great White, as formidable as it is, would stand no chance against an adult Killer Whale. In the only filmed instance of this in 1997 the Killer Whale killed an albeit smallish Great White very easily. Moreover the Bull shark does cause more deaths than any other shark by virtue of the fact that it can operate in both fresh and salt water.

Hello my name is Gem,

I would have to agree with Anil on the bull shark factor.

The White Shark is mostly feared for it's huge teeth and shear size than because of it's reputation.

The bull shark is much more of a threat than Great Whites do to the bull shark being able to go in both fresh and salt waters.

the bull shark is also known for more attacks on humans than Great whites.

Respectfully,

Gem

Killer whales attack and kill even the largest whale, the blue. They even hunt and kill sperm whales. Killer whale sounds have been played to Great Whites and they bolted like balls from a canon. No doubt, Killer whales are top dog. Great Whites loose.

To add to the Orca's supremacy over the Great White of any other mammal or fish in the vast oceans,the Orcas are not a solitairy mammal,they hunt in packs as you probably already know. Thus making the Orcas a very diversed and complete predatory species. If there were magalodon did exist and Orcas were to hypothetically take on a megalodon.It would be a slaughter for the megalodon.A pod of Orcas would out smart and ultimately kill the massive magalodon.

hi anil i would just like to say in the case of a great white shark vs a killer whale i appreciate the weight and intellegence advantage the killer whale has over the great white but the fight could very easily go either way. The orca has large blunt teeth designed for grabbing and crushing but the great white shark has razor sharp teeth which can cause horrendous damage.I beleive if the killer whale got the sharks head in its mouth he could crush the skull of the shark and the fight would be over but the great white is faster than the killer whale and if the shark swiveled underneath the whale he could inflict a killer bite to the underbelly of the killer whale .. best regards steve.

In regard to your answer concerning the outcome of a Great White versus Killer Whale battle, all known verifiable evidence supports the Killer Whale as the winner in almost all circumstances. In her book, The Devil's Teeth Susan Casey details the several weeks she spent on the Farallone Islands with Great White Shark researchers Peter Pyle and Scot Anderson. Pyle and Anderson have studied the predatory habits of great white sharks for over 15 years with the Farallone White Shark Project. A documentary on their work was released by the BBC and titled the Great White Shark. I own it and it's superb. They report that when the Killer Whales show up at the Farallones and kill one of the great white sharks, all of the other white sharks leave the area at high speed. How the Great Whites know when the killer whales make a kill is unknown. They also report that Killer Whales actively hunt great whites and they know exactly how to capture and kill them. On page 184 of the hard cover edition of The Devil's Teeth they report that on 10/4/1997 two maurauding Orcas (Killer Whales) attacked and killed a white shark by flipping the shark on its back and holding it until it drowned. Then they ate him in front of a boatload of tourists. Immediately after the kill all of the great white sharks at the Farallones vanished. It happened again on 11/19/2000. But this time many of the white sharks were tagged with satellite tracking devices. Immediately after the attack the great whites left the islands for several days until the Orcas left. When push comes to shove, it seems that, at least in these instances, it's no contest; brains, blubber and size over the mean teeth machine.

Also, Orca families inherit eating habits from their own pods that they grown up with and learn from. There is no argument that the Orca is the TOP predator of any sea. This would interesting if the ca2 offspring also hunted white Sharks like it's mother.

Actually Killer Whales do kill and eat Great White Sharks. This is not opinion but fact. There are several verified incidences of orcas killing great Whites.

I have the answer for you sir. A fully grown great white at approximatley 18-20+ feet (females being the larger and stronger variety) against a fully grown killer whale (20-30 feet, and 1-5 tons heavier than the white shark) making a confrontation will have many various results. A white shark can stay underwater indeterminably, a whale must surface, however, the Orca is a warm blooded mammal, and is heavier than the white shark. Some orca have been spotted and observed, one in particular, over the course of an entire week, would gain new large bite marks on it, every day, and did not end up dead until 9 days later. There were infact white shark teeth found in these bites, it is still not known if the shark did all of the attacking, or scavanged, however new bites were found as those 9 days went by. The size and width of these bites suggested that had it been a white shark, it would have been a massive shark, between 18-22 feet long. However, this is undetermined and unproven to be a dead orca as the result of a white shark, later this scenario was put into play in hollywood on the film Jaws.  The only documented conflict  between the two involved a 9.5 foot juvenile white shark (about as big as a fully grown zambizi/bull shark) and an orca, in which the orca easily killed and ate with its baby, the white shark. Had it been a fully grown mature female white shark, scientists believe the orca might have still prevailed, but they concluded that the orca would have avoided the white shark is a more likely scenario. The white shark is more of a seal killing machine, it has been documented ripping apart fully grown elephant seals off the coast of oregon many times, these seals are massive and show just how deadly the white shark can be.



White sharks do not injure or kill as many people as zambizi/bull sharks, bull/zambizi sharks thrive near coastal waters such as beaches, and have even been known to swim up rivers and thrive in fresh water. The movie JAWS was based on a series of bullshark attacks off the east coast of the united states, however for theatrical and hollywood purposes, they made it one giant white shark.



The Megaladon is the ancestor of the present day carcharidon carcharius (Great White Shark) many fossils have been recovered, during the time of the megalodon the earth had much more oxygen in its atmosphere and gave rise to huge animals like dinosaurs and large oceanic creatures like the megalodon. Over time these megalodon fossiles have taken slight changes and grown smaller and sleeker, giving us what we have presently, as the Great White .



Final Conclusion - Orca will hunt in packs, and have been known to kill and eat grey whales, sperm whales, and humpback whales.    Great whites will usually hunt alone, however once the blood is in the water, more will generally show up and they will inadvertently help eachother kill many prey. But never has a white shark been documented killing a healthy adult whale with the exception of dolphins and one possible case of several great whites herding a school of 30 foot whales into a beach, the whales were found dead and on the beech, hundreds of them, with massive great white shark bites in almost all of them. This is very controversial, but the end result will warrant in favor of an Orca. In addition, there is conclusive evidence of megalodon (picture a 40-60 foot long great white) having feasted on whales almost identical to the present day orca. However these megalodon have evolved over the years to be reliant on seals and slightly less oxygen therefore their size has decreased to 18-23 feet in legnth.

NO don`t you know megalodon is bigger than the blue whale? the true length of it is more than 145 foot monster it is like 5 biggest monster truck everything in it`s path will be eatwn if they do not exist this will be sure they will eat all the humanity. even mixed power with great white shark,killer whale or everything megalodon is the winner

They would try to avoid each other, Killer Whales don't hunt for them. If there were to meet, then a Killer Whale would/could easily kill a Great White. After all its a mammal v a fish. Everything is in its advantage, size, hunting in pods, intelligence, like a heavyweight V a lightweight. However, The Great White, could and is more then capable of killing an Orca. A smaller Orca, lost from its pod, an injured Orca would be killed though the Great White would most likely just swim by. The Great White is the Oceans top predator, was perfectly built in that sense. While Killers get desperate and are coming into shallow waters for food and end up beached. As an hunter as a predator, the worlds No1 is a Great White Shark, examine how its built, how sophisticated it really is. Sure the Killer Whale would kill one, of these but its very rare and not a common occurrence. But I'm also sure a Great White, has killed an Orca just hasn't been reported. But 999/1000 they avoid one and other, why? Because they are both smart enough to not put themselves at risk and have a great respect for one and other. Like we should do. People must remember to talk about a FISH, in comparisons to a mammal, testifies how Great The White really is.

This is probably old but in my answer and research I ve seen that the Killer whale or (Orca) will in fact win between the two.It is also a fact that Orca hunt Great whit sharks they eat their liver.So in saying that A great white does not stand a chance against a Killer whale
