Bull Shark vs. Great White Shark

Great Whites and Bull Sharks are two of the most fearsome fish on earth. These large, powerful hunters are at the top of the food chain, and they know it. But what’s the difference between them? How do you recognize Bull Sharks vs. Great White Sharks? Where do they live? And most importantly, which one’s more dangerous?

Bull Shark vs. Great White Identification

A comparison of how to recognize Bull Sharks vs. Great White Sharks. There is an image of each Shark at the bottom with text above reading: "1. Size: Bulls are much smaller than Great Whites." "2. Color: Bulls are gray-brown with a lighter belly, Great Whites are dark with a sharp change to white underneath." "3. Tail Shape: Bulls have long top tail fins, Great White tail fins are much more even."

The easiest way to tell Bulls and Great Whites apart is by their sheer size. Bull Sharks generally don’t grow longer than 8 feet, and max out around the 11-12’ mark. Great Whites are much, much bigger. They can grow to 20 feet easily, and may hit 25 feet or more, although there are no documented sightings of these monsters. 

That’s fine for adults, but what if you find a small White Shark? The biggest giveaway is their body color. Bull Sharks are light gray or brown on top, fading to a whitish belly. Great Whites have a much more obvious color change. They have a dark gray back that can seem almost black, and the color switches sharply and clearly to white underneath.

Another good way to identify a Bull Shark vs. a Great White is their tail. Bulls have very long top tailfins. Great White tails are pretty symmetrical and not as long compared to the rest of their body. This helps when telling them apart from out of the water: Bulls seem to be all tail with a very fat, stubby body. Great Whites are more evenly-proportioned.

Great White and Bull Shark Habitat

Bull Sharks are often found in very shallow water.

The truth is, you won’t normally need to guess whether you’re looking at a Bull or a White. Why? Because they live in completely different places.

Great White Sharks are the kings of the high seas. They regularly cross entire oceans on the hunt for food. They can sometimes come closer to land, and even show up in the surf (Jaws, anyone?) but you’re much more likely to find them in deep water.

Bull Sharks are the opposite: they’re much more at home in the shallows. Beachfronts and bays are their stomping grounds, and they don’t stop there. Bulls are specially adapted to exploring freshwater. People have found them thousands of miles up the Amazon, and there are even reports of catches in the Mississippi River as far north as Illinois.

Bulls and Whites: Which Is More Dangerous

Along with Tigers, Bulls and Great Whites have racked up the highest reported body count of all Shark species. This has secured them Hollywood stardom, but it’s given them a lot bad press along the way. The question many of you are probably asking is, “Which one’s more dangerous?”

In a straight comparison, Great Whites win hands down. They’re bigger, stronger, faster. Put the two in a fight, and there’s no question which one would win. However, Bull Sharks live much closer to humans. They’re also more aggressive, so the chances of a run-in are higher.

On top of that, scientists believe that many Great White attacks are a case of mistaken identity. They often happened in warm, tropical waters, where Great Whites are uncommon. Chances are, a lot of them were actually Tigers or Bulls. People see a huge Shark swimming their way and the first thing they think is “Great White!”

Here’s the thing, though, Sharks in general just aren’t that dangerous. Sure, they’re apex predators, but the odds of one attacking you are pretty slim. You’re around 75 times more likely to be struck by lightning. In fact, there are probably a dozen things in your home more deadly than Sharks.

Bull Sharks and Great White Sharks are both incredible creatures. They’re fierce hunters, marathon travelers, and a vital part of the ocean’s ecosystems. Hopefully, you now know a little more about what makes them special. If nothing else, you’ve developed a healthy mistrust of everyday household objects.

I’m from Brazil. In the city of Recife we have an extensive record of Bull and Tiger sharks attacks. Thats happens because of the destruction of their hunting grounds to build a harbor, moving them to the beaches where people bath on. On the others hand there are rivers with slaughterhouses on their borders that flows their remains into the same beaches. The animals with few preys, lured by the smell of blood and other animal remains, attacked the people. The Bulls have the reputation of been specially aggressive, attacking in shallow waters repeatedly the same target.

I put the bull shark ahead of the great white for one reason they can live in fresh water which the great white cannot

    Hi Franklin,

    Thanks for reading and for your comment. For fishing purposes, there’s no question, in my mind, that the Bull Shark wins. You can find them more easily, they put up a great fight, and there are so many more of them compared to the Great White – although we shouldn’t take this for granted. When it comes to being dangerous… well, again, the fact that the Bull Shark swims so close to shore probably means they’re more threatening to us, too, although I’d never want to come up against a Great White in the deep!

    Tight lines,

    But u will put bait on a line and catch Sharks for “fun”/ for the great ” fight”? Sharks should be very scared of PEOPLE! If anyone’s ever bitten badly…. there’s almost always a Shark killing spree afterward!
    Of course I would never want to face ANY of them while in the Ocean. I think the Tiger is most dangerous if bitten- bc u won’t get that part back– bc of the teeth are sharply angled backward to hold onto food. Ya, the Bull is most likely the 1 we will run in to…. and they will bite repeatedly if feeding/mad. Great White bites are almost always mistaken identity!! It’d be bad if they had the Bull’s attitude!!
    WE ARE THE #1 PREDATOR- HANDS DOWN!!!

It depends. In a fight between the two and sheer strength and speed the great white is more dangerous.

But to humans it’s just so much more likely that a bull shark would try to attack a human rather than a white shark.

It’s basically a case of one’s more dangerous but the others more likely to actually attack.

    Hi Allen,

    Thank you for your comment. You are right, Great Whites are bigger and stronger, while humans are more likely to come across Bull Sharks since they live much closer to them.

    Have you read our “13 Shark Facts” article? Feel free to check it out – it has even more interesting facts about Sharks.

    Thank you for reading and have a lovely day!

    I’m watching one of the Discovery Channel’s episodes about sharks.. This one is entitled, “Raging Bull Sharks”. Apparently (based upon this documentary) the bull shark’s bite is roughly 300 times per pound more powerful than the much larger great white. For their smaller size, they are extremely powerful. It appears that these ‘bulls’.are as fearless as sharks come. A minute ago, one of these creatures actually attempted to prey upon a herd of hippos wading in an African river. (What other creature would do that)? Eventually, the herd ganged up on the bull shark and he swam away. One helluva of sight. I wouldn’t want to meet up with one in shallow or deep water..

    Hi Griffin,

    Absolutely, Bull Sharks are terrifying! Their bite force and aggression are bad enough, but the fact that they can go into freshwater is the really scary thing!

    All the best!

    EXACTLY!!!! Bull’s are fearless and more adapted to be swimming right by us….
    The Great White uses force from that initial hit, adding those teeth to the 10-20 mph collision… the prey is usually fatally wounded from that ( I know thats not always the style) and usually human bites are accidental or curiousness- even that can be fatal. Tiger shark is the least picky eater!!! I dont want to meet any of them while I’m hanging in the ocean/ river…. they are magnificent creatures— from afar!! 🙂

Some white sharks have brown colored backs rather than dark grey, a good example is the species living in the mediterranean sea.

    Hi Smail,

    Thanks for reading and for your comment. You’re right, some Great Whites can have brown, or even blue or black backs. Yet, the most common color is definitely grey, which helps them camouflage near the seabed!

I noticed that nobody mentions another identifying feature which is the eyes? Great whites are black & bulls have a catlike pupil? Also, don’t they have different hunting techniques? Just want to keep my education current, tx!

    Hi Heather,

    Thanks for reading and for your very good observation and questions. I’ve noticed that Great White Sharks have bigger eyes (proportionally to the side of their heads) than Bulls, but I’d not noticed the different colors! When it comes to hunting, you’re also right. Bulls tend to head-butt their prey before taking a bite, while Great Whites will eat their prey right away. Not only that, but Bulls tend to eat fresh meat, and a range of it, from crustaceans to other Sharks, while Great Whites only go for bigger fish, and will even hunt for floating, dead creatures. This is why they’re more likely to jump out of the water, as they can feed near the watertops. I hope this helps.

    Hi Fatima,

    Thank you for reading our blog and reaching out.

    The Sharks’ practice of jumping out of water is called breaching. There are several reasons why Sharks breach. It’s considered that they do this to communicate and send different signals to their significant others or competitors. There’s also a belief that by breaching they want to shake off the parasites and small fish from their skin. But what we know for certain is that they jump out of water when they’re after the fast-moving prey like seals. The jump at the end of the high-speed chase enables Sharks to snatch their meal more efficiently.

    Hope you liked the answer 😉

    Take care,
    Tanya

I honestly think all sharks aren’t vicious. Yes they are deadly but its not like they just were swimmin around and were like “hmmm… lets be vicious and kill a bunch of things today.” Honestly I think they are highly stereotyped and misjudged type of fish. They probably just want to chill and swim around.

    Hi Chloe,

    Thanks for sharing, and that’s a very good point.

    Sharks are fascinating creatures in more ways than one. They are top-tier predators, but they almost never intentionally attack humans. When they do, it’s actually a case of mistaken identity or because they feel threatened. In fact, if you compare the annual number of deaths attributed to Sharks (around 10), to how many Sharks are killed by humans every year (100 million!), you’ll see a completely different picture.

    Check out our article to learn some more fascinating facts about Sharks.

    Thanks for reading and have a great day!

    You’re absolutely right – nothing messes with Ocras besides aquarium owners, and even that’s a bad idea.

    Absolutely!!!
    Which shows we are the #1 PREDATOR….. even Orca’s can’t escape our traps/ weapons. I think they are all gorgeous and well adapted to their world and we should leave them there. We have tried to ‘possess’ a White shark many times ( by we… I mean places like Sea World) and they die every time!!
    Orca’s rule their part of the Ocean, Bull’s rule shallows/ fresh water/ White’s rule deep water and Tiger’s…. well, they eat anything….. including us.
    We feel people should rule every living thing on earth…. and we should stop.
    Orca’s / Dolphins ( smaller) are just social enough to like us— most of the time. Lol

Nice article, only thing is bull shark size is downplayed a little and great white the opposite. They often do reach 11-12ft and a particularly large specimen was just over 13 ft. Great whites could potentially reach 25ft, but it’s never been 100% confirmed as the very largest individuals are around 21ft. There are quite a few reports of 23ft great whites, but they have never been confirmed.

    Hi there,

    Thanks for getting in touch!

    Perhaps I did sell Bull Sharks a little short (no pun intended), although 13 feet would be a real monster.

    The problem with Great Whites is that people interact with them so rarely that it’s tough to say how big they really can get.

    Either way, you make a fair point – I might have been overdoing the size difference. I’ve updated the article to be a little clearer.

    All the best!

Bull shark would win because they have more jaws than a regular shark 50 jaws it would make a more dangerous bite and they are more agressive and they would be the first to attack and it’s would have about 350 sharktooth bites because the bull shark have 7 teeth in 1 jaw 50×7 is 350 teeth in total so the bull shark would win!😋

    Hi LK,

    Thanks for reading!

    You’re right that Bulls are very aggressive, but they don’t usually go for prey bigger than themselves.

    In terms of the teeth, you make an interesting point. Bull Sharks can have 350 teeth in their mouth at any point – seven “series” of 50 teeth.

    However, only one series of teeth is usually in use at a time. The others are folded back, ready to take their place.

    Either way, it’s not a battle you’d want to see up close!

    All the best.

    I love mako sharks I even have my profile named after a stuffed animal of a mako shark I have
    But they seem to be clapped on by every single shark
    They don’t even have a bark and they definitely don’t have a bite They’re just fast
