Top 5 most deadly sharks for human beings!

Updated on April 16, 2012

Sharks don't usually attack humans. We are not their natural prey. We get attacked because we resemble some of their prey and the shark makes a mistake in murky waters. For example we look a lot like a seal swimming in water and seals provide sharks with the blubber (fat) so 90% of the shark attacks are just mistakes made by sharks. Very few sharks have attacked humans and only one or two are man-eaters. In this list i have rated sharks based on their aggressiveness and attacks on humans. You can participate in the poll too given in the end. Thank you

short-fin Mako

5. Shortfin Mako

The short-fin Mako is the fastest shark in the waters. It's speed is equivalent to that of a 'cheetah' on land. It has to be fast as it's prey the 'tuna' is also very fast. Both prey and predator share the same body features which make them fast.

Short-finned Makos are found world-wide in temperate and tropical seas. Makos range from the surface to relatively deep waters. They are pelagic oceanic swimmers, but are occasionally found inshore. In warm, tropical oceans, they swim deep below the surface as they prefer cool water

Mako sharks have attacked humans. Very few were killed more due to loss of blood or failure to get medical help quickly. Those that were attacked were divers and shark feeders. Mako's don't swim near the beaches so swimmers and surfers are relatively safe from this shark.

Oceanic white tip shark

4. Oceanic white tip shark

The oceanic whitetip shark is a stocky and heavy set animal and feeds on tuna, marlins and baracuda. They can however eat anything edible.

This shark is found far from the shore so pose no threat to surfers and swimmers. This shark species is found in the oceanic waters of the Atlantic, Pacific and Indian Oceans. In the Atlantic it occurs from northeastern Georges Bank, south to the Caribbean Sea and the Gulf of Mexico to Argentina. The specimens found in and around Canadian waters are at the northern most point of their range.

This is an aggressive shark. Many shipwreck victim survivals have seen this shark attacking the fellow victims. This shark in reality may have attacked more humans than all sharks combined. Those who do get attacked are divers and shark feeders.

Tiger shark

3. Tiger shark

Tiger sharks are named for the dark, vertical stripes found mainly on juveniles. As these sharks mature, the lines begin to fade and almost disappear.

They are the scavangers of the oceans and will eat almost anything even metal. This pose them as a threat to humans. They have attacked humans and many tiger shark specimens have shown human remains in their stomachs. This shark is blamed for many human deaths as it sometimes swim near the shore in pursuit of the turtles.

Tiger sharks are common in tropical and sub-tropical waters throughout the world.

They have earned the reputation of being a 'man-eater'

Great white shark
Great white shark

2. Great white shark

Many people feel this is the most deadliest of all sharks perhaps the images of the film 'jaws' influence their reasoning but this is not true. Great whites are not mindless killing machines but a curious fish like the cat we have as a pet.

Most attacks by this shark are by mistake. A human swimming in the ocean appears like a seal, great white's main dinner so the shark is bound to attack. Experiments have also shown a great white releasing the victims after a single bite. This shark has no interest in our bones and muscles. It is the blubber on a seal which the shark wants.

However a single bite of this shark can be fatal as the victim can bleed to death. It's best not to be in the same waters with this shark. the most dangerous water where these sharks have known to attack humans are on the coasts of South Africa and Australia.

Found in cool, coastal waters throughout the world, there is no reliable data on the great white's population.

This shark also has been called a 'man-eater'

Bull shark

1. Bull shark

Bull sharks are the most dangerous of all sharks to human beings. They are the most aggressive of all sharks because of the high levels of testosterones in them. They have been known to attack humans and many scientists feel they are responsible for most of the deaths of human beings which are blamed on either tiger or great white shark.

They live near high population areas and can adapt even in fresh waters which make them doubly dangerous. This close proximity to humans and their aggressiveness make them the most dangerous shark for humans.

Bull sharks get their name from their short, blunt snout, as well as their pugnacious disposition and a tendency to head-butt their prey before attacking. They are medium-size sharks, with thick, stout bodies and long pectoral fins.

They are found cruising the shallow, warm waters of all the world’s oceans. Fast, agile predators, they will eat almost anything they see, including fish, dolphins, and even other sharks.

Like great whites this shark attacks humans out of curosity and has been named a 'man-eater'

      I go to Holden Beach, NC. About 5 years ago, there was a bull shark toying with me, my son and his best friend; toying so rough to the point it left my entire right thigh bruised while I was holding a child in each arm, slowly getting them back to shore. One of the head butts was so hard I couldn't believe I didn't fall under the water while holding the boys. Then this year, last week, my son and I were out in the bigger waves (full moon would have been coming that night) and all of sudden, inside the a wave I saw one coming right at me with it's mouth wide open. A hammer head. I wasn't scared like I should have been, at the time I was amazed at the beauty of this creature just riding inside the wave, slightly hidden, yet clearly visible........when all of a sudden my 16 year old yanked me out my trance and out of it's path. (whiplashed) We started swimming back in, and I got a terrible doomed feeling and told my son to stop kicking....then a giant fin went by him. Reality on my behalf finally kicked in, and it's crazy how now, just 5 years later, my son so much bigger and stronger and now is saving me:) Had it hit me, I surely would have had broken ribs if not more. I new there was a threat, but didn't realize the threat was as big as it was until we got back to Ohio and I started reading everything this week. I love the ocean, but now pretty hesitant. When we went back out the next few days, we saw a lot of stingrays, and a few smaller sharks, while others played in the water like nothing was going on. My son and I now have a difficult time not looking "into" the waves; where as before this incident we would just play like everyone else and be looking at the waves or over the waves. Now we concentrate on whats inside the waves. Makes it real hard to enjoy the water now that we have an entirely different view of things. Thanks for a great article added to the other articles I've been reading.

      If you go scuba-diving in tropical ocean waters be with others and you most likely wont die.

      Sharks are just like any other wild animals, they are just curious just try not to be too close to them or swim in protected areas and you would be fine :)

      Very good point Wendy, I think the shark may associate food with humans but not see humans as prey though. Mostly Only those smaller sharks are fed that have no threat to humans. Man-eaters should be best left alone. Thank you for your insight wendy, appreciate it :-)

      What do you think of the practice of sending people down in cages and chumming the sharks? Is this connected, as some say, to the increase in shark attacks on humans? Are more sharks associating humans with food because of this practice?

      Sand tigers rarely attack humans and are not known to be man-eaters.

      Bull sharks may appear harmless but are very aggressive as they attack most readily than any other shark and they can get quite big as well.

      Note of irony. Great white & tiger sharks-besides frequency of attacks were tempting "no brainers" for the worst because of their superior size. I "guessed "about 20 ya that the bull shark would be the most on par as far as documented attacks on humans, but of the 3, I was inclined to view the bull shark the least exceptional-at least size wise. Not all victims witnesses, & recuers readily identify an attacking species. I guessed the bull shark on my own, because of shark attacks in fresh water, where bull sharks are the most prevailant, making attacks by them easier to document. Bulls appear to be the most generic looking among the 3, & there could be several species that look like them. It was surprising to learn that the bull shark had exceptional threatfactors for an apparently generic species. The other 4 are pretty distinctive looking

      The shortfin mako's my favorite species. I wrote a short story about a mako shark from birth to death. I named her Foxbat in honor of the fastest combat plane in the world.

      One of the catches to my story is challenging the notion that mako sharks are natures lottery winners because their speed enables them to eat more often. I assume-evidently correctly-that makos HAVE to eat more often due to a higher metabolism. I later read in wiki that a mako's metabolism is about 6 times that of a sandbar shark. The mako's bigger, & metabolism seems to be inversely proportional to size(since shrews seem to have the highest). If that's true, that woould make the sfm's metabolism even more incredible. It can eat more, but it has to eat more, so the wolf is not much farther from the mako's door. This made for an ironic delemna for the protagonist.

      This was quite informative and very well written. I have a question which I cannot seem to find an answer. I recently visited Italy and was captivated by the city of Venice what with its massive river and channels and was curious whether sharks frequented it or if they happen into it at all. Unfortunately its hard to use the Internet to find an answer to this question as there was a crappy B-Movie called Sharks in Venice that came out a couple years ago and when I try to Google this question all i get is reviews and comments regarding this movie maybe you could shine some light on this for me.

      Not all sharks attack 1berry. And even the man eaters rarely attack. more people get killed by bee stings than shark attacks. Thank you for your comments. :-)
