Great white sharks are one of the most feared sea creatures in the world because of their aggressiveness and ability to kill humans. New research shows that great white shark attacks on humans aren’t on purpose but rather to protect their young.
Researchers from the University of California, Santa Barbara, and the National Oceanic and Atmospheric Administration (NOAA) found that great whites are more likely to attack humans when their young are in danger.
The study, published in Marine Mammal Science, is the first of its kind to look at the relationship between the age of a shark and its attack rate, the researchers said in a statement.
They found the average age at which a human was attacked by a great White shark ranged from 12 to 15 years old, with an average of 11 attacks per year.

Do great white sharks attack people?
In a study published this week in the journal PLOS ONE, a team of researchers from the University of California, Santa Barbara (UCSB) and the National Oceanic and Atmospheric Administration (NOAA) found that great whites were more likely than other shark species to approach and attack a human if they thought the person was a potential meal.
The study, led by UCSB marine ecologist and study co-author Dr. Michael J. O’Brien, is the first of its kind to look at the relationship between shark behavior and human-shark interactions, and it suggests that humans may be more vulnerable to shark attacks than previously thought.
“Shark attacks on humans are extremely rare, but they do happen,” said O’tbrien, who is also an associate professor of marine biology and a member of the U.S. National Science Foundation’s (NSF) Division of Ocean Sciences.
Has a shark ever eaten a full human?
In a horrific incident, a huge white shark swallowed a man who was swimming at Sydney beach in Australia on Wednesday. A witness captured the fatal shark attack. The man, who has not been named, was in the water with a friend when he was attacked by the shark, according to the Sydney Morning Herald.
Which shark has killed the most humans?
As of april 2021, the great white shark is responsible for the highest number of unprovoked attacks and deaths. The world record for a shark is held by the Great White Shark (Carcharodon carcharias), which was caught off the coast of South Africa in 2002. The shark weighed in at more than 1,000 pounds and measured nearly 30 feet long. .
Are sharks afraid of dolphins?
Like we check under our beds for monsters, sharks check for dolphins before nodding off. The toughest kids on the undersea block swim in fear of dolphins. We’ve put together a bunch of facts to tell you why. Flexibility gives dolphins the upper hand in swimming. They can reach speeds of up to 40 miles per hour, and they can dive to depths of more than 1,000 feet. But they’re not the fastest swimmers on earth.
Dolphins are actually the slowest. According to a study by the National Oceanic and Atmospheric Administration (NOAA), the average dolphin can only swim at a maximum speed of 15 miles an hour. This means that dolphins can’t outrun a speeding car or run a marathon in a matter of seconds. Dolphins are also the most flexible creatures in the animal kingdom.
In fact, they are the only animals that can flex their entire body at the same time. When a dolphin flexes its tail, for example, it creates a vortex that sucks in air and pushes it out the back of the dolphin’s mouth.
What does it mean if a shark is circling you?
It is prejudice. sharks do not circle in the water before they attack, it is their way of trying to form an image of what they are confronting in the water This motion is a sign of pure curiosity and not an incentive to attack the shark according to my own observations.
Shark attacks are rare, but they do happen. If you see a shark, don’t be afraid to approach it and try to get a better look at it. You may be surprised at what you find.
Can a shark smell period blood?
The bodily fluids that are released into the water are likely to be detected by sharks. A shark’s sense of smell allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just as it would be on land.
“It’s possible that a female shark might be attracted to the scent of a menstruating female, and that the male shark would then mate with the female,” said Dr. David Goulson, a professor of marine biology at the University of California, Santa Cruz, who was not involved in this study.
