These investigations span from the current day to the late 16th century, and the outcomes have been mixed into the last word useful resource for shark assault statistics, often known as the Worldwide Shark Assault File. Importantly, these figures solely embody “unprovoked” shark assaults or bites — versus “provoked” incidents which can be initiated by people (feeding, harassing, or unhooking an awesome white shark caught from the seaside, for instance).
Listed below are these numbers at a look:
- Since 1580, there have been 949 unprovoked shark assaults documented around the globe

How Nice White Sharks Hunt and Assault Their Prey
Rising as much as 20 toes lengthy and topping out at greater than 6,000 kilos, nice white sharks are the biggest predatory fish on the planet. They’ve solely two pure predators: people and killer whales. Orcas hunt nice white sharks, however they solely reach taking down the apex predators by teaming up on them. As proven in a latest video, a pod of whales will work collectively to herd an awesome white to the floor, the place they chunk into the shark and feast on its organs.
Nice white sharks, nonetheless, are solitary predators. They rely primarily on their noses, ears, and ultra-sensitive mouths to hunt. Their ears are tuned to choose up on the low-frequency sounds of struggling critters, and so they can scent blood within the water from as much as three miles away. Nice whites then use tiny sensory organs round their mouths to dwelling in on their prey. Referred to as ampullae of Lorenzini, these organs perform like lateral traces in different fish species, detecting modifications in electromagnetic fields and serving to them observe their prey with precision. Analysis reveals they’ll detect the impulses given off by an accelerated heartbeat, which implies they’ll actually sense worry.
Nice white sharks additionally use their eyes when looking, however their eyesight isn’t fairly as sturdy as their different senses, which may typically result in circumstances of mistaken identification. (Extra on this beneath.) They do numerous their looking in shallower waters close to the coastlines. That is for a pair causes: It’s the place lots of their favourite prey sources congregate, and it’s simpler to ambush prey there.
When these smooth torpedoes transfer in for the kill, they use their pace and sheer energy to blindside their prey, sometimes attacking from beneath. Nice whites will, at instances, launch fully out of the water as they chunk down with great power, utilizing their a whole bunch of razor-sharp tooth to tear into their prey.
Not all bites are this savage, although. Like many shark species, nice whites additionally use their mouths to discover their surroundings and examine unfamiliar objects — just like how we use our personal fingers — and their style buds assist them determine whether or not the item is edible or not. This helps clarify why attacking nice white sharks don’t at all times kill individuals though they’re greater than able to doing so with a single chunk.
“Everybody needs to suppose sharks simply get your hands on seals, however they chunk numerous issues that don’t resemble any of their identified prey,” shark knowledgeable and creator A.

So, why would an awesome white shark exit of its strategy to assault a human within the first place?
Klimley’s line of pondering touches on one potential rationalization: curiosity. As a result of they’re on the tip-top of the meals chain, nice whites aren’t afraid to make use of their mouths to take a look at one thing that appears susceptible, similar to a buoy, a kayak, or a boogie boarder.
The opposite predominant principle is that almost all nice white shark assaults on people are circumstances of mistaken identification.

The researchers discovered that the overwhelming majority (91 p.c) of those 1,204 “human-shark-co-occurrences” had been at two places particularly: Carpinteria Seaside and Del Mar Seaside. They noticed nice whites swimming near people on 97 p.c of the times they flew their drone over the 2 seashores. Additionally they famous that surfers and paddle boarders had been the individuals most certainly to search out themselves close to nice white sharks as a result of they usually ventured past the wave break.
Throughout this similar stretch of time, there was just one unconfirmed report of a shark chunk alongside the 2 seashores, one of many examine’s co-authors Chris Lowe informed LiveScience.
“This examine offers proof that top human-shark spatio-temporal overlap doesn’t result in an elevated chunk frequency in southern California,” the authors write, “and there are a variety of attainable explanations as to why [juvenile great white sharks] should not biting water customers regardless of day by day encounters.”
