ISAF curators emphasize that these numbers must be taken with a grain of salt as a result of attacking sharks are generally misidentified by victims and bystanders. Nonetheless, bull sharks, tiger sharks, and nice white sharks are thought of “The Huge Three” as a result of they’re greater than able to inflicting critical damage, and so they typically hunt in areas frequented by people.

How Nice White Sharks Hunt and Assault Their Prey
Rising as much as 20 ft lengthy and topping out at greater than 6,000 kilos, nice white sharks are the most important predatory fish on the planet. They’ve solely two pure predators: people and killer whales. Orcas hunt great white sharks, however they solely reach taking down the apex predators by teaming up on them. As proven in a recent video, a pod of whales will work collectively to herd an awesome white to the floor, the place they chew into the shark and feast on its organs.
Nice white sharks, nevertheless, are solitary predators. They rely primarily on their noses, ears, and ultra-sensitive mouths to hunt. Their ears are tuned to select 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 house in on their prey. Often known as ampullae of Lorenzini, these organs operate like lateral strains in different fish species, detecting adjustments in electromagnetic fields and serving to them observe their prey with precision. Analysis reveals they can detect the impulses given off by an accelerated heartbeat, which implies they’ll actually sense concern.
Nice white sharks additionally use their eyes when searching, however their eyesight isn’t fairly as sturdy as their different senses, which may generally result in circumstances of mistaken identification. (Extra on this under.) They do lots of their searching in shallower waters close to the coastlines. That is for a pair causes: It’s the place a lot of their favourite prey sources congregate, and it’s simpler to ambush prey there.
When these modern torpedoes transfer in for the kill, they use their velocity and sheer energy to blindside their prey, usually attacking from under. Nice whites will, at instances, launch utterly out of the water as they chew down with large pressure, utilizing their lots of of razor-sharp enamel 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 atmosphere and examine unfamiliar objects — just like how we use our personal fingers — and their style buds assist them determine whether or not the thing is edible or not. This helps clarify why attacking nice white sharks don’t all the time kill folks regardless that they’re greater than able to doing so with a single chew.
“Everybody needs to assume sharks simply get hold of seals, however they chew lots of issues that don’t resemble any of their recognized prey,” shark professional and creator A. Peter Klimley defined to National Geographic years in the past. “They don’t tear this stuff to items. They take a chew, really feel them over, then transfer on.”

So, why would an awesome white shark exit of its approach to assault a human within the first place?
Klimley’s line of pondering touches on one potential clarification: 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, corresponding to a buoy, a kayak, or a boogie boarder.
The opposite predominant concept is that almost all nice white shark assaults on people are circumstances of mistaken identification. A shark senses an individual within the water, thinks they’re a seal or one other marine mammal, and chomps down on them.

As they surveyed the nearshore waters, they checked out the place folks and nice white sharks have been swimming in shut proximity to one another.
The researchers discovered that the overwhelming majority (91 p.c) of those 1,204 “human-shark-co-occurrences” have been at two places specifically: Carpinteria Seashore and Del Mar Seashore. 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 have been the folks most definitely to seek out themselves close to nice white sharks as a result of they typically ventured past the wave break.
Throughout this similar stretch of time, there was just one unconfirmed report of a shark chew alongside the 2 seashores, one of many research’s co-authors Chris Lowe told LiveScience.
“This research offers proof that top human-shark spatio-temporal overlap doesn’t result in an elevated chew frequency in southern California,” the authors write, “and there are a variety of attainable explanations as to why [juvenile great white sharks] usually are not biting water customers regardless of each day encounters.”
