Image via WikipediaWe've all seen Jaws, but believe it or not most shark attacks don't end up with swimmers being dragged around in circles so that they look like they're being sucked down a plughole.
In fact there are three main types of unprovoked shark attack, and the experience and chances of survival vary dramatically depending on the behavior and intentions of the shark.
Here is a breakdown of what each one consists of.
More often than not sharks will "attack" humans out of curiosity having mistaken them for a seal or other more common form of prey.
These attacks occur in shallow waters and surfing spots. The shark will usually give the swimmer or surfer a single bite before retreating and will often not return, having realized the human is bigger than, or different to, its normal prey.
As the name indicates, this attack happens without warning. Unlike hit-and-run attacks, sneak attacks are thought to be the result of feeding or aggression rather than mistaken identity.
The attacks usually happen in deeper waters and will usually involve a number of bites or injuries, often proving fatal.
Similar to sneak attacks, these usually take place in open sea and will tend to involve multiple bites because the shark's intention is to attack the victim, rather than simply investigate.
The difference is in the shark's behavior. Rather than pouncing unexpectedly, the shark will repeatedly circle the victim and bump into them in a sign of aggression before actually attacking them.
