The sneak and surprise attack is quite dangerous and these incidents occur in deeper waters in which you don’t see the shark before it attacks. Typically, there is no initial contact which is why the chances of multiple bites is greater. The shark pulls out suddenly upon its prey on an surprise attack manoeuvre.

The sneak and surprise attacks may also happen in crowded beaches where lots of people could be swimming or surfing in the water. Very often swimmers on surf-boards appear as prey to the shark which might use this tactic to make a sudden grab.  Surfing, body surfing, boogie boarding, swimming, and snorkelling are all activities that activate this strategy for a shark to sneak up and  surprise you with an attack.
