The researchers observed 340 attacks by great whites on fur seals within 2km of Seal Island, in False Bay, South Africa. After each attack, the scientists recorded the precise geographical location and the depth of the water, as well as whether the attack was successful or not.
By applying these analytical techniques used by law enforcement in geographical profiling of criminal acts, including those by terrorists and serial killers., the researchers established that great white sharks also follow a similar hunting strategy.
The question of whether cephalopods can perceive sound has been controversial since the early 20th Century.
Most cephalopods lack gas-filled chambers within their bodies, such as the swim bladders that fish can use to hear. That suggested they could not detect the pressure wave component of sound.
