Seven metre 'Jaws' shark creates Facebook frenzy
A seven-metre-long shark which is about the same size as the monster featured in the movie Jaws has created a Facebook frenzy after being sighted off South Australia.
The great white shark was spotted from the air at Marino Rocks, forcing the evacuation of swimmers.
It was about 200 metres off shore.
The Westpac Lifesaver Rescue helicopter tried to herd the shark out to sea.
It made its way in to deeper water and had not been seen again.
Police were alerted by surf lifesavers and participants at a junior Surf Life Saving Carnival at nearby Seacliff beach were cleared from the water, AdelaideNow reported.
"It's the biggest I've ever seen as a crew member in the Westpac chopper. We put it down as 7m the photo really doesn't do it justice," an unnamed crew member wrote on the Facebook page of Shark Alerts SA.
Understandably, the picture of the shark has sparked plenty of comparisons to the movie Jaws.
But Surf Life Saving SA says while there has been an increase in sightings, the risk to the public is not any greater this year than in the previous years.
There have been 53 shark sightings so far this season, compared to 30 sightings same time last year and 39 sightings in 2013/14.
Large schools of bait fish, however, have prompted swimmers to be cautious.
