Although newspaper reports of escapes from shark attack normally state that the shark was punched on the nose, this isn’t the best idea. The centre for Shark Research in British Columbia say that the nose is 'not known to be a weak spot' and 'If you miss the snout its mouth is unfortunately very close by'. Much better, they say, to aim for a shark's most sensitive areas: its eyes and its gills. Most people who think they have punched a shark on the nose have actually been lucky and connected with one of these weak points by chance.
There are plenty of reports of people punching sharks and escaping, so there is little doubt that you should fight back. Any punch will increase your chances of escape, so if the nose is the only place you can punch then that's fine, but your chances of escape (and not losing a hand) will increase if you aim for a weaker spot.
One sure way of ensuring that a shark doesn't attack you is to turn it upside down; an inverted shark enters a natural state of paralysis. This state is called 'tonic' and the shark usually becomes dull and unresponsive for a while (about 15 minutes).

The Shark Attack File is maintained at Mote Marine Laboratory in Sarasota, Florida, and includes analysis of reports of shark attacks from as far back as 1580. Since 1580 about 2,200 attacks by sharks on humans have been recorded. This is equivalent to just 5% of the number of Americans injured by toilets in the year 1996. Bees, wasps and snakes all kill many more people every year than sharks do.
