Are shark attacks on the rise? The short answer is yes.

The media has been full of attacks on swimmers and body boarders. In January, a New Zealand man survived being attacked by a shark, after fighting it off with a diving knife. According to the Sydney Morning Herald, junior doctor James Grant, 24, stitched his own wound onshore, before going to the pub for a beer... en route to the hospital!

In Hawaii, meanwhile, a rise in shark attacks has reportedly boosted the sales of devices which purport to clear surrounding water of sharks by emitting electric pulses.
