The man and the shark

Almost every day for 40 years, expert diver Jim Abernethy has been swimming with sharks at a patch of shallow crystal-clear ocean in the Bahamas known as Tiger Beach. At any given moment Jim can be surrounded by 30 or more tiger, reef and lemon sharks. But Jim has a unique relationship with these underwater predators who swim up to him for affectionate nose-rubs. He tells Outlook's Clayton Conn about removing fishing debris from their mouths with his own hands and his mission to change the world's perception of these endangered sea creatures.
