Shark Week proved a surprise hit, the public’s fascination clearly unabated since Steven Spielberg’s Jaws became the blockbuster hit of the summer in 1975.
Recent reports of attacks on swimmers in New York and a sighting in Cornwall have caused further alarm.
Shark Week marks its 30th anniversary this week.
In 2017, a swimming race between US Olympian Michael Phelps and a great white shark similarly caused upset when it was found to be computer-simulated.
