Narrated by Paul McGann, the behaviour of the ocean predators goes under the microscope with fascinating results. The first film reveals their many hunting methods from blacktip sharks gathering in huge packs to tasselled wobbegongs, which ambush their prey.
There's also a look at the speedy mako shark that can swim at 46mph and the Greenland shark which can apparently live for 200 years.
Then there are whitetip reef sharks - masters of night-time hunting - and, of course, the infamous great white, shown here stalking seals off the coast of South Africa.
The show is followed by a short behind-the-scenes film reveling how the episode was made.
