The sand tiger, or ragged tooth shark, is a sinister-looking humped back creature with a mouthful of wicked teeth - the embodiment of nightmares. Yet it is hardly the vicious killer of our imagination and on a reef off the coast of South Africa divers have grown to love this ugly shark. In this episode we follow the ragged tooth shark from its summer habitat in the Cape to its winter mating waters in KwaZulu-Natal. (Diver/shark interaction to show how close divers actually get to the sharks)
