Blue Reef Adventures: Grinning Predators: Ragged-Tooth Sharks of South Africa (1998)
Over the years, sharks have attacked off the coast of South Africa with a chilling regularity. One suspect in these grim assaults has been a species known as the sand tiger, or, in South Africa, the ragged-tooth shark.
With its sinister hunched back, a menacing mouthful of teeth and a daunting ten-foot length, the ragged-tooth shark is a fearsome-looking predator. In colder waters, this could make for a dangerous encounter, but in the warm waters of the Natal reefs, the ragged-tooth shark undergoes a dramatic change of personality.
