Cape waters are home to one of the largest concentrations of great white sharks in the world. Fossil records, like the discoveries of preserved teeth found on the Cape flats, reveal their presence here for thousands of years. The earliest records of interactions between people and sharks in Cape Town are more than 100 years old. More recently research tells us that areas like False Bay are most likely critical habitats for the South African population, meaning the sharks depend on this area for their survival. But, surviving on the doorstep of a major city, with a population of 3.5 million people, may just be the biggest problem these animals have to face.
