According to a report in BBC Science News’ Great white’s marathon sea trek, conservationists and scientists investigating how far great white sharks migrate, found some of them migrate from South African to Mozambiquan territorial waters.
…Ramon Bonfil of the Wildlife Conservation Society in New York, US, and colleagues were stunned by the epic journey of the shark…”We suspect that she went for reproductive reasons,” Dr Bonfil said.“There’s plenty of food around South Africa and she would be using too much energy to just go to Australia to feed. Of course we can’t prove this at this stage, it is just a hunch.”
Great whites were once thought to keep to coastal regions, but this was a trek across a vast expanse of open ocean.
