This has a lot to do with their “heterothermy” mentioned in the last blog post. South Africa is a temperate sea, mostly cold water, especially in the Western Cape. If you look at other areas of the world with temperate seas (i.e. California, USA or West/South Australia) they also have white sharks in those areas. This is because white sharks are one of the few sharks specially adapted to tolerate cold waters. There are also plenty of seals in our area to keep the sharks well fed.
