Great white shark population threatened
A new survey has found that the population numbers of great white sharks (Carcharodon carcharias) off South Africa is about half what had been expected. A paper in Marine Ecology Progress Series shows the results of a six year study into the numbers of the apex predators and shows that there are only between 353 and 522 of the sharks. Of these, around 333 are of breeding age. (Image from Shutterstock).
