Scientists have found the world’s first hybrid sharks in waters off Australia – a discovery that researchers said could have implications for the whole world.
The predators are a cross between the common blacktip shark and the Australian blacktip shark.

Dr Jess Morgan, of the University of Queensland, said it was unusual for sharks to breed this way: ‘Sharks physically mate, which is usually a good way to make sure you don’t hybridize with the wrong species.’
