    Hybrid Sharks Discovered

    This undated handout photo received by AFP on January 3, 2012 from the University of Queensland and taken by the New South Wales Department of Primary Industries (NSWDPI) shows a hybrid black tip shark containing both common and Australian black tip DNA in Australian waters.  Scientists said on January 3, 2012 that they had discovered the world's first hybrid sharks in Australian waters, a potential sign the predators were adapting to cope with climate change. The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, a lead researcher told AFP.

    Jaws 2.0? Scientists identified the first-known hybrid shark off the coast of Australia. The researchers found multiple generations of a shark that is a mix between the common blacktip and the Australian blacktip, which lives in warmer waters. The researchers say the findings are unprecedented and that they don’t know what's causing the sharks to interbreed, but that overfishing and climate change are being investigated. The hybrid appears better at surviving in a wider range of water temperatures.
