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.
