Beach-goers swimming on the coast of Western Australia now have less cause to scan the horizon for a dorsal fin before wading into the water, thanks to a new Twitter feed that alerts them when a shark is lurking nearby.
Scientists attached electronic transmitters to over 320 sharks, including a number of great whites, and are now able to track the fish as they swim through the ocean. When one of the sharks swims within one kilometer of the shoreline, the transmitter sends a signal to an underwater receiver, which then triggers an automatic tweet in a feed belonging to Surf Life Saving Western Australia (@SLSWA).
