More than 320 sharks off the coast of Western Australia are now tweeting their location automatically in an attempt to more quickly alert surfers and swimmers of potentially dangerous sharks in the area.
Scientists have attached transmitters to the sharks, among them tiger sharks and great whites, according to Sky News. When a tagged shark is detected within one kilometre of a beach, a computer automatically posts the shark's species, size, and approximate location on a Twitter account for Surf Life Saving Western Australia (SLSWA), a community beach safety organisation.
Western Australia is the deadliest place in the world for shark attacks. Six people have been killed by sharks in the past two years, up significantly from an average of one shark-attack death every eight years.
