Sharks off the coast of Western Australia are now tweeting their locations to lifeguards and swimmers. Sky News explains:

Scientists have attached transmitters to more than 320 sharks, including great whites, which monitor their movements up and down the coast.

When a tagged shark swims within about a kilometre of a beach, it triggers an alert which is picked up by computer. That computer then instantly turns the shark’s signal into a short message on Surf Life Saving Western Australia’s (SLSWA) Twitter feed.

Sky News reports that Western Australia is the world’s deadliest place for shark attacks, and it’s hoped that tweeting sharks will turn that trend around.
