Government researchers have tagged 338 sharks with acoustic transmitters that monitor where the animals are. When a tagged shark is about half a mile away from a beach, it triggers a computer alert, which tweets out a message on the Surf Life Saving Western Australia Twitter feed. The tweet notes the shark’s size, breed and approximate location.
