Zothecula writes "More shark attacks occur in Western Australia than almost anyplace else on Earth. In order to help protect swimmers and surfers, the state government relies largely on helicopter-based spotters, plus members of the public who report their own sightings. Now, however, the Department of Fisheries has introduced a new system, in which the toothy fishes announce their own presence via Twitter. Known as the Shark Monitoring Network, the system utilizes acoustic tags that are attached to the fins of individual sharks, along with buoyed monitoring devices that pick up the signals transmitted by those tags. When a tagged shark swims within range of one of the monitors, its species, size and location is automatically recorded."
