Australian shark warns of its approach to shore via Twitter

Biologists equip large sharks living off the coast of Australia with electronic tags that warn travelers about the danger. As soon as a shark with a “beacon” swims to the shore closer than a kilometer, the detectors located on the coast are detected. The message with the coordinates of the shark, as well as information about its breed and size is published on Twitter. This way of warning is much faster and more accurate than any other - usually it becomes known about the approach of a shark if it is accidentally noticed from a ship or from the shore. At the beginning of this year marked 338 sharks.

In Australia, six people have already died from shark attacks in the past two years, the highest in the world. But the mass extermination of sharks is unacceptable from an ethical and environmental point of view. Sharks reporting their approach using public tweets are an elegant and humane solution, scientists believe. Naturally, this is not a panacea - far from all predators living near the coast of Australia are labeled, besides sharks migrate in the ocean, sometimes overcoming vast distances. However, such an early warning system can significantly reduce the number of attacks if people are responsible for their security.

The battery life of electronic tags is up to 10 years. Information about the movements of sharks, in addition to warning travelers, has great scientific value - biologists have the opportunity to observe animals in real time from a distance, to better study their habits, habitat and migration routes.
