In many parts of the world, shark attacks are a very real possibility for anyone entering the ocean. While suspended nets do help keep the toothsome fish separated from swimmers, they’re far from from 100 percent reliable, plus sharks (along with other marine animals) regularly get caught in them and perish – as sharks are one of the ocean’s apex predators, removing them from the ecosystem could have disastrous consequences. The Clever Buoy, however, may prove to be an effective method of keeping humans and sharks apart, with no harm coming to either.
