As the plight of sharks grows ever more increasingly dire, humans all over the globe are scrambling for ways to change the way the public sees sharks in an effort to boost their conservation. Many people are wont to believe that the shark is a mindless killing machine, operating only on instinct, and that instinct is to kill whatever lies in its path when hunger strikes. Researchers have asserted that this is not the case, and in fact, sharks don’t necessarily have a taste for human meat, but rather most shark bite incidents are exploratory nips on the shark’s end.
While it’s yet impossible to say just what is going on in the mind of a shark, scientists are developing ways to discourage shark interaction that is too close for comfort in a way that doesn’t harm the animal. Current methods include the use of magnetism, electronic fields, and chemicals that occur in nature that shark behavior has indicated is unappealing, such as the chemicals released from a dead or dying shark. This footage shows a live experiment carried out with a repellent made with dead shark tissues in a section of sea that is roiling with sharks. These experiments are of great value to shark conservation, as man continues to strive to reach an accord with the sea’s most fearsome predator.
