Researchers have found that sharks can bite humans in self-defence, often as a reaction to human aggression. A study led by Dr. Eric Clua highlights that these bites are rare and should not be viewed as attacks. The research, conducted in French Polynesia, shows that only a small percentage of shark bites are motivated by self-defence. The study calls for a reevaluation of how shark bites are labeled and emphasizes the need for respectful interactions with these animals.
