Sharks are often perceived as dangerous predators, but new research suggests that some shark bites may actually be a form of self-defense rather than a planned attack.
Although shark bites are rare, with only about 100 reported each year and about 10% fatal, researchers have found that some bites occur when sharks feel threatened by human activity. These “defensive bites” can be caused by people trying to spear fish near a shark, grab one, or even just swim too close.
A study led by Dr. Eric Clua of PSL University shows that these bites are driven by instinct, not aggression. In many cases, the bites cause only minor injuries, similar to the defensive response of other animals.
The researchers analyzed bite data from French Polynesia and global records and found that 3-5% of bites may be due to self-defense.
Scientists urge people not to touch or interfere with sharks, even if they appear injured or calm, as sharks may perceive any contact as a threat.Source: phys.org
