Scientists Discover Surprisingly Simple Way to Avoid Shark Attacks

Why Sharks Bite Humans: It’s Not What You Think
Since Jaws terrified audiences in 1975, sharks have been cast as ruthless predators. But new research reveals a surprising truth: many shark bites are acts of self-defense, not aggression. Scientists urge swimmers and divers to rethink their approach to these misunderstood creatures.
The Self-Defense Hypothesis
A study published in Frontiers in Conservation Science challenges the myth of the “mindless killer” shark. Researchers found that sharks often bite humans when they feel threatened, such as during accidental encounters or when humans invade their space. Dr. Eric Clua, a shark expert, explains: “Defensive bites are a survival instinct. The shark isn’t ‘attacking’—it’s reacting to perceived aggression, like a cornered animal.”
Key findings include:
- 10% of annual shark bites are fatal (around 10 deaths per year).
- Most incidents occur due to territorial behavior or human provocation (e.g., touching, chasing, or crowding sharks).
- Even seemingly calm or injured sharks may bite if they feel trapped.

Why Respect Matters
Sharks are far more at risk from humans than vice versa. Humans kill over 100 million sharks annually for fins, sport, or accidental bycatch. In contrast, 2023 saw just 47 unprovoked bites globally. Dr. Clua emphasizes: “We’re visitors in their habitat. Avoid touching or approaching sharks—even if they appear calm. Respect is key to coexistence.”
How to Reduce Your Risk
- Keep your distance: Never approach, touch, or feed sharks.
- Avoid erratic movements: Splashing or panicking can mimic prey behavior.
- Steer clear of fishing zones: Sharks may be drawn to bait or struggling fish.
- Heed local warnings: Avoid swimming at dawn/dusk or near river mouths where sharks hunt.

The Bigger Picture
While 2023 marked a 30-year low in bites, climate change and habitat loss are pushing sharks closer to shores. Experts stress that education, not fear, is the solution. “Sharks aren’t monsters,” says marine biologist Dr. Diego Vaz. “They’re vital to ocean health. Our actions—not theirs—determine the risk.”
In short: Give sharks space, and they’ll likely return the favor.
