Are Sharks Aggressive Toward Divers?
It’s one of the most asked questions about shark diving in Hawaii. The reality? The species you’ll encounter—like Galapagos sharks and Sandbar sharks—are naturally curious and generally not aggressive toward humans.

Contrary to popular belief, sharks are not mindless predators. Most incidents involving sharks occur in murky water or involve mistaken identity (like surfers or spear fishers). Shark dive operators carefully choose locations and times to avoid these scenarios entirely.
Another persistent myth is that sharks prefer human flesh. As explained in our myth-busting article, sharks are opportunistic eaters, not manhunters, and there's no evidence that they deliberately seek out humans as prey. The fear of sharks has been largely shaped by fiction and media, not science.

Has There Ever Been a Shark Attack During a Shark Dive?
So to be clear: no unprovoked shark attacks have occurred during commercial shark diving tours in Hawaii. According to the Hawaii Department of Land and Natural Resources (DLNR), past incidents involving sharks and tour participants have been classified as provoked bites, typically linked to the use of chum or specific human actions.
The takeaway: shark diving in Hawaii remains safe when conducted under professional guidance and with responsible practices.

Is it Safe to Dive with Sharks When You Have a Cut or Are on Your Period?
This is a common concern, but the truth is: having a small cut or being on your period does not automatically increase your risk when diving with sharks.
Scientific studies and real-world experience from thousands of shark dives suggest that sharks are not attracted to human blood in the way many people imagine. Unlike the dramatic scenes shown in movies, sharks don't go into a frenzy at the presence of a few drops of blood. Their interest is primarily in the scent and vibration patterns of injured or distressed prey animals like fish.
That said, there are still a few best practices:
If you're on your period and feel comfortable, you can safely participate, many female guides and divers do this regularly with no issues.
Always inform your guide if you have concerns so they can provide personalized advice based on the dive conditions.
The key is to follow guidance, stay calm in the water, and trust your trained dive leaders.

What do I need to know before diving with sharks in Hawaii?
Before you choose a shark diving tour, make sure the company follows responsible and professional safety practices:
Make sure they do not use chum or attractants to lure sharks, as this can alter natural shark behavior.
Make sure there is a trained safety diver onboard to monitor conditions and assist in case of emergencies, and in the water with you at all times, monitoring wildlife behavior and conditions.
Make sure they carry a complete first aid kit and have clear emergency response protocols in place.
Make sure they do thorough briefing before getting in the water.
Make sure the company is eco-friendly and conservation-minded.
In the water, there are also a few tips that help keep interactions calm and safe:
Maintain awareness of your surroundings including the wildlife, your guide, and the boat.
Avoid splashing or panicked movements—this can startle sharks or attract unwanted attention.
Stay close to your guide and follow their instructions at all times.
Keep your movements slow and steady to appear non-threatening.
These safety measures and behavioral tips reflect a company’s professionalism and your own role in contributing to a respectful, safe shark diving experience.
