Grey Reef Shark Bites Henry Gibbs After 2-Hour Fiji Dive

Q: What critical mistake did this spearfisher make that turned a routine dive into a terrifying shark attack?

The critical mistake was underestimating the danger of spearfishing around several grey reef sharks and assuming a shark of that size was not a serious threat. Gibbs said himself that this was his error. He entered the water to hunt in an area where multiple sharks were already present, effectively competing with predators in their own feeding environment. Spearfishing can heighten risk because injured fish, struggling prey and blood in the water can attract sharks or trigger a feeding response. That appears to be the key factor that turned what might have seemed like a routine dive into a dangerous encounter. The video showed warning behavior before the bite: the shark was circling below the surface in semicircles before surging upward and attacking his calf. In shark-safety terms, that kind of close, repeated circling can be a sign to exit the water rather than continue diving. Gibbs later acknowledged that he was “in its environment hunting its food” and described it as “wrong place, wrong time.” The broader lesson from the incident is that even medium-sized reef sharks should not be dismissed, especially when spearfishing nearby and when several sharks are already in the water.

Q: Beyond escaping the jaws, what hidden deadly threat must shark attack survivors immediately fight to stay alive?

The hidden killer after a shark attack is catastrophic blood loss, followed closely by shock and serious marine infection. Emergency physicians and trauma guidance are clear that surviving the bite itself is only the start. Shark teeth can tear through major arteries, veins and muscle, and a victim can bleed to death within minutes if that hemorrhage is not controlled. That is why the immediate priorities are to get the person out of the water, stop the bleeding with firm direct pressure, and, if a limb wound is bleeding heavily and cannot be controlled, apply a properly tightened tourniquet above the injury. Severe blood loss can quickly trigger hypovolemic shock, when the body no longer has enough circulating blood to supply vital organs. Warning signs include pale or clammy skin, rapid breathing, confusion, weakness and collapse. Keeping the victim lying flat, warm, still and calm can help while emergency care is on the way. After the first minutes, infection becomes a major threat. Marine wounds can be contaminated by aggressive bacteria such as Vibrio vulnificus, which can cause rapidly spreading tissue destruction, sepsis and even amputation in severe cases. Doctors stress that every shark bite needs urgent hospital treatment, not only for surgery and blood replacement, but also for antibiotics and close monitoring. In short, the deadly fight after escaping the jaws is against hemorrhage, shock and infection, with bleeding control the most immediate lifesaving step.

POV footage shows New Zealander Henry Gibbs being bitten in the back of the calf and pulled into a death roll by a grey reef shark during a Fiji dive.
Before the attack, Gibbs said one shark stayed close, circled tightly beneath the group, grew increasingly agitated and even charged toward the boat.
Gibbs believes boat disturbance, noise and activity in the water may have drawn the shark's interest, though he said the exact trigger is unclear.
Despite serious injuries, Gibbs survived, underwent four surgeries and a skin graft, and is now urging divers to watch for behavior changes, carry trauma gear and dive with trusted companions.
