Red Triangle Shark Attacks

Spanning the Northern California coastline, the 135-mile Red Triangle area has had more documented white shark attacks than any similar location on the planet. But why has this beautiful place become a shark battleground?

White sharks are massive, terrifying predators, weighing as much as two tons and growing up to 21 feet in length. But this alpha hunter’s superpower is not just strength alone – it has teeth perfectly designed for latching onto prey and slicing through flesh. Each serrated tooth resembles the shape of a dagger – and a white shark can grow as many as 3,000 teeth in its lifetime.

With just 135 miles to its name, the Red Triangle area is credited for over 50% of all documented white shark attacks on humans. But why are these torpedo-shaped sharks attacking humans in this location, and at such frequency?

Well, several vital rivers flow into the ocean in this region, and during July through October these waters are teeming with salmon and steelhead trout. And plentiful prey invites predators – seals and sea lions feed in these fish-stocked areas, and, in turn, draws the planet’s largest predatory fish. But the beautiful California coastline not only attracts wildlife – recreational sport lovers fill the beaches and shoreline waters each summer. And a hungry white shark can potentially perceive a surfer as the wrong shape, at the wrong time.
