Ever wondered if those toothy predators lurking beneath the waves have a taste for technology? You're not alone! The myth of sharks attacking GoPros is a popular one, and I decided to dive in (literally!) to see if there's any truth to it.
Let me tell you, nothing quite compares to being face-to-face with a shark. Their sleek bodies, those intense eyes – it's both terrifying and exhilarating. But to really understand these creatures, we need to separate fact from fiction.
Do Sharks Mistake GoPros for Food?
The theory goes that the electromagnetic waves emitted by a GoPro resemble the signals given off by prey, making sharks more likely to attack. To test this, I teamed up with my marine biologist buddy, Luke Tipple, and we headed to shark-infested waters (because, why not?).
We each took a selfie stick – one with a running GoPro, the other with an empty GoPro housing. The goal? See which one attracted more attention. While the sharks did bump the running GoPro more frequently, it wasn't a dramatic difference.
So, we decided to crank things up a notch! Imagine a rig with 21 GoPros – talk about a shark buffet, right? Surprisingly, they weren't that interested.
Here's the takeaway: Sharks can likely sense the electrical field from a GoPro, but it's not enough to trigger a feeding response. Think about it – they've evolved over millions of years to hunt; a GoPro just doesn't register as a tasty meal.
Beyond the GoPro: Sharks' Super Senses
Sharks are incredible sensory machines. They don't just rely on sight, smell, taste, touch, and hearing like us. Oh no, they have two bonus senses:
- Electroreception: Remember those electromagnetic fields? Sharks have special pores, called ampullae of Lorenzini, that allow them to detect these fields, helping them find hidden prey.
- Lateral Line: This sensory system, running along their bodies, detects pressure changes in the water. It's like a sixth sense for movement, allowing them to navigate and hunt even in murky water.
"Part of the reason sharks have existed as apex predators for 450 million years is because they detect and hunt their dinner, not only with the same five senses we do, but with two bonus senses as well." - Mark Rober
More Shark Myths: Busted!
The GoPro myth is just the tip of the iceberg. Here are a few more common misconceptions about sharks:
- Sharks Can Smell a Drop of Blood From a Mile Away: While sharks have a keen sense of smell, it's not quite that extreme. The actual range depends on factors like water currents and the type of blood.
- Sharks Are Mindless Eating Machines: Sharks are intelligent creatures with complex behaviors. They're not just out to get us!
- All Sharks Are Dangerous: Out of the hundreds of shark species, only a handful pose a significant threat to humans.
Respect, Not Fear
Sharks are essential to the health of our oceans. Instead of fearing them, let's appreciate their role in the ecosystem and work towards their conservation.

So, next time you're in the water (with or without your GoPro), remember that sharks are more than just sharp teeth and scary stories. They're a vital part of our planet, deserving of our respect and protection.
