Clearly its not hungry and it knows the diver isn’t food. White sharks don’t eat people. Tiger sharks have been known to though. Sharks are somewhat predictable so a skilled and alert person can avoid being their meal. Its recommended you don’t look like their main food. Here you can see the diver is wearing stripes that is for good reason. Many attacks happen when people jump into the water off the boat . Dont jump in but ease yourself in. And dont stir up blood and guts like spear fishermen and abalone divers do. If you bait the water all bets are off. Orcas are the apex predator of the sea and they eat white sharks. In the last few years they have actually driven the whites to deep depths where the orcas can’t go and sittings have been fewer and fewer. Personally I worry about encounters with pittbulls more than sharks.

I've surfed with sharks around, and consider myself extremely lucky to have never been bit. Shark researchers claim they are massively misunderstood creatures. All I know is they can detect your heartbeat from 100 miles away, and sense your blood in the water down to the ppm level. That's enough to scare the sh!t out of me.

Charles Manson was misunderstood too. How did that work out Itchy?

They can detect your heartbeat from 100 meters away. If you are talking or splashing, they can hear that 1 kilometer away, and can smell blood .5 km away. Sharks can detect changes in electrical fields at 5 nV/cm which means they can detect a difference of one-billionth of a volt at 1,600 km. That may make you think twice about what kind of electrical field your flashlight, watch and dive computer are emitting.
I've been on hundreds of dives and only had one where I was scared of sharks. On this dive off of Freeport, the idiots in another boat were cleaning their catch and throwing the carcasses in the water unbeknownst to us. Hundreds of sharks showed up and you could tell that a frenzy was beginning. My brother and I got out of the water and gave the other boat the old one finger salute. We had a dive flag up.

Not that it matters, but the part about detecting electric fields is highly overstated. They are certainly sensitive to electroreception, but not to that degree. Here's everything you ever wanted to know about it - using the 5 NV/cm claim... https://www.wired.com/2013/08/how-sensi ... ic-fields/

That makes sense. I shouldn't have blindly trusted Shark Week.
i haven't done anything like that but i once when i was hiking out in montana i came around a corner and right there on the edge of the trail stood a very large male grizzly. snorted at us twice. i measure his tracks and ours after the encounter, which lasted about 20 minutes. 15 of my boots, heel-to-toe.
what i can tell you is this: i have had a guy try to rob me at gun point, almost got killed riding my motorcycle a couple of times but there is NOTHING, and i seriously mean nothing, that can compare to coming face to face with an animal higher up on the food chain than you. well, being in an out-of-control bush fire/wildfire is bad too.
i have no idea how that person swims with that shark. that is some nightmare stuff and being out of our natural land-habitat and being in theirs is just some crazy stuff.
