and it's hard to be surprised that attacks happen. However, given the size and power of both these predators, and the relatively weak and poor swimmers humans make, I think if sharks truly saw humans consistently as food, and sought them out to kill them, humans would be dying a lot more often, rather than just losing limbs.
I could be wrong-- and there are exceptions to every rule (such as a crocodile who actively sought out humans as its preferred prey), but that's true of most animals, and I think if this shark were looking to be aggressive, this chap would fail to have a head anymore.
All that in mind, according to google we also are far more likely to be attacked by new yorkers than sharks, which, in hindsight, really isn't that surprising.

From what I've seen and learned of sharks, there don't seem to actually be that many cases where they're actively looking to hunt humans. Humans aren't a thing they would know to be a food source, and, even just from a practical perspective, eating things you don't recognize is usually a decent way to end up with your digestive system liquefied because that harmless fish you caught actually had level 100 poison, or releases so much slime you're now suffocating on it-- and still hungry.
I think they are much like crocodiles, however. A lot of crocodile attacks happen in places where people are taking animals such as cattle to rivers to drink. Crocodiles eat cattle. Likewise, most human attacks seem to occur when humans are splashing about and making a racket near the surface-- a behaviour sharks typically would associate with something injured, or vulnerable seals, dolphins, or birds. Enter an area where their typical prey often frequent-- especially if that prey is nearby-- (cont)
