Do great white sharks hunt at night?

Sharks can be diurnal or nocturnal. Some are both however most are one or the other. Also sharks don't actually go out and attack in the sense they are murdering something, they eat food like all animals do and because some humans have interfered (usually unintentionally) sharks have been thought of as killers. I'm pretty sure we have killed a lot more animals for food than sharks have killed us. Nevertheless we need to eat other aniamls to survive so we aren't doing anything wrong.
