they are diurnal because they are never spotted during the night. they always apear at the surface during the day not the night. eventhoug people say that they are nocturnal i think that they are diurnal. if you think that you are a smart person please think. when have you ever seen a picture of a killer whale are any whale at night? think and dont be and idiot
WELLLL.. i beg to differ..
I know for a fact that blue whales do not sleep. This is because if they did, then they would drown. Think about it, how to whales breath? through their blowholes. How do they breath if they are sleeping? They don't. That's why most whales, it not all, are neither nocturnal or diurnal, because they dont sleep. Also, whales dont have involuntary breathing, they have to think about breathing and they have to make sure that they actually breath every 30 minutes or so. They do, however, take little napes now and then, but other than that, they get their energy from their food. Now it's time for you to think and stop being an idiot because CLEARLY most of the whales would be dead if they slept. If you dont believe me, then look up 'do whales sleep', and you'll find that they either dont sleep, or half of their brain sleeps at a time, like dolphins.

However, most studies have been done during the day when it's relatively easy to see the animal's behavior, so it's possible that this is a biased conclusion and with more studies we may find these animals are very active at night as well.
