The question should be "why are they called 'killer whales' ?" . Killer whales or better known as Orca are really just a large species of dolphin. They belong to the family Delphinidae and have all the attributes of smaller dolphin species.
Well, kind of. A killer whale is a kind of dolphin. And the killer whale (also known as an orca) may eat a dolphin sometimes. It may also eat a small whale. They got their nickname from their big diet.
The killer whale. The ones around California even eat elephant seals. Of course the Killer whale is not a real whale but a giant dolphin but do you wish to make that distinction.

The great white is the most considered a dolphin-killer.
well the sound that it makes is kind like a crying sound, or mostly like a whistle!
No, a Sperm whale is not a kind of dolphin.

It is sad to say but Humans can kill Orca (Killer Whale) Another Killer Whale could kill a killer whale. Orca (Killer whales) are Apex Predators which means they are really not hunted for food by others in the sea. A Blue whale can kill an Orca (Killer Whale) with just one strike of it's tail. A Sperm Whale could also kill an Orca if it was being attacked either with it's teeth or its tail. Some would say the Great White Shark, There is much evidence to prove (Including video) that killer Whales can kill a Great White Shark, it could depend on if the Killer Whale is a young one or not. There is a National Geographic issue which has a photograph of a killer whale pod literally ripping a huge chunk blubber/flesh out of the front side of a grey whale while the whale is still alive & swimming. It is shocking but amazing. I believe the point was that it was the first photo that proved that killer whales would attack a massive whale.
I think the shark is related to the whale and dolphin, it kind of seems like a mix of them both.
