Orcas are called killer whales due to the fact that they are the top predator in the ocean. They are the hunters, not the hunted. They eat almost anything and everything they â¦ can find including other whales.
Killer whales are actually dolphins. They are the largest member of the dolphin family and are commonly referred to as orcas. A Killer Whale, or Orca, is the largest of the true dolphins, family Delphinidae. That is probably the only reason it is called a whale instead of a dolphin.
