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.
To sum things up: dolphins, porpoises and whales are all whales too. Orcas however, more commonly known as killer whales (think âFree Willyâ), are dolphins too. I know what youâre thinking, if all whales are whales, and if dolphins and porpoises are whales, then maybe all whales are dolphins too.
